Package com.iplanet.sso

Class SSOTokenManager

java.lang.Object

com.iplanet.sso.SSOTokenManager

@Supported
public class SSOTokenManager
extends Object

SSOTokenManager is the final class that is the mediator between the SSO APIs and SSO providers. When an SSO client makes an API invocation, SSOTokenManager will delegate that call to the SSO provider/plug-in. The SSO provider will execute the call and return the results to SSOTokenManager, which in turn returns the results to the SSO client. This decouples the SSO clients from the actual SSO providers. You should be able to replace the SSO provider without having to modify the SSO client. However, the clients can invoke the class methods on the objects returned by the SSOTokenManager.

SSOTokenManager is a singleton class; there can be, at most, only one instance of SSOTokenManager in any given JVM.

SSOTokenManager currently supports only two kinds of provider: Grappa and OpenAM.

It is assumed that the provider classes or the JAR file is in the CLASSPATH so that they can be found automatically. Providers can be configured using providerimplclass property. This property must be set to the complete (absolute) package name of the main class of the provider. For example, if the provider class is com.iplanet.sso.providers.dpro.SSOProviderImpl, that entire class name including package prefixes MUST be specified. The main class MUST implement the com.iplanet.sso.SSOProvider interface and MUST have a public no-arg default constructor.

The class SSOTokenManager is a final class that provides interfaces to create and validate SSOTokens.

It is a singleton class; an instance of this class can be obtained by calling SSOTokenManager.getInstance().

Having obtained an instance of SSOTokenManager, its methods can be called to create SSOToken, get SSOToken given the SSOTokenID in string format, and to validate SSOTokens.

Method Detail

getInstance

@Supported
public static SSOTokenManager getInstance()
                                   throws SSOException

Returns the singleton instance of SSOTokenManager.

Returns:

The singleton SSOTokenManager instance

Throws:

SSOException - if unable to get the singleton SSOTokenManager instance.

createSSOToken

@Supported
public SSOToken createSSOToken(javax.servlet.http.HttpServletRequest request)
                        throws UnsupportedOperationException,
                               SSOException

Creates a single sign on token from HttpServletRequest

Parameters:

request - The HttpServletRequest object which contains the session string.

Returns:

single sign on SSOToken

Throws:

SSOException - if the single sign on token cannot be created.

UnsupportedOperationException - if this is an unsupported operation.

createSSOToken

@Supported
public SSOToken createSSOToken(String tokenId)
                        throws UnsupportedOperationException,
                               SSOException

Creates a single sign on token from the single sign on token ID. Note:-If you want to do Client's IP address validation for the single sign on token then use creatSSOToken(String, String) OR createSSOToken(HttpServletRequest).

Parameters:

tokenId - Token ID of the single sign on token

Returns:

single sign on token

Throws:

SSOException - if the single sign on token cannot be created.

UnsupportedOperationException - If the operation is not supported by the provider.

createSSOToken

@Supported
public SSOToken createSSOToken(String tokenId,
                               String clientIP)
                        throws UnsupportedOperationException,
                               SSOException

Creates a single sign on token from the single sign on token ID.

Parameters:

tokenId - Token ID of the single sign on token

clientIP - Client IP address. This must be the IP address of the client/user who is accessing the application.

Returns:

single sign on token

Throws:

SSOException - if the single sign on token cannot be created.

UnsupportedOperationException - If the operation is not supported by the provider.

isValidToken

@Supported
public boolean isValidToken(SSOToken token)

Returns true if a single sign on token is valid. Your token may have its