About ICF and ICF connectors
The OpenICF (ICF) provides interoperability between identity, compliance, and risk management solutions. An ICF connector enables provisioning software, such as PingIDM, to manage the identities that are maintained by a specific identity provider.
ICF connectors provide a consistent layer between identity applications and target resources, and expose a set of operations for the complete lifecycle of an identity. The connectors provide a way to decouple applications from the target resources to which data is provisioned.
ICF focuses on provisioning and identity management, but also provides general purpose capabilities, including authentication, create, read, update, delete, search, scripting, and synchronization operations. Connector bundles rely on the ICF Framework, but applications remain completely separate from the connector bundles. This lets you change and update connectors without changing your application or its dependencies.
Many connectors have been built within the ICF framework, and are maintained and supported by Ping and by the ICF community. However, you can also develop your own ICF connector, to address a requirement that is not covered by one of the existing connectors. In addition, ICF provides two scripted connector toolkits, that let you write your own connectors based on Groovy or PowerShell scripts.
The ICF framework can use IDM, Sun Identity Manager, and Oracle Waveset connectors (version 1.1), and can use ConnID connectors up to version 1.4.

ICF architecture overview
ICF is situated between the identity management application and the target resource. The framework provides a generic layer between the application and the connector bundle that accesses the resource. The framework implements an API, that includes a defined set of operations. When you are building a connector, you implement the Service Provider Interface (SPI), and include only those operations that are supported by your target resource. Each connector implements a set of SPI operations. The API operations call the SPI operations that you implement.
The following image shows a high-level overview of an ICF deployment.
Understanding the ICF framework components
When you are building, or modifying, an identity management application to use the ICF Framework and its connectors, you use the following interfaces of the API:
-
Connector Info Manager Component
The connector info manager maintains a set of connector info instances, each of which describes an available connector. The ICF Framework provides three different types of connector info manager:
-
Local
A local connector info manager accesses the connector bundle or assembly directly.
-
Remote
A remote connector info manager accesses the connector bundle or assembly through a remote connector server.
-
OSGi
An OSGi connector info manager accesses the connector bundle within the OSGi context.
For more information, refer to Connector info manager.
-
-
Connector Info Component
The connector info component provides meta information (display name, category, messages, and so forth) for a given connector.
-
Connector Key Component
The connector key component uniquely identifies a specific connector implementation.
-
API Configuration
The API configuration holds the available configuration properties and values from both the API and the SPI, based on the connector type. For more information, refer to Configuration interface.
-
Connector Facade Interface
The connector facade is the main interface through which an application invokes connector operations. The connector facade represents a specific connector instance, that has been configured in a specific way. For more information, refer to ConnectorFacade interface.
When you are building a new connector, you implement the SPI, including the following interfaces:
-
The
connector
interface.The connector interface handles initialization and disposal of the connector, and determines whether the connector is poolable. For more information, refer to Connector interface.
-
The
configuration
interface.The configuration interface implementation includes all of the required information to enable the connector to connect to the target system, and to perform its operations. The configuration interface implements getters and setters for each of its defined properties. It also provides a validate method that determines whether all the required properties are available, and valid. For more information, refer to Configuration interface.
The ICF framework uses the configuration interface implementation to build the configuration properties inside the API configuration.
When the configuration interface is implemented, it becomes available to the default API configuration.
-
Any
operations
that the target resource can support, such asCreateOp
,UpdateOp
,DeleteOp
and so forth. For more information, refer to Operation interfaces.
Remote connector overview
Connectors can run locally (on the same host as your application) or remotely (on a host that is remote to your application). Connectors that run remotely require a connector server, running on the same host as the connector. Applications access the connector implementation through the connector server.
The ICF framework can support both local and remote connector implementations simultaneously. |
Connector servers also let you run connector bundles that are written in C# on a .NET platform, and to access them over the network from a Java or .NET application.
The following image shows a high-level overview of an ICF deployment, including a remote connector server.
For more information about connector servers, and how to use them in your application, refer to Remote connectors.
OpenICF API
This chapter describes how to use the ICF API, which lets you call ICF connector implementations from your application. The chapter demonstrates creating a connector facade, required for applications to access connectors, and then how to call the various ICF operations from your application.
Before You Start
Before you can use an ICF connector in your application, you must download the ICF framework libraries, and the required connector bundles.
The easiest way to start using the ICF framework, from Java, is to use the sample Maven project file as a starting point. This sample project includes comprehensive comments about its use.
To use a .NET connector remotely, you must install the .NET remote connector server, as described in Install .NET RCS. You must also download and install the specific connectors that you want to use from the BackStage download site.
You can now start integrating the connector with your application.
ConnectorFacade interface
An application interacts with a connector through an instance of the ConnectorFacade
class. The following diagram shows the creation and configuration of the connector facade. The components shown here are described in more detail in the sections that follow.
The connector facade is instantiated and configured in the following steps:
-
The application creates a
LocalConnectorInfoManager
instance (or instances) and adds the individual connector bundles (or assemblies).The
LocalConnectorInfoManager
processes these bundles or assemblies to instantiate aConnectorInfo
object.To be processed by the connector info manager, the connector bundle or assembly must have the following characteristics:
- Java Connector Bundle
-
The
META-INF/MANIFEST.MF
file must include the following entries:-
ConnectorBundle-FrameworkVersion
- Minimum required ICF Framework version (either 1.1, 1.4, or 1.5) -
ConnectorBundle-Name
- Unique name of the connector bundle -
ConnectorBundle-Version
- Version of the connector bundle
The combination of the
ConnectorBundle-Name
and theConnectorBundle-Version
must be unique.The connector bundle JAR must contain at least one class, that has the
ConnectorClass
annotation and implements theConnector
interface. -
- .NET Connector Assembly
-
The
AssemblyInfo.cs
is used to determine the bundle version, from theAssemblyVersion
property.The bundle name is derived from the
Name
property of the assembly. For more information, refer to the corresponding Microsoft documentation.If you change the name of your assembly, you must adjust the
bundleName
property in your connector configuration file, accordingly.The connector assembly DLL must contain at least one class, that has the
ConnectorClassAttribute
attribute and implements theConnector
interface.
-
For each connector, the
LocalConnectorInfoManager
processes theMessageCatalog
, which contains the localized help and description messages for the configuration, and any log or error messages for the connector.Your application can use this information to provide additional help during the connector configuration process.
-
For each connector, the
LocalConnectorInfoManager
then processes theConfigurationClass
, to build the configuration properties for the connector. -
Your application finds the connector info by its connector key. When the application has the connector info, it creates an API Configuration object that customizes the following components:
-
Object pool configuration
-
Result handler configuration
-
Configuration properties
-
Timeout configuration
The API Configuration object is described in more detail in The API Configuration Object.
-
-
The
ConnectorFacade
takes this customized API configuration object, determines which connector to use and how to configure it, and implements all of the ICF API operations.
Creating a ConnectorFacade
Applications access the connector API through a ConnectorFacade
class, and interact with the connector through a ConnectorFacade
instance.
The following steps describe how to create a ConnectorFacade
in your application.
-
Create a
ConnectorInfoManager
and acquire theConnectorInfo
object for your connector, as described in the previous section. -
From the
ConnectorInfo
object, create the defaultAPIConfiguration
.APIConfiguration apiConfig = info.createDefaultAPIConfiguration();
-
Use the default
APIConfiguration
to set theObjectPoolConfiguration
,ResultsHandlerConfiguration
,ConfigurationProperties
, andTimeoutConfiguration
.ConfigurationProperties properties = apiConfig.getConfigurationProperties();
-
Set all of the
ConfigurationProperties
that you need for the connector, usingsetPropertyValue()
.properties.setPropertyValue("host", SAMPLE_HOST); properties.setPropertyValue("adminName", SAMPLE_ADMIN); properties.setPropertyValue("adminPassword", SAMPLE_PASSWORD); properties.setPropertyValue("usessl", false);
-
Use the
newInstance()
method of theConnectorFacadeFactory
to create a new instance of the connector.ConnectorFacade conn = ConnectorFacadeFactory.getInstance() .newInstance(apiConfig);
-
Validate that you have set up the connector configuration correctly.
conn.validate();
-
Use the new connector with the supported operations (described in the following sections).
conn.[authenticate|create|update|delete|search|...]
Connector messages object
The Connector Messages interface sets the message catalog for each connector, and enables localization of messages. The interface has one method (format()
), which formats a given message key in the current locale.
For more information, refer to the corresponding Javadoc.
API configuration object
The API configuration object holds the runtime configuration of the connector facade instance. The ICF framework creates a default API configuration object inside the Connector Info object. The application creates a copy of the API configuration object and customizes it according to its requirements. The API configuration object includes the following components:
- Object Pool Configuration
-
The object pool configuration specifies the pool configuration for poolable connectors only. Non-poolable connectors ignore this parameter. The object pool configuration includes the following parameters:
- maxObjects
-
The maximum number of idle and active instances of the connector.
- maxIdle
-
The maximum number of idle instances of the connector.
- maxWait
-
The maximum time, in milliseconds, that the pool waits for an object before timing out. A value of
0
means that there is no timeout. - minEvictableIdleTimeMillis
-
The maximum time, in milliseconds, that an object can be idle before it is removed. A value of
0
means that there is no idle timeout. - minIdle
-
The minimum number of idle instances of the connector.
- Results Handler Configuration
-
The results handler configuration defines how the ICF framework chains together the different results handlers to filter search results.
- enableNormalizingResultsHandler
-
boolean
If the connector implements the attribute normalizer interface, you can enable this interface by setting this configuration property to
true
. If the connector does not implement the attribute normalizer interface, the value of this property has no effect. - enableFilteredResultsHandler
-
boolean
If the connector uses the filtering and search capabilities of the remote connected system, you can set this property to
false
. If the connector does not use the remote system’s filtering and search capabilities (for example, the CSV file connector), you must set this property totrue
, otherwise the connector performs an additional, case-sensitive search, which can cause problems. - enableCaseInsensitiveFilter
-
boolean
By default, the filtered results handler (described previously) is case sensitive. If the filtered results handler is enabled this property lets you enable case-insensitive filtering. When case-insensitive filtering is not enabled, a search will not return results unless the case matches exactly. For example, a search for
lastName = "Jensen"
will not match a stored user withlastName : jensen
. - enableAttributesToGetSearchResultsHandler
-
boolean
By default, IDM determines which attributes that should be retrieved in a search. If the
enableAttributesToGetSearchResultsHandler
property is set totrue
, the ICF framework removes all attributes from the READ/QUERY response, except for those that are specifically requested. For performance reasons, it is recommended that you set this property tofalse
for local connectors, and totrue
for remote connectors.
- Configuration Properties
-
The Configuration Properties object is built and populated by the framework as it parses the connectors configuration class.
- Timeout Configuration
-
The timeout configuration enables you to configure timeout values per operation type. By default, there is no timeout configured for any operation type.
Connector info manager
You need to create a ConnectorInfoManager
and a ConnectorKey
for your connector.
The ConnectorKey
uniquely identifies the connector instance. The ConnectorKey
class takes a bundleName
(the name of the Connector bundle), a bundleVersion
(the version of the Connector bundle) and a connectorName (the name of the Connector).
The ConnectorInfoManager
retrieves a ConnectorInfo
object for the connector by its connector key.
You must initiate a specific connector info manager type, depending on whether your connector is local or remote. The following samples show how to create a local connector info manager and a remote connector info manager.
ConnectorInfoManagerFactory fact = ConnectorInfoManagerFactory.getInstance();
File bundleDirectory = new File("/connectorDir/bundles/myconnector");
URL url = IOUtil.makeURL(bundleDirectory,
"/dist/org.identityconnectors.myconnector-1.0.jar");
ConnectorInfoManager manager = fact.getLocalManager(url);
ConnectorKey key = new ConnectorKey("org.identityconnectors.myconnector",
"1.0", "MyConnector");
ConnectorInfoManagerFactory fact = ConnectorInfoManagerFactory.getInstance();
File bundleDirectory = new File("/connectorDir/bundles/myconnector");
URL url = IOUtil.makeURL(bundleDirectory,
"/dist/org.identityconnectors.myconnector-1.0.jar");
ConnectorInfoManager manager = fact.getLocalManager(url);
ConnectorKey key = new ConnectorKey("org.identityconnectors.myconnector",
"1.0", "MyConnector");
Schema and supported operations
Different connectors support different subsets of the overall set of operations provided by OpenICF. When your connector is ready to use, you can use the ConnectorFacade
to determine which operations your connector supports.
The quickest way to check whether an operation is supported is to determine whether that specific operation is part of the set of supported operations. The following sample test checks if the CreateApiOp
is supported:
Set<Class< ? extends APIOperation>> ops = conn.getSupportedOperations();
return ops.contains(CreateApiOp.class);
Note that a connector might support a particular operation, only for specific object classes. For example, the connector might let you create a user, but not a group.
To be able to determine the list of supported operations for each object class, you need to check the schema. To determine whether the connector supports an operation for a specific object class, check the object class on which you plan to perform the operation, as shown in the following example.
Schema schema = conn.schema();
Set<ObjectClassInfo> objectClasses = schema.getObjectClassInfo();
Set<ObjectClassInfo> ocinfos = schema
.getSupportedObjectClassesByOperation(CreateApiOp.class);
for(ObjectClassInfo oci : objectClasses) {
// Check that the operation is supported for your object class.
if (ocinfos.contains(ocinfo)) {
// object class is supported
}
}
In addition to determining the supported operations for an object class, your application can check which attributes are required and which attributes are allowed for a particular object class. The ObjectClassInfo
class contains this information as a set of AttributeInfo
objects.
The following example shows how to retrieve the attributes for an object class.
Schema schema = conn.schema();
Set<ObjectClassInfo> objectClasses = schema.getObjectClassInfo();
for(ObjectClassInfo oci : objectClasses) {
Set<AttributeInfo> attributeInfos = oci.getAttributeInfo();
String type = oci.getType();
if(ObjectClass.ACCOUNT_NAME.equals(type)) {
for(AttributeInfo info : attributeInfos) {
System.out.println(info.toString());
}
}
}
Using the schema object, you can obtain the following information:
-
Object classes and their attributes
-
Operation options per operation
The following example shows how to retrieve the schema as a list of ObjectClass
objects, from the ObjectClassInfo
class.
ObjectClass objectClass = new ObjectClass(objectClassInfo.getType());
Operation options
Operation options provide an extension point to an operation, letting you request additional information from the application, for each operation. The connector framework includes a number of predefined operation options for the most common use cases. For example, the option OP_ATTRIBUTES_TO_GET
enables you to specify a list of attributes that should be returned by an operation. When you write a connector, you must define the operation options that your connector supports in the schema, so that the application knows which operation options are supported.
For a list of the predefined operation options, refer to the corresponding Javadoc.
ICF special attributes
ICF includes a number of special attributes, that all begin and end with __
(for example __NAME__
, and __UID__
). These special attributes are essentially functional aliases for specific attributes or object types. The purpose of the special attributes is to enable a connector developer to create a contract regarding how a property can be referenced, regardless of the application that is using the connector. In this way, the connector can map specific object information between an arbitrary application and the resource, without knowing how that information is referenced in the application.
The special attributes are used extensively in the generic LDAP connector, which can be used with PingDS (DS), Active Directory, OpenLDAP, and other LDAP directories. Each of these directories might use a different attribute name to represent the same type of information. For example, Active Directory uses unicodePassword
and DS uses userPassword
to represent the same thing, a user’s password. The LDAP connector uses the special OpenICF __PASSWORD__
attribute to abstract that difference.
For a list of the special attributes, refer to the corresponding Javadoc.
Connector instance management
The ICF framework supports multiple connector types, based on the implementation of the connector
interface, and the configuration
interface. These two interfaces determine the following:
-
Whether the connector instance is obtained from a pool or whether a new instance is created for each operation.
-
Whether the connector configuration instance is retained and reused for each operation (stateful configuration), or a new configuration instance is created for each operation (stateless).
Connector developers determine which type of connector to implement, assessing the best match for the resource to which they are connecting. The interaction between the connector
and configuration
interface implementations is described in detail in Connector types. This section illustrates how the ICF framework manages connector instantiation, depending on the connector type.
Instantiate a stateless, non-poolable connector
The most basic connector has a stateless configuration, and is not pooled. A basic connector is initialized as follows:
-
The application calls an operation (for example, CREATE) on the connector facade.
-
The ICF framework creates a new configuration instance, and initializes it with its configuration properties.
-
When the framework has the configuration instance, with all the attributes in the configuration set, the framework creates a new connector instance, and initializes it, with the configuration that has been set.
-
The framework executes the operation (for example, CREATE) on the connector instance.
-
The connector instance executes the operation on the resource.
-
The framework calls the
dispose()
method to release all resources that the connector instance was using.
The following illustration shows the initialization process for a basic connector, and references the numbered steps in the preceding list.
Instantiate a stateless, poolable connector
The second connector type has a stateless configuration, but can be pooled. A stateless, poolable connector is instantiated as follows:
-
The application calls an operation (for example, CREATE) on the connector facade.
-
The ICF framework calls on the object pool, to borrow a live connector instance to execute the operation.
If the object pool has an idle connector instance available, the framework borrows that one instance (step 5a in the illustration that follows).
The framework calls the
checkAlive
method on the customized connector instance with its configuration, to check if the instance that was borrowed from the pool is still alive, and ready to execute the operation. If the instance is no longer alive and ready, the framework disposes of the instance and borrows another one.The thread that borrows the object has exclusive access to that connector instance; that is, it is thread-safe.
-
If the object pool has no idle connector instances, the pool creates a new connector instance.
-
The framework creates a new configuration instance, and initializes it with its configuration properties.
-
The framework initializes the borrowed connector instance, with the configuration that has been set.
-
The framework executes the operation (for example, CREATE) on the connector instance.
-
The connector instance executes the operation on the resource.
-
When the operation is complete, the framework releases the connector instance back into the pool. No
dispose()
method is called.
The following illustration shows the initialization process for a stateless, poolable connector, and references the numbered steps in the preceding list.
Instantiate a stateful, non-poolable connector
The third connector type has a stateful configuration, and cannot be pooled. A stateful, non-poolable connector is instantiated as follows:
-
The ICF framework creates a new configuration instance, initializes it with its configuration properties, and stores it in the connector facade, before any operations are called.
This single configuration instance is shared between multiple threads. The framework does not guarantee isolation, so connector developers must ensure that their implementation is thread-safe.
-
The application calls an operation (for example, CREATE) on the connector facade.
-
The ICF framework creates a new connector instance, and calls the
init()
method on that connector instance, with the stored configuration. The framework initializes the connector with the single configuration instance stored within the connector facade. -
The framework executes the operation (for example, CREATE) on the connector instance.
-
The connector instance executes the operation on the resource.
-
The framework calls the
dispose()
method to release all resources that the connector instance was using.Note that the customized config instance remains in the connector facade, and is reused for the next operation.
The following illustration shows the initialization process for a non-poolable connector, with a stateful configuration. The illustration references the numbered steps in the preceding list.
Instantiate a stateful, poolable connector
The fourth connector type has a stateful configuration, and can be pooled. A stateful, poolable connector is instantiated as follows:
-
The ICF framework creates a new configuration instance, initializes it with its configuration properties, and stores it in the connector facade, before any operations are called.
This single configuration instance is shared between multiple threads. The framework does not guarantee isolation, so connector developers must ensure that their implementation is thread-safe.
-
The application calls an operation (for example, CREATE) on the connector facade.
-
The framework calls on the object pool, to borrow a live connector instance to execute the operation.
If the object pool has an idle connector instance available, the framework borrows that one instance (step 5a in the illustration that follows).
The framework calls the
checkAlive
method on the customized connector instance with its configuration, to check if the instance that was borrowed from the pool is still alive, and ready to execute the operation. If the instance is no longer alive and ready, the framework disposes of the instance and borrows another one.The thread that borrows the object has exclusive access to that connector instance; that is, it is thread-safe.
-
If the object pool has no idle connector instances, the pool creates a new connector instance.
-
The framework initializes the borrowed connector instance, with the stored configuration.
-
The framework executes the operation (for example, CREATE) on the connector instance.
-
The connector instance executes the operation on the resource.
-
When the operation is complete, the framework releases the connector instance back into the pool. No
dispose()
method is called.
The following illustration shows the initialization process for a stateful, poolable connector, and references the numbered steps in the preceding list.
OpenICF SPI
This chapter describes the ICF SPI, which lets you create connectors that are compatible with the ICF framework.
The SPI includes a number of interfaces, but you need only implement those that are supported by the target resource to which you are connecting. For information about how to get started with writing connectors, refer to Java connectors and Scripted connectors with Groovy.
The order in which you implement your connector is as follows:
-
Decide on the connector type (refer to Connector types).
-
Implement the configuration interface (refer to Configuration interface).
-
Implement the connector interface (refer to Connector interface).
-
Implement the operation interfaces (refer to Operation interfaces).
Connector types
ICF supports multiple connector types, based on the implementation of the connector
interface, and the configuration
interface. These two interfaces determine whether the connector can be pooled, and whether its configuration is stateful. Before you begin developing your connector, decide on the connector type, based on the system to which you are connecting. For an overview of how the ICF framework manages each connector type, refer to Connector instance management.
This section outlines the different connector types.
- Connector
-
The basic connector is a non-poolable connector. Each operation is executed on a new instance of the connector. ICF creates a new instance of the Connector class and uses a new or existing instance of the connector configuration to initialize the instance before the operation is executed. After the execution, ICF disposes of the connector instance.
- Poolable Connector
-
Before an operation is executed, an existing connector instance is pulled from the Connector Pool. If there is no existing instance, a new instance is created. After the operation execution, the Connector instance is released and placed back into pool.
The ICF framework pools instances of a poolable connector, rather than pooling connections within the connector.
- Configuration
-
For a basic (non-stateful) configuration, each time the configuration is used (when an operation is validated or a new connector instance is initialized, a new Configuration instance is created and configured with the Configuration properties.
- Stateful Configuration
-
With a stateful configuration, the configuration instance is created only once and is used until the Facade or Connector Pool that is associated with the Configuration is disposed of.
The following table illustrates how these elements combine to determine the connector type.
Connector | Poolable Connector | |
---|---|---|
Configuration |
Entirely stateless combination. A new Configuration and Connector instance are created for each operation. |
Connector initialization is an expensive operation, so it is preferable to keep connector instances in a pool. A new configuration is required only when a new connector instance is added to the pool. |
Stateful Configuration |
The configuration can be used to make the heavy resource initialization. The less intensive connector instance can then execute the operation. |
The configuration must be shared between the instances in the same pool and the connector initialization is expensive. |
For detailed information on how the ICF framework manages each of these connector types, refer to Connector instance management.
Configuration interface
The ICF connector framework uses the configuration interface implementation to build the configuration properties inside the API configuration.
The configuration interface implementation includes the required information to enable the connector to connect to the target system, and to perform its operations. The configuration interface implements getters and setters for each of its defined properties. It also provides a validate method that your application can use to check whether all the required properties are available, and valid, before passing them to the connector.
The configuration interface has three methods:
-
setConnectorMessages(ConnectorMessages messages)
sets the message catalog instance, and lets the connector provide localized messages.The message catalog is defined in the file
Messages.properties
, and can be localized as required by appending the locale to the file name, for example,Messages_fr.properties
. For more information on the message catalog, refer to Connector messages object. -
getConnectorMessages()
returns the message catalog that is set by setConnectorMessages(ConnectorMessages). -
validate()
checks that all the required properties have been set and that their values are valid.The purpose of this method is to test that the configuration that the application provides to your connector is valid.
Each property that is declared is not necessarily required. If a property is required, it must be included in the ConfigurationProperty
annotation.
The ConfigurationProperty
annotation (Java) or attribute (.NET) lets you add custom meta information to properties. The ICF framework scans the meta information and collects this information to build the ConfigurationProperties
object inside the APIConfiguration
. The following meta information can be provided:
Element | Description | Implementation in Java | Implementation in C# |
---|---|---|---|
order |
The order in which this property is displayed |
||
helpMessageKey |
Lets you change the default help message key |
|
|
displayMessageKey |
Lets you change the default display message key |
|
|
groupMessageKey |
Lets you change the default group message key |
|
|
confidential |
Indicates that this is a confidential property and that its value should be encrypted by the application when persisted |
||
required |
Boolean, indicates whether the property is required |
||
operations |
The array of operations that require this property |
The following examples show how the meta information is provided, in both Java and C#.
-
Java
-
C#
public class SampleConfiguration extends AbstractConfiguration {
/**

*/
public void validate() {
}
@ConfigurationProperty(
order = 1,

OperationTypes = new[] { typeof(AuthenticateOp) })
]
public String PasswordFieldName
{ get; set; }
public override void Validate()
{
throw new NotImplementedException();
}
}

Java
-
C#
public class SampleConfiguration extends AbstractConfiguration
implements StatefulConfiguration {
/**

}
public class ActiveDirectoryConfiguration : AbstractConfiguration,
StatefulConfiguration
{
public override void Validate()
{
throw new NotImplementedException();
}
public void Release()
{
throw new NotImplementedException();
}
}
Validate operation
The validate operation validates the connector configuration. A valid configuration is one that is ready to be used by the connector.
A configuration that is ready, has the following characteristics:
-
It is complete, that is, all required properties are present and have values.
-
All property values are well-formed, that is, they are in the expected range and have the expected format.
ValidateApiOp
The validate operation returns a ConfigurationException
in the following situations:
-
The Framework version is not compatible with the connector.
-
The connector does not have the required attributes in
MANIFEST.MF
. -
The
ConfigurationProperties
cannot be merged into the configuration.
@Test
public void ValidateTest() {
logger.info("Running Validate Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
facade.validate();
}
Validate SPI implementation
The validate()
method of the configuration operation must return one of the following:
-
RuntimeException
if the configuration is not valid. -
NullPointerException
if a required configuration property is null. -
IllegalArgumentException
if a required configuration property is blank.
public void validate() {
if (StringUtil.isBlank(host)) {
throw new IllegalArgumentException("Host User cannot be null or empty.");
}
Assertions.blankCheck(remoteUser, "remoteUser");
Assertions.nullCheck(password, "password");
}
Supported configuration types
The ICF framework supports a limited number of configuration property types. This limitation is necessary, because ICF must serialise and deserialize the configuration property values when sending them over the network.
You can use any of the following types, or an array of these types. Lists of types are not supported.
String.class long.class Long.class char.class Character.class double.class Double.class float.class Float.class int.class Integer.class boolean.class Boolean.class URI.class File.class GuardedByteArray.class GuardedString.class Script.class
typeof(string), typeof(long), typeof(long?), typeof(char), typeof(char?), typeof(double), typeof(double?), typeof(float), typeof(float?), typeof(int), typeof(int?), typeof(bool), typeof(bool?), typeof(Uri), typeof(FileName), typeof(GuardedByteArray), typeof(GuardedString), typeof(Script)
The framework introspects the implemented configuration class and adds all properties that have a set/get
method to the ConfigurationProperties
object.
The ConfigurationClass
annotation (Java) or attribute (.NET) provides additional information to the ICF framework about the configuration class. The following information is provided:
Element | Description |
---|---|
privateProperty |
If this is set, the property is hidden from the application, and the application cannot set the property through the |
skipUnsupported |
If the type of an added property is not supported, the framework throws an exception. To avoid the exception, set the value of |

C#
@ConfigurationClass(ignore = { "privateProperty", "internalProperty" }, skipUnsupported = true)
[ConfigurationClass(Ignore = { "privateProperty", "internalProperty" }, SkipUnsupported = true)]
Connector interface
The connector interface declares a connector, and manages its life cycle. You must implement the connector
interface. A typical connector lifecycle is as follows:
-
The connector creates a connection to the target system.
-
Any operations implemented in the connector are called.
-
The connector discards the connection and disposes of any resources it has used.
The connector
interface has only three methods:
-
init(Configuration)
initializes the connector with its configuration -
getConfiguration()
returns the configuration that was passed toinit(Configuration)
-
dispose()
disposes of any resources that the connector uses.
The ConnectorClass
, which is the implementation of the connector interface, must have the ConnectorClass
annotation (Java) or attribute (.NET) so that the ICF framework can find the connector class. The following table shows the elements within the connector class.
Element | Description |
---|---|
configurationClass |
The configuration class for the connector. |
displayNameKey |
A key in the message catalog that holds a human readable name for the connector. |
categoryKey |
The category to which the connector belongs, such as LDAP, or DB. |
messageCatalogPaths |
The resource path(s) to the message catalog. If multiple paths are provided, the message catalogs are collated. By default, if no path is specified, the |
The following examples show the connector interface implementation, in Java and C#.

displayNameKey = "Sample.connector.display",
configurationClass = SampleConfiguration.class)
public class SampleConnector implements Connector...
[ConnectorClass(
"connector_displayName",
typeof (SampleConfiguration)
]
public class SampleConnector : Connector ...
Implement a poolable connector interface
Certain connectors support the ability to be pooled. For a pooled connector, ICF maintains a pool of connector instances and reuses these instances for multiple provisioning and reconciliation operations. When an operation must be executed, an existing connector instance is taken from the connector pool. If no connector instance exists, a new instance is initialized. When the operation has been executed, the connector instance is released back into the connector pool, ready to be used for a subsequent operation.
For an unpooled connector, a new connector instance is initialized for every operation. When the operation has been executed, ICF disposes of the connector instance. Because the initialization of a connector is an expensive operation, reducing the number of connector initializations can substantially improve performance.
The following connection pooling configuration parameters can be set:
- maxObjects
-
The maximum number of connector instances in the pool (both idle and active). The default value is 10 instances.
- maxIdle
-
The maximum number of idle connector instances in the pool. The default value is 10 idle instances.
- maxWait
-
The maximum period to wait for a free connector instance to become available before failing. The default period is 150000 milliseconds, or 15 seconds.
- minEvictableIdleTimeMillis
-
The minimum period to wait before evicting an idle connector instance from the pool. The default period is 120000 milliseconds, or 2 minutes.
A connection pool cleaner thread runs every minute and closes connections whose
lastUsed
time is larger than theminEvictableIdleTimeMillis
. - minIdle
-
The minimum number of idle connector instances in the pool. The default value is 1 instance.
A PoolableConnector
extends the connector interface with the checkAlive()
method. You should use a PoolableConnector
when the init(Configuration)
method is so expensive that it is worth keeping the connector instance in a pool and reusing it between operations. When an existing connector instance is pooled, the framework calls the checkAlive()
method. If this method throws an error, the framework discards it from the pool and obtains another instance, or creates a new connector instance and calls the init()
method. The checkAlive()
method is used to make sure that the instance in the pool is still operational.
Operation interfaces
The SPI provides several operations. The subset of operations that you implement will depend on the target resource to which you are connecting. Each operation interface defines an action that the connector can perform on the target resource.
The following sections describe the operation interfaces that are provided by the SPI, and provide examples of how they can be implemented in your connector. The sections include the API- and SPI-level rules for each operation.
Authenticate operation
The authenticate operation authenticates an object on the target system, based on two parameters, usually a unique identifier (username) and a password. If possible, your connector should try to authenticate these credentials natively.
If authentication fails, the connector should throw a runtime exception. The exception must be an IllegalArgumentException
or, if a native exception is available and is of type RuntimeException
, that native runtime exception. If the native exception is not a RuntimeException
, it should be wrapped in a RuntimeException
, and then thrown.
The exception should provide as much detail as possible for logging problems and failed authentication attempts. Several exceptions are provided in the exceptions
package, for this purpose. For example, one of the most common authentication exceptions is the InvalidPasswordException
.
For more information about the common exceptions provided in the OpenICF framework, refer to Common exceptions.
Use the ICF authenticate operation
This section shows how your application can use the framework’s authentication
operation, and how to write a unit test for this operation, when you are developing your connector.
The authentication
operation throws a RuntimeException
if the credentials do not pass authentication, otherwise returns the UID
.
@Test
public void authenticateTest() {
logger.info("Running Authentication Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
Uid uid =
facade.authenticate(ObjectClass.ACCOUNT, "username", new GuardedString("Passw0rd"
.toCharArray()), builder.build());
Assert.assertEquals(uid.getUidValue(), "username");
}
Implement the authenticate operation
To implement the authenticate
operation in your connector, add the AuthenticateOp
interface to your connector class, for example:
@ConnectorClass(
displayNameKey = "Sample.connector.display",
configurationClass = SampleConfiguration.class)
public class SampleConnector implements Connector, AuthenticateOp...
For more information, refer to the AuthenticateOp JavaDoc.
The SPI provides the following detailed exceptions:
-
UnknownUidException - the UID does not exist on the resource.
(org.identityconnectors.framework.common.exceptions.UnknownUidException)
-
ConnectorSecurityException - base exception for all security-related exceptions.
(org.identityconnectors.framework.common.exceptions.ConnectorSecurityException)
-
InvalidCredentialException - generic invalid credential exception that should be used if the specific error cannot be obtained.
(org.identityconnectors.framework.common.exceptions.UnknownUidException)
-
InvalidPasswordException - the password provided is incorrect.
(org.identityconnectors.framework.common.exceptions.InvalidPasswordException)
-
PasswordExpiredException - the password is correct, but has expired.
(org.identityconnectors.framework.common.exceptions.PasswordExpiredException)
-
PermissionDeniedException - the user can be identified but does not have permission to authenticate.
(org.identityconnectors.framework.common.exceptions.PermissionDeniedException)
public Uid authenticate(final ObjectClass objectClass, final String userName,
final GuardedString password, final OperationOptions options) {
if (ObjectClass.ACCOUNT.equals(objectClass)) {
return new Uid(userName);
} else {
logger.warn("Authenticate of type {0} is not supported", configuration
.getConnectorMessages().format(objectClass.getDisplayNameKey(),
objectClass.getObjectClassValue()));
throw new UnsupportedOperationException("Authenticate of type"
+ objectClass.getObjectClassValue() + " is not supported");
}
}
Create operation
The create operation interface enables the connector to create objects on the target system. The operation includes one method (create()
). The method takes an ObjectClass
, and any provided attributes, and creates the object and its UID. The connector must return the UID so that the caller can refer to the created object.
The connector should make a best effort to create the object, and should throw an informative RuntimeException
, indicating to the caller why the operation could not be completed. Defaults can be used for any required attributes, as long as the defaults are documented.
The UID is never passed in with the attribute set for this method. If the resource supports a mutable UID, you can create a resource-specific attribute for the ID, such as unix_uid
.
If the create
operation is only partially successful, the connector should attempt to roll back the partial change. If the target system does not allow this, the connector should report the partial success of the create operation and throw a RetryableException
. For example:
public static RetryableException wrap(final String message, final Uid uid) {
return new RetryableException(message, new AlreadyExistsException().initUid(Assertions
.nullChecked(uid, "Uid")));
}
Use the ICF create operation
The following exceptions are thrown by the Create API operation:
-
IllegalArgumentException
- ifObjectClass
is missing, or if elements of the set produce duplicate values ofAttribute#getName()
-
NullPointerException
- if thecreateAttributes
parameter isnull
-
RuntimeException
- if theConnector
SPI throws a native exception
@Test
public void createTest() {
logger.info("Running Create Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
Set<Attribute> createAttributes = new HashSet<Attribute>();
createAttributes.add(new Name("Foo"));
createAttributes.add(AttributeBuilder.buildPassword("Password".toCharArray()));
createAttributes.add(AttributeBuilder.buildEnabled(true));
Uid uid = facade.create(ObjectClass.ACCOUNT, createAttributes, builder.build());
Assert.assertEquals(uid.getUidValue(), "foo");
}
Implement the create operation
The SPI provides the following detailed exceptions:
-
UnsupportedOperationException
- the create operation is not supported for the specified object class -
InvalidAttributeValueException
- a required attribute is missing, an attribute is present that cannot be created, or a provided attribute has an invalid value -
AlreadyExistsException
- an object with the specifiedName
already exits on the target system -
PermissionDeniedException
- the target resource will not allow the connector to perform the specified operation -
ConnectorIOException, ConnectionBrokenException, ConnectionFailedException
- a problem as occurred with the connection -
RuntimeException
- thrown if anything else goes wrong. You should try to throw a native exception in this case.
public Uid create(final ObjectClass objectClass, final Set<Attribute> createAttributes,
final OperationOptions options) {
if (ObjectClass.ACCOUNT.equals(objectClass) || ObjectClass.GROUP.equals(objectClass)) {
Name name = AttributeUtil.getNameFromAttributes(createAttributes);
if (name != null) {
// do real create here
return new Uid(AttributeUtil.getStringValue(name).toLowerCase());
} else {
throw new InvalidAttributeValueException("Name attribute is required");
}
} else {
logger.warn("Delete of type {0} is not supported", configuration.getConnectorMessages()
.format(objectClass.getDisplayNameKey(), objectClass.getObjectClassValue()));
throw new UnsupportedOperationException("Delete of type"
+ objectClass.getObjectClassValue() + " is not supported");
}
}
Delete operation
The delete operation interface enables the connector to delete an object on the target system. The operation includes one method (delete()
). The method takes an ObjectClass
, a Uid
, and any operation options.
The connector should call the native delete methods to remove the object, specified by its unique ID.
Use the ICF delete operation
The following exceptions are thrown by the Delete API operation:
-
UnknownUidException
- the UID does not exist on the resource
@Test
public void deleteTest() {
logger.info("Running Delete Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
facade.delete(ObjectClass.ACCOUNT, new Uid("username"), builder.build());
}
Implement the delete operation
public void delete(final ObjectClass objectClass, final Uid uid, final OperationOptions options) {
if (ObjectClass.ACCOUNT.equals(objectClass) || ObjectClass.GROUP.equals(objectClass)) {
// do real delete here
} else {
logger.warn("Delete of type {0} is not supported", configuration.getConnectorMessages()
.format(objectClass.getDisplayNameKey(), objectClass.getObjectClassValue()));
throw new UnsupportedOperationException("Delete of type"
+ objectClass.getObjectClassValue() + " is not supported");
}
}
Resolve username operation
The resolve username operation enables the connector to resolve an object to its UID, based on its username. This operation is similar to the simple authentication operation. However, the resolve username operation does not include a password parameter, and does not attempt to authenticate the credentials. Instead, it returns the UID that corresponds to the supplied username.
The implementation must, however, validate the username (that is, the connector must throw an exception if the username does not correspond to an existing object). If the username validation fails, the the connector should throw a runtime exception, either an IllegalArgumentException
or, if a native exception is available and is of type RuntimeException
, simply throw that exception. If the native exception is not a RuntimeException
, it should be wrapped in a RuntimeException
, and then thrown.
The exception should provide as much detail as possible for logging problems and failed attempts. Several exceptions are provided in the exceptions
package, for this purpose. For example, one of the most common exceptions is the UnknownUidException
.
Use the ICF resolve username operation
The operation throws a RuntimeException
if the username validation fails, otherwise returns the UID
.
@Test
public void resolveUsernameTest() {
logger.info("Running ResolveUsername Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
Uid uid = facade.resolveUsername(ObjectClass.ACCOUNT, "username", builder.build());
Assert.assertEquals(uid.getUidValue(), "username");
}
Implement the resolve username operation
The SPI provides the following detailed exceptions:
-
UnknownUidException - the UID does not exist on the resource
public Uid resolveUsername(final ObjectClass objectClass, final String userName,
final OperationOptions options) {
if (ObjectClass.ACCOUNT.equals(objectClass)) {
return new Uid(userName);
} else {
logger.warn("ResolveUsername of type {0} is not supported", configuration
.getConnectorMessages().format(objectClass.getDisplayNameKey(),
objectClass.getObjectClassValue()));
throw new UnsupportedOperationException("ResolveUsername of type"
+ objectClass.getObjectClassValue() + " is not supported");
}
}
Schema operation
The Schema Operation interface enables the connector to describe the types of objects that it can handle on the target system, and the operations and options that the connector supports for each object type.
The operation has one method, schema()
, which returns the types of objects on the target system that the connector supports. The method should return the object class name, its description, and a set of attribute definitions.
The implementation of this operation includes a mapping between the native object class and the corresponding connector object. The special Uid
attribute should not be returned, because it is not a true attribute of the object, but a reference to it. For more information about special attributes in ICF, refer to ICF Special Attributes.
If your resource object class has a writable unique ID attribute that is different to its Name
, your schema should contain a resource-specific attribute that represents this unique ID. For example, a Unix account object might contain a unix_uid
.
Use the ICF schema operation
@Test
public void schemaTest() {
logger.info("Running Schema Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
Schema schema = facade.schema();
Assert.assertNotNull(schema.findObjectClassInfo(ObjectClass.ACCOUNT_NAME));
}
Implement the schema operation
public Schema schema() {
if (null == schema) {
final SchemaBuilder builder = new SchemaBuilder(BasicConnector.class);
// Account
ObjectClassInfoBuilder accountInfoBuilder = new ObjectClassInfoBuilder();
accountInfoBuilder.addAttributeInfo(Name.INFO);
accountInfoBuilder.addAttributeInfo(OperationalAttributeInfos.PASSWORD);
accountInfoBuilder.addAttributeInfo(PredefinedAttributeInfos.GROUPS);
accountInfoBuilder.addAttributeInfo(AttributeInfoBuilder.build("firstName"));
accountInfoBuilder.addAttributeInfo(AttributeInfoBuilder.define("lastName")
.setRequired(true).build());
builder.defineObjectClass(accountInfoBuilder.build());
// Group
ObjectClassInfoBuilder groupInfoBuilder = new ObjectClassInfoBuilder();
groupInfoBuilder.setType(ObjectClass.GROUP_NAME);
groupInfoBuilder.addAttributeInfo(Name.INFO);
groupInfoBuilder.addAttributeInfo(PredefinedAttributeInfos.DESCRIPTION);
groupInfoBuilder.addAttributeInfo(AttributeInfoBuilder.define("members").setCreatable(
false).setUpdateable(false).setMultiValued(true).build());
// Only the CRUD operations
builder.defineObjectClass(groupInfoBuilder.build(), CreateOp.class, SearchOp.class,
UpdateOp.class, DeleteOp.class);
// Operation Options
builder.defineOperationOption(OperationOptionInfoBuilder.buildAttributesToGet(),
SearchOp.class);
// Support paged Search
builder.defineOperationOption(OperationOptionInfoBuilder.buildPageSize(),
SearchOp.class);
builder.defineOperationOption(OperationOptionInfoBuilder.buildPagedResultsCookie(),
SearchOp.class);
// Support to execute operation with provided credentials
builder.defineOperationOption(OperationOptionInfoBuilder.buildRunWithUser());
builder.defineOperationOption(OperationOptionInfoBuilder.buildRunWithPassword());
schema = builder.build();
}
return schema;
}
Script on connector operation
The script on connector operation runs a script in the environment of the connector. This is different to the script on resource operation, which runs a script on the target resource that the connector manages.
The corresponding API operation (scriptOnConnectorApiOp
) provides a minimum contract to which the connector must adhere. (Refer to the javadoc for more information). If you do not implement the scriptOnConnector
interface in your connector, the framework provides a default implementation. If you intend your connector to provide more to the script than what is required by this minimum contract, you must implement the scriptOnConnectorOp
interface.
Use the ICF script on connector operation
The API operation allows an application to run a script in the context of any connector.
This operation runs the script in the same JVM or .Net Runtime as the connector. That is, if you are using a local framework, the script runs in your JVM. If you are connected to a remote framework, the script runs in the remote JVM or .Net Runtime.
@Test
public void runScriptOnConnectorTest() {
logger.info("Running RunScriptOnConnector Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
builder.setRunAsUser("admin");
builder.setRunWithPassword(new GuardedString("Passw0rd".toCharArray()));
final ScriptContextBuilder scriptBuilder =
new ScriptContextBuilder("Groovy", "return argument");
scriptBuilder.addScriptArgument("argument", "value");
Object result = facade.runScriptOnConnector(scriptBuilder.build(), builder.build());
Assert.assertEquals(result, "value");
}
Implement the script on connector operation
The scriptOnConnector
SPI operation takes the following parameters:
-
request
- the script and the arguments to be run -
options
- additional options that control how the script is run
The operation returns the result of the script. The return type must be a type that the framework supports for serialization. Refer to the ObjectSerializerFactory javadoc for a list of supported return types.
public Object runScriptOnConnector(ScriptContext request, OperationOptions options) {
final ScriptExecutorFactory factory =
ScriptExecutorFactory.newInstance(request.getScriptLanguage());
final ScriptExecutor executor =
factory.newScriptExecutor(getClass().getClassLoader(), request.getScriptText(),
true);
if (StringUtil.isNotBlank(options.getRunAsUser())) {
String password = SecurityUtil.decrypt(options.getRunWithPassword());
// Use these to execute the script with these credentials
}
try {
return executor.execute(request.getScriptArguments());
} catch (Throwable e) {
logger.warn(e, "Failed to execute Script");
throw ConnectorException.wrap(e);
}
}
Script on resource operation
The script on resource operation runs a script directly on the target resource (unlike the Script on connector operation, which runs a script in the context of a specific connector.)
Implement this interface if your connector intends to support the ScriptOnResourceApiOp
API operation. If your connector implements this interface, you must document the script languages that the connector supports, as well as any supported OperationOptions
.
Use the ICF script on resource operation
The contract at the API level is intentionally very loose. Each connector decides what script languages it supports, what running a script on a target resource actually means, and what script options (if any) the connector supports.
@Test
public void runScriptOnResourceTest() {
logger.info("Running RunScriptOnResource Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
builder.setRunAsUser("admin");
builder.setRunWithPassword(new GuardedString("Passw0rd".toCharArray()));
final ScriptContextBuilder scriptBuilder = new ScriptContextBuilder("bash", "whoami");
Object result = facade.runScriptOnResource(scriptBuilder.build(), builder.build());
Assert.assertEquals(result, "admin");
}
Implement the script on resource operation
The scriptOnResource
SPI operation takes the following parameters:
-
request
- the script and the arguments to be run -
options
- additional options that control how the script is run
The operation returns the result of the script. The return type must be a type that the framework supports for serialization. Refer to the ObjectSerializerFactory javadoc for a list of supported return types.
public Object runScriptOnResource(ScriptContext request, OperationOptions options) {
try {
// Execute the script on remote resource
if (StringUtil.isNotBlank(options.getRunAsUser())) {
String password = SecurityUtil.decrypt(options.getRunWithPassword());
// Use these to execute the script with these credentials
return options.getRunAsUser();
}
throw new UnknownHostException("Failed to connect to remote SSH");
} catch (Throwable e) {
logger.warn(e, "Failed to execute Script");
throw ConnectorException.wrap(e);
}
}
Search operation
The search operation enables the connector to search for objects on the target system.
The ICF framework handles searches as follows:
-
The application sends a query, with a search filter, to the OpenICF framework.
-
The framework submits the query, with the filter, to the connector.
-
The connector implements the
createFilterTranslator()
method to obtain aFilterTranslator
object. -
The framework then uses this
FilterTranslator
object to transform the filter to a format that theexecuteQuery()
method expects.
You can implement the FilterTranslator
object in two ways:
-
The
FilterTranslator
translates the original filter into one or more native queries.The framework then calls the
executeQuery()
method for each native query. -
The
FilterTranslator
does not modify the original filter.The framework then calls the
executeQuery()
method with the original ICF filter.Using this second approach enables your connector to distinguish between a search and a get operation and to benefit from the visitor design pattern.
Based on the resultsHandlerConfiguration
, the OpenICF framework can perform additional filtering on the returning results. For more information on the resultsHandlerConfiguration
, refer to Configure How Results Are Handled.
The connector facade calls the executeQuery
method once for each native query that the filter translator produces. If the filter translator produces more than one native query, the connector facade merges the results from each query and eliminates any duplicates.
Note that this implies an in-memory data structure that holds a set of UID values. Memory usage, in the event of multiple queries, will be O(N) where N is the number of results. It is therefore important that the filter translator for the connector implement OR
operators, if possible.
Whether the application calls a get
API operation, or a search
API operation, the ICF framework translates that request to a search
request on the connector.
Use the ICF get operation
The GetApiOp
returns null
when the UID does not exist on the resource.
@Test
public void getObjectTest() {
logger.info("Running GetObject Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
builder.setAttributesToGet(Name.NAME);

final OperationOptionsBuilder builder = new OperationOptionsBuilder();
builder.setPageSize(10);

SearchResult result =
facade.search(ObjectClass.ACCOUNT, FilterBuilder.equalTo(new Name("Foo")), handler,
builder.build());
Assert.assertEquals(result.getPagedResultsCookie(), "0");
Assert.assertEquals(((ToListResultsHandler) handler).getObjects().size(), 1);
}
Implement the search operation
public FilterTranslator<String> createFilterTranslator(ObjectClass objectClass,
OperationOptions options) {
return new BasicFilterTranslator();
}
public void executeQuery(ObjectClass objectClass, String query, ResultsHandler handler,
OperationOptions options) {
final ConnectorObjectBuilder builder = new ConnectorObjectBuilder();
builder.setUid("3f50eca0-f5e9-11e3-a3ac-0800200c9a66");
builder.setName("Foo");
builder.addAttribute(AttributeBuilder.buildEnabled(true));
for (ConnectorObject connectorObject : CollectionUtil.newSet(builder.build())) {
if (!handler.handle(connectorObject)) {
// Stop iterating because the handler stopped processing
break;
}
}
if (options.getPageSize() != null && 0 < options.getPageSize()) {
logger.info("Paged Search was requested");
((SearchResultsHandler) handler).handleResult(new SearchResult("0", 0));
}
}
Sync operation
The sync operation polls the target system for synchronization events, that is, native changes to target objects.
The operation has two methods:
-
sync()
- request synchronization events from the target systemThis method calls the specified handler, once, to pass back each matching synchronization event. When the method returns, it will no longer invoke the specified handler.
-
getLatestSyncToken()
- returns the token corresponding to the most recent synchronization event

throw new UnsupportedOperationException("Sync of type"

}
}
Test operation
The test operation tests the connector configuration. Unlike validation, testing a configuration verifies that every part of the environment that is referred to by the configuration is available. The operation therefore validates that the connection details that are provided in the configuration are accurate, and that the backend is accessible when using them.
For example, the connector might make a physical connection to the host that is specified in the configuration, to check that it exists and that the credentials supplied in the configuration are valid.
The test operation can be invoked before the configuration has been validated, or can validate the configuration before testing it.
Use the ICF test operation
At the API level, the test operation throws a RuntimeException
if the configuration is not valid, or if the test fails. Your connector implementation should throw the most specific exception available. When no specific exception is available, your connector implementation should throw a ConnectorException
.
@Test
public void testTest() {
logger.info("Running Test Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
facade.test();
}
Update operation
If your connector will allow an authorized caller to update (modify or replace) objects on the target system, you must implement either the update operation, or the Update attribute values operation. At the API level, update operation calls either the UpdateOp
or the UpdateAttributeValuesOp
, depending on what you have implemented.
The update operation is somewhat simpler to implement than the Update attribute values operation, because the update attribute values operation must handle any type of update that the caller might specify. However a true implementation of the update attribute values operation offers better performance and atomicity semantics.
Use the ICF update operation
At the API level, the update operation returns an UnknownUidException
if the UID does not exist on the target system resource and if the connector does not implement the Update attribute values operation interface.
@Test
public void updateTest() {
logger.info("Running Update Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
Set<Attribute> updateAttributes = new HashSet<Attribute>();
updateAttributes.add(new Name("Foo"));
Uid uid = facade.update(ObjectClass.ACCOUNT, new Uid("Foo"), updateAttributes, builder
.build());
Assert.assertEquals(uid.getUidValue(), "foo");
}
Implement the update operation
At the SPI level, the update operation returns an UnknownUidException
if the UID does not exist on the target system.
public Uid update(ObjectClass objectClass, Uid uid, Set<Attribute> replaceAttributes,
OperationOptions options) {
AttributesAccessor attributesAccessor = new AttributesAccessor(replaceAttributes);
Name newName = attributesAccessor.getName();
Uid uidAfterUpdate = uid;
if (newName != null) {
logger.info("Rename the object {0}:{1} to {2}", objectClass.getObjectClassValue(), uid
.getUidValue(), newName.getNameValue());
uidAfterUpdate = new Uid(newName.getNameValue().toLowerCase());
}
if (ObjectClass.ACCOUNT.equals(objectClass)) {
} else if (ObjectClass.GROUP.is(objectClass.getObjectClassValue())) {
if (attributesAccessor.hasAttribute("members")) {
throw new InvalidAttributeValueException(
"Requested to update a read only attribute");
}
} else {
logger.warn("Update of type {0} is not supported", configuration.getConnectorMessages()
.format(objectClass.getDisplayNameKey(), objectClass.getObjectClassValue()));
throw new UnsupportedOperationException("Update of type"
+ objectClass.getObjectClassValue() + " is not supported");
}
return uidAfterUpdate;
}
Approaches for deleting attributes and attribute values
If the target resource to which you are connecting supports the removal of attributes, you can implement the removal in several ways. All the samples in this document assume the following syntax rules for deleting attributes or removing their values.
Update | Syntax rule | Query filter |
---|---|---|
Set an empty attribute value |
|
|
Set an attribute value to null |
|
|
Removing an attribute |
|
|
Update attribute values operation
The update attribute values operation is an advanced implementation of the update operation. You should implement this operation if you want your connector to offer better performance and atomicity for the following methods:
-
UpdateApiOp.addAttributeValues(ObjectClass, Uid, Set, OperationOptions)
-
UpdateApiOp.removeAttributeValues(ObjectClass, Uid, Set, OperationOptions)
@Test
public void addAttributeValuesTest() {
logger.info("Running AddAttributeValues Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
Set<Attribute> updateAttributes = new HashSet<Attribute>();
// add 'group2' to existing groups
updateAttributes.add(AttributeBuilder.build(PredefinedAttributes.GROUPS_NAME, "group2"));
Uid uid =
facade.addAttributeValues(ObjectClass.ACCOUNT, new Uid("Foo"), updateAttributes,
builder.build());
Assert.assertEquals(uid.getUidValue(), "foo");
}
@Test
public void removeAttributeValuesTest() {
logger.info("Running RemoveAttributeValues Test");
final ConnectorFacade facade = createConnectorFacade(BasicConnector.class, null);
final OperationOptionsBuilder builder = new OperationOptionsBuilder();
Set<Attribute> updateAttributes = new HashSet<Attribute>();
// remove 'group2' from existing groups
updateAttributes.add(AttributeBuilder.build(PredefinedAttributes.GROUPS_NAME, "group2"));
Uid uid =
facade.removeAttributeValues(ObjectClass.ACCOUNT, new Uid("Foo"), updateAttributes,
builder.build());
Assert.assertEquals(uid.getUidValue(), "foo");
}
Implement the update attribute values operation
At the SPI level, the update attribute values operation returns an UnknownUidException
when the UID does not exist on the resource.
public Uid addAttributeValues(ObjectClass objectClass, Uid uid, Set<Attribute> valuesToAdd,
OperationOptions options) {
return uid;
}
public Uid removeAttributeValues(ObjectClass objectClass, Uid uid,
Set<Attribute> valuesToRemove, OperationOptions options) {
return uid;
}
Common exceptions
The following sections describe the commonly used exceptions that can be thrown, depending on the operation.
- AlreadyExistsException
-
The
AlreadyExistsException
is thrown if a create operation attempts to create an object that exists prior to the method execution, or if an update operation attempts to rename an object to that exists prior to the method execution.
- ConfigurationException
-
A
ConfigurationException
is thrown if a configuration problem is encountered when the connector bundles are loaded. AConfigurationException
can also be thrown during validation operations in the SPI.
- ConnectionBrokenException
-
A
ConnectionBrokenException
is thrown when a connection to a target resource instance fails during an operation. An instance of theConnectionBrokenException
generally wraps the native exception (or describes the native error) that is returned by the target resource.
- ConnectionFailedException
-
A
ConnectionFailedException
is thrown when a connector cannot reach the target resource. An instance of theConnectionFailedException
generally wraps the native exception (or describes the native error) that is returned by the target resource.
- ConnectorException
-
This is the base exception for the connector framework. The framework only throws exceptions that extend
ConnectorException
.
- ConnectorIOException
-
This is the base exception for all Input-Output (I/O-related) exceptions, including instance connection failure, socket error, and so forth.
- ConnectorSecurityException
-
This is the base exception for all security-related exceptions.
- InvalidAttributeValueException
-
An
InvalidAttributeValueException
is thrown when an attempt is made to add to an attribute a value that conflicts with the attribute’s schema definition. This might happen, for example, in the following situations:-
The connector attempts to add an attribute with no value when the attribute is required to have at least one value.
-
The connector attempts to add more than one value to a single valued-attribute.
-
The connector attempts to add a value that conflicts with the attribute type.
-
The connector attempts to add a value that conflicts with the attribute syntax.
-
- InvalidCredentialException
-
An
InvalidCredentialException
indicates that user authentication has failed. This exception is thrown by the connector when authentication fails, and when the specific reason for the failure is not known. For example, the connector might throw this exception if a user has entered an incorrect password, or username.
- InvalidPasswordException
-
An
InvalidPasswordException
is thrown when a password credential is invalid.
- OperationTimeoutException
-
An
OperationTimeoutException
is thrown when an operation times out. The framework cancels an operation when the corresponding method has been executing for longer than the limit specified inAPIConfiguration
.
- PasswordExpiredException
-
A
PasswordExpiredException
indicates that a user password has expired. This exception is thrown by the connector when it can determine that a password has expired. For example, after successfully authenticating a user, the connector might determine that the user’s password has expired. The connector throws this exception to notify the application, which can then take the appropriate steps to notify the user.
- PermissionDeniedException
-
A
PermissionDeniedException
is thrown when the target resource will not allow a connector to perform a particular operation. An instance of thePermissionDeniedException
generally describes a native error (or wraps a native exception) that is returned by the target resource.
- PreconditionFailedException
-
A
PreconditionFailedException
is thrown to indicate that a resource’s current version does not match the version provided. This exception is equivalent to the HTTP status:412 Precondition Failed
.
- PreconditionRequiredException
-
A
PreconditionRequiredException
is thrown to indicate that a resource requires a version, but that no version was supplied in the request. This exception is equivalent to the HTTP status:428 Precondition Required
.
- RetryableException
-
A
RetryableException
indicates that the failure might be temporary, and that retrying the same request might succeed in the future.
- UnknownUidException
-
An
UnknownUidException
is thrown when a UID that is specified as input to a connector operation identifies no object on the target resource. When you implement theAuthenticateOp
, your connector can throw this exception if it is unable to locate the account necessary to perform authentication.
- NullPointerException (c# NullReferenceException)
-
Generic native exception
- UnsupportedOperationException (c# NotSupportedException)
-
Generic native exception
- IllegalStateException (c# InvalidOperationException)
-
Generic native exception
- IllegalArgumentException (c# ArgumentException)
-
Generic native exception

Java connectors
If none of the existing ICF connectors are suitable for your deployment, you can write your own connector. This chapter describes the steps to develop an OpenICF-compatible Java connector. Similar chapters exist to help you with writing scripted Groovy, and PowerShell connectors.
Types of connectors
In general, it takes longer to write a new Java connector than it does to use one of the scripted connector toolkits to write a scripted connector. Before you can write a Java connector, you must have a good understanding of the ICF SPI (refer to OpenICF SPI).
Scripted connectors do not require a complete understanding of the SPI, so connector development should be faster. The scripted connector implementations provided with IDM follow a general pattern and you can assess which implementation to use based on what the connector must be able to do.
For example, if you need to connect to a database, use the scriptedSQL implementation. To execute a remote command over SSH, use the scriptedSSH implementation. The details of these different scripted connector types are described in Selecting a Scripted Connector Implementation.
If the main purpose of your connector is to call a number of stored procedures or perform some SQL inserts, you can avoid learning the OpenICF SPI and focus on the required "actions" (create, delete, update, and so on). You can then implement these actions in a scripted connector. When you have stable scripts that do what they need to do, package them in a JAR, version them and your connector development is complete.
If you need to connect to new system with a client/server API in written in Java, you must write a new Java connector. This chapter helps you get started with that process.
Before you begin
Before you start developing your own connector, familiarize yourself with the structure of the SPI, by reading OpenICF SPI and the corresponding Javadoc for the ICF framework and its supported operations.
Connector archetype
ICF provides a Maven connector archetype that lets you get started with connector development.
The connector archetype assumes that you have Apache Maven installed on your system. Before you use the connector archetype, add the following to your Maven settings.xml
file, replacing backstage-username
and backstage-password
with your Backstage credentials:
<servers>
...
<server>
<username>backstage-username</username>
<password>backstage-password</password>
<id>archetype</id>
</server>
</servers>
...
<profiles>
<profile>
<id>test</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<repositories>
<repository>
<id>archetype</id>
<url>https://maven.forgerock.org/artifactory/private-releases</url>
</repository>
</repositories>
</profile>
</profiles>
To start building a connector by using the connector archetype, execute the following command, customizing these options to describe your new connector:
-
-DartifactId=sample-connector
-
-Dversion=0.0-SNAPSHOT
-
-Dpackage=org.forgerock.openicf.connectors.sample
-
-DconnectorName=Sample
This command imports the connector archetype and generates a new connector project:
mvn archetype:generate \ -DarchetypeGroupId=org.forgerock.openicf \ -DarchetypeArtifactId=connector-archetype \ -DarchetypeVersion=1.4.0 \ -DremoteRepositories=https://maven.forgerock.org/artifactory/private-releases \ -DarchetypeRepository=https://maven.forgerock.org/artifactory/private-releases \ -DgroupId=org.forgerock.openicf.connectors \ -DartifactId=sample-connector \ -Dversion=0.0-SNAPSHOT \ -Dpackage=org.forgerock.openicf.connectors.sample \ -DconnectorName=Sample [INFO] Scanning for projects...

At this point, you can enter Y (YES) to accept the default project, or N (NO) to customize the project for your connector.
You will notice in the preceding output that the default connector supports only the create
, delete
, search
, test
, and update
operations, and is not a poolable connector. To add support for additional operations, or to change any of the connector parameters, enter N (NO). The archetype then prompts you to set values for each additional parameter.
After you have imported the archetype once, you can use the local version of the archetype, as follows:
mvn archetype:generate -DarchetypeCatalog=local
Implement ICF operations
When you have generated the archetype, implement the ICF operations that your connector will support.
For information about implementing operations, and examples for a Java connector, refer to OpenICF SPI.
Scripted connectors with Groovy
The Groovy connector toolkit lets you run Groovy scripts to interact with any external resource.
The Groovy connector toolkit is not a complete connector in the traditional sense. Instead, it is a framework where you must write your own Groovy scripts to address your deployment requirements. The toolkit is bundled with IDM in the JAR openidm/connectors/groovy-connector-1.5.20.23.jar
.
IDM provides a number of deployment-specific scripts to help you get started with the Groovy connector toolkit. These scripts demonstrate how the toolkit can be used. The scripts cannot be used "as is" in your deployment but can be used as a starting point to base your customization.
The Groovy connector toolkit can be used with any ICF-enabled project (that is, any project where the OpenICF is installed).
About the Groovy scripting language
Groovy is a powerful, convenient scripting language for the Java platform. Groovy lets you take advantage of existing Java resources and generally makes development quicker. Syntactically, Groovy is similar to JavaScript. Extensive information about Groovy is available on the Groovy documentation site.
Selecting a scripted connector implementation
The Groovy connector toolkit provides five default connector implementations. The default implementations address the requirements of most target resources. If you use one of the default implementations, you only need to write the accompanying scripts and point your connector to their location. If the default implementations do not cover your target resource, you can use the Maven archetype to create a new connector project and write a custom Groovy-based connector from scratch.
The following list describes the default scripted connector implementations provided with the Groovy connector toolkit:
-
GROOVY
- a basic non-pooled Groovy connector, provided in theorg.forgerock.openicf.connectors.groovy.ScriptedConnector
class.POOLABLEGROOVY
- a poolable Groovy connector, provided in theorg.forgerock.openicf.connectors.groovy.ScriptedPoolableConnector
class.
When you have selected a scripted connector implementation, write the required scripts that correspond to that connector type. ICF operations with Groovy scripts provides information and examples on how to write scripts for the basic scripted connector implementation, and information on the extensions available for the other implementations.
ICF operations with Groovy scripts
The Groovy connector toolkit lets you run a Groovy script for any ICF operation, such as search, update, create, and so forth, on any external resource.
You must write a Groovy script that corresponds to each operation that your connector will support. For information about all the operations that are supported by the ICF framework, refer to OpenICF SPI.
Your scripted connector can implement the following ICF interfaces:
- Authenticate operation
-
Provides simple authentication with two parameters, presumed to be a user name and password.
- Create operation
-
Creates an object and its
uid
. - Delete operation
-
Deletes an object, referenced by its
uid
. - Resolve username operation
-
Resolves an object to its
uid
based on itsusername
. - Schema operation
-
Describes the object types, operations, and options that the connector supports.
- Script on connector operation
-
Enables IDM to run a script in the context of the connector. Any script that runs on the connector has the following characteristics:
-
The script runs in the same execution environment as the connector and has access to all the classes to which the connector has access.
-
The script has access to a connector variable that is equivalent to an initialized instance of the connector. At a minimum, the script can access the connector configuration.
-
The script has access to any script-arguments passed in by IDM.
-
- Script on resource operation
-
Runs a script directly on the target resource that is managed by the connector.
- Search operation
-
Searches the target resource for all objects that match the specified object class and filter.
- Sync operation
-
Polls the target resource for synchronization events; that is, native changes to objects on the target resource.
- Test operation
-
Tests the connector configuration. Testing a configuration checks that all elements of the environment that are referred to by the configuration are available. For example, the connector might make a physical connection to a host that is specified in the configuration to verify that it exists and that the credentials that are specified in the configuration are valid.
This operation might need to connect to the resource, and, as such, might take some time. Do not invoke this operation too often, such as before every provisioning operation. The test operation is not intended to check that the connector is alive (that is, that its physical connection to the resource has not timed out).
You can invoke the test operation before a connector configuration has been validated.
- Update operation
-
Updates (modifies or replaces) objects on a target resource.
The following sections provide more information and pointers to sample scripts for all the operations implemented in the Groovy connector toolkit.
Variables available to all Groovy scripts
The following variables are available to all scripts used by the Groovy Connector. Additional variables are available to specific scripts, as described in the sections that follow:
configuration
-
A handle to the connector’s configuration object is injected into all scripts.
operation
-
The connector injects the name of the action or operation into the script, to indicate which action is being called.
The sample scripts for the Groovy connector define one script file per action. You can use a single file, or amalgamate multiple actions into one file. For example, the CREATE and UPDATE operations often share the same code.
The operation type can be one of the following:
-
ADD_ATTRIBUTE_VALUES
-
AUTHENTICATE
-
CREATE
-
DELETE
-
GET_LATEST_SYNC_TOKEN
-
REMOVE_ATTRIBUTE_VALUES
-
RESOLVE_USERNAME
-
RUNSCRIPTONCONNECTOR
-
RUNSCRIPTONRESOURCE
-
SCHEMA
-
SEARCH
-
SYNC
-
TEST
-
UPDATE
-
options
-
The ICF framework passes an
OperationOptions
object to most of the operations. The Groovy connector injects this object, as is, into the scripts. For example, the search, query, and sync operations pass the attributes to get as an operation option.The most common options are as follows:
-
AttributesToGet
(String[]) for search and sync operations -
RunAsUser
(String) for any operation -
RunWithPassword
(GuardedString) for any operation -
PagedResultsCookie
(String) for search operations -
PagedResultsOffset
(Int) for search operations -
PageSize
(Int) for search operations -
SortKeys
(Sortkey[]) for search operations
-
- objectClass
-
The category or type of object that is managed by the connector, such as ACCOUNT and GROUP.
- log
-
A handle to the default ICF logging facility.
- connection
-
Available to the ScriptedREST, ScriptedCREST, and ScriptedSQL implementations, this variable initiates the HTTP or SQL connection to the resource.
Authenticate script
An authenticate script is required if you want to use pass-through authentication to the backend resource. If your connector does not need to authenticate to the resource, the authenticate script should allow the authId
to pass through by default.
A sample authenticate script for an SQL database is provided in openidm/samples/scripted-sql-with-mysql/tools/AuthenticateScript.groovy
.
The following connectors support pass-through authentication using the AuthenticateOp
interface by default:
All Scripted Groovy-based connectors are capable of pass-through authentication if the AuthenticateScript.groovy script is implemented, but the only default implementation is the ScriptedSQL connector.

def password = createAttributes.getPassword() as GuardedString;
assert password != null, 'Password must be provided on create'
//...
def uid = createTheUser(createAttributes);
return uid
Search or query script
A search script searches for one or more objects on the external resource. Connectors that do not support searches should throw an UnsupportedOperationException
.

Provides a convenient way to access the query filter parameter. For example:
query = [ operation: "CONTAINS", left: attribute, right: "value", not: true/false ] query = [ operation: "ENDSWITH", left: attribute, right: "value", not: true/false ] query = [ operation: "STARTSWITH", left: attribute, right: "value", not: true/false ] query = [ operation: "EQUALS", left: attribute, right: "value", not: true/false ] query = [ operation: "GREATERTHAN", left: attribute, right: "value", not: true/false ] query = [ operation: "GREATERTHANOREQUAL", left: attribute, right: "value", not: true/false ] query = [ operation: "LESSTHAN", left: attribute, right: "value", not: true/false ] query = [ operation: "LESSTHANOREQUAL", left: attribute, right: "value", not: true/false ] query = null : then we assume we fetch everything // AND and OR filter - embed these left/right queries: query = [ operation: "AND", left: query1, right: query2 ] query = [ operation: "OR", left: query1, right: query2 ]
For example, the equality query filter
"sn == Smith"
would be represented by the following query Map:[ operation: "EQUALS", left: "sn", right: "Smith", not: false ]
- handler
-
A Closure handler for processing the search results.
- log
-
A logger instance for the connector.
- Returns
-
Optionally, the script can return a search result. The result can be be returned as a
SearchResult
object or as aString
that represents thepagedResultsCookie
to be used for the next paged results.
Returning search results
In a search operation, a result handler (callback) is passed to the script to return the results one by one. The handler must be called for every query result. The handler variable that is passed to the script is a Groovy Closure
. You can call the handler in the following ways:
-
Using an ICF
ConnectorObject
object.You can use the
ConnectorObjectBuilder
to build this object. For example:def builder = new ConnectorObjectBuilder() builder.setUid(uidValue) builder.setName(nameValue) builder.setObjectClass(ObjectClass.ACCOUNT) builder.addAttribute("sn", snValue) // Call the handler with the ConnectorObject object handler builder.build()
-
Using a Groovy Closure.
In this case the Closure delegates calls to a specific Object that implements these calls. For example:
handler { // The handler parameter here is a Closure uid uidValue // (mandatory), the method resolution for 'uid' is delegated to the Object // handling the Closure. This is the ICF __UID__ id nameValue // (mandatory), the method resolution for 'id' is delegated to the Object // handling the Closure. This is the ICF __NAME__ attribute "sn", snValue // (optional), the method resolution for 'id' is delegated to the // Object handling the Closure // attribute <attribute2Name>, <attribute2Value> // etc... }
In the following example, the handler is called within a loop to return all the results of a query:
for (user in userList) { handler { uid user.userName id user.userName user.attributes.each(){ key,value -> attribute key, value } } }
Update script
An update script updates an object in the external resource. Connectors that do not support update operations should throw an UnsupportedOperationException
.
A sample update script for an SQL database is provided in openidm/samples/scripted-sql-with-mysql/tools/UpdateScript.groovy
.
- Input variables
-
The following variables are available to an update script:
- configuration
-
A handler to the connector’s configuration object.
- options
-
A handler to the Operation Options.
- operation
-
An OperationType that corresponds to the action (
UPDATE
). - objectClass
-
The object class that is updated, such as
__ACCOUNT__
or__GROUP__
. - attributes
-
A collection of
ConnectorAttributes
that represent the entry attributes to update. - uid
-
The UID of the object to be updated. The UID corresponds to the OpenICF
UID
attribute. - id
-
The name of the object to be updated (optional). The id corresponds to the ICF
__NAME__
attribute. It will not be injected and set unless the update is a rename. - log
-
A logger instance for the connector.
- Returns
-
The user unique ID (ICF
__UID__
) of the updated object. Thetype
of the returned UID must be astring
or aUid
. If the UID is not modified by the update operation, return the value of the uid injected into the script.
def operation = operation as OperationType
def updateAttributes = attributes as Set<Attribute>
def configuration = configuration as ScriptedConfiguration
def id = id as String
def log = log as Log
def objectClass = objectClass as ObjectClass
def options = options as OperationOptions
def uid = uid as Uid
log.ok("Update...")
switch (operation) {
case OperationType.UPDATE:
switch (objectClass) {
case ObjectClass.ACCOUNT:
// ...
for (Attribute a : updateAttributes) {
if (a.is(Name.NAME)) {
// ...
return uid
Delete script
A delete script deletes an object in the external resource. Connectors that do not support delete operations should throw an UnsupportedOperationException
.
A sample delete script for an SQL database is provided in openidm/samples/scripted-sql-with-mysql/tools/DeleteScript.groovy
.
- Input variables
-
The following variables are available to an update script:
- configuration
-
A handler to the connector’s configuration object.
- options
-
A handler to the Operation Options.
- operation
-
An OperationType that corresponds to the action (
DELETE
). - objectClass
-
The object class that is deleted, such as
__ACCOUNT__
or__GROUP__
. - uid
-
The UID of the object to be deleted. The UID corresponds to the OpenICF
__UID__
attribute. - log
-
A logger instance for the connector.
- Returns
-
This script has no return value but should throw an exception if the delete is unsuccessful.
Synchronization script
A synchronization script synchronizes objects between two resources. The script should retrieve all objects in the external resource that have been updated since some defined token.
A sample synchronization script for an SQL database is provided in openidm/samples/scripted-sql-with-mysql/tools/SyncScript.groovy
.
- Input variables
-
The following variables are available to a sync script:
- configuration
-
A handler to the connector’s configuration object.
- options
-
A handler to the Operation Options.
- operation
-
An OperationType that corresponds to the action (
GET_LATEST_SYNC_TOKEN
orSYNC
). - objectClass
-
The object class that is synchronized, such as
__ACCOUNT__
or__GROUP__
. - token
-
The value of the sync token.
- handler
-
A
Closure
handler for processing the sync results. - log
-
A logger instance for the connector.
- Returns
-
If the operation type is
GET_LATEST_SYNC_TOKEN
, the script must return an object that represents the last knownSyncToken
for the correspondingObjectClass
. For example:
def operation = operation as OperationType
def configuration = configuration as ScriptedConfiguration
def log = log as Log
def objectClass = objectClass as ObjectClass
def options = options as OperationOptions
def token = token as Object
case OperationType.GET_LATEST_SYNC_TOKEN:
switch (objectClass) {
case ObjectClass.ACCOUNT:
return new SyncToken(17);
case ObjectClass.GROUP:
return new SyncToken(16);
case ObjectClass.ALL:
return new SyncToken(17);
// ....
If the operation type is SYNC
, the script must return a new SyncToken
for the corresponding ObjectClass
. A Sync result handler (callback) is passed to the script to return the Sync results one by one. The handler must be called for each result.
The handler variable that is passed to the script is a Groovy Closure. It can be called in the following ways:
-
With an ICF
SyncDelta
object.You can use a
SyncDeltaBuilder
to build this object. For example:def builder = new SyncDeltaBuilder() builder.setUid(uidValue) builder.setToken(new SyncToken(5)) builder.setDeltaType(SyncDeltaType.CREATE) builder.setObject(connectorObject) // Use the ConnectorObjectBuilder class to build the ConnectorObject object. // Call the handler with the SyncDelta object handler builder.build()
-
Using a Groovy Closure.
In this case, the Closure delegates calls to a specific Object that implements these calls. For example:
handler { // The handler parameter here is a Closure syncToken tokenValue // (mandatory), the method resolution for 'syncToken' is delegated to the Object handling the Closure <DELTA_TYPE>() // (mandatory), DELTA_TYPE should be one of: CREATE, UPDATE, DELETE, CREATE_OR_UPDATE object connectorObject // (optional if DELTA_TYPE is a DELETE), the method resolution for 'object' is delegated to the Object handling the Closure previousUid prevUidValue // (optional), use only if UID has changed }
In the following example, the handler is called twice - first for a CREATE and then for a DELETE:
// CREATE handler({ syncToken 15 CREATE() object { id nameValue uid uidValue as String objectClass ObjectClass.GROUP attribute 'gid', gidValue attribute 'description', descriptionValue } }) // DELETE handler({ syncToken 16 DELETE(uidValue) }
Optionally, when the action is SYNC, you might want to return a
SyncToken
at the end of the script. This is a convenient way to update the sync token if no relevant sync events are found.
Schema script
A schema script builds the schema for the connector, either from a static, predefined schema, or by reading the schema from the external resource. The script should use the builder
object to create the schema.
A sample schema script for an SQL database is provided in openidm/samples/scripted-sql-with-mysql/tools/SchemaScript.groovy
.
- Input variables
-
The following variables are available to a sync script:
- configuration
-
A handler to the connector’s configuration object.
- operation
-
An OperationType that corresponds to the action (
SCHEMA
). - builder
-
An instance of the
ICFObjectBuilder
. Theschema()
method should be called with a Closure parameter defining the schema objects.For more information, refer to Using the
builder
Parameter. - log
-
A logger instance for the connector.
- Returns
-
This script has no return value.
Using the builder
parameter
The builder.schema()
must call the delegates objectClass
method and operationOption
method to define the schema.
Call the objectClass()
method for each object type (account, group, and so on) that must be defined. Include the call to the following delegates:
-
type()
- the name for this object type -
attribute()
- define a single attribute for this object type -
attributes()
- define multiple attribute for this object type -
disable()
- list the operations for which this object type is forbidden
The following example defines a simple ACCOUNT object type:
builder.schema({
objectClass {
type ObjectClass.ACCOUNT_NAME
attribute OperationalAttributeInfos.PASSWORD
attribute PredefinedAttributeInfos.DESCRIPTION
attribute 'groups', String.class, EnumSet.of(MULTIVALUED)
attributes {
userName String.class, REQUIRED
email REQUIRED, MULTIVALUED
__ENABLE__ Boolean.class
createDate NOT_CREATABLE, NOT_UPDATEABLE
lastModified Long.class, NOT_CREATABLE, NOT_UPDATEABLE, NOT_RETURNED_BY_DEFAULT
passwordHistory String.class, MULTIVALUED, NOT_UPDATEABLE, NOT_READABLE, NOT_RETURNED_BY_DEFAULT
firstName()
sn()
}
}
}
Resolve username script

.
- Input variables
-
The following variables are available to a resolve username script:
- configuration
-
A handler to the connector’s configuration object.

A string that represents the username of the object.
- log
-
A logger instance for the connector.
- Returns
-
The user unique ID (ICF
__UID__
) of the object. Thetype
of the returned UID must be astring
or aUid
. If a null value or an object type other thanstring
orUid
is returned, the script must throw an exception.
def operation = operation as OperationType
def configuration = configuration as ScriptedConfiguration
def username = username as String
def log = log as Log
def objectClass = objectClass as ObjectClass
def options = options as OperationOptions
if (objectClass.is(ObjectClass.ACCOUNT_NAME)) {
if (username.equals("TESTOK1")) {
return new Uid("123")
}
throw new UnknownUidException();
}

Custom configuration initialization
Connectors created with the Groovy connector toolkit are stateful connectors by default. This means the connector configuration instance is created only once.
The Groovy connector toolkit is precompiled code and connector configurations are initialized in a specific way. If you have specific initialization requirements, you can customize how the connector configuration instance is initialized before the first script is evaluated. The CustomizerScript.groovy
file lets you define custom closures to interact with the default implementation.
The CustomizerScript.groovy
file, provided with each compiled connector implementation, defines closures, such as init {}
, decorate {}
, and release {}
. These closures are called during the lifecycle of the configuration.
When you unpack the Groovy connector toolkit JAR file, the CustomizerScript.groovy
file is located at org/forgerock/openicf/connectors/connector-implementation
.
Scripted connectors with PowerShell
You can use the PowerShell connector toolkit to create connectors that can provision any Microsoft system, including, but not limited to, Active Directory, Microsoft SQL, MS Exchange, Sharepoint, Office365, and Azure. Any task you can perform with PowerShell can be executed through connectors based on this toolkit.
The PowerShell connector toolkit is not a complete connector, in the traditional sense. Instead, it is a framework where you must write your own PowerShell scripts to address your Microsoft Windows ecosystem requirements.
Connectors created with the PowerShell connector toolkit run on the .NET platform and require the installation of a .NET connector server on the Windows system. To install the .NET connector server, follow the instructions in Install .NET RCS. These connectors also require PowerShell V2.
The PowerShell connector toolkit is available from the BackStage download site. To install the connector, download the archive (mspowershell-connector-1.4.7.0.zip
) and extract the MsPowerShell.Connector.dll
to the same folder where the Connector Server (connectorserver.exe
) is located. IDM provides sample connector configurations and scripts that enable you to get started with this toolkit.
About PowerShell
PowerShell combines a command-line shell and scripting language, built on the .NET Framework. For more information, refer to PowerShell Documentation. |
Connector troubleshooting
Logs
It can be difficult to determine if the root cause of a problem is at the ICF or connector level, or at the application level.
The ICF API sets the LoggingProxy
at a very high level. You can consider the Logging Proxy as the border between the application (IDM) and the ICF framework.
For more information about logging, refer to Connector logs.
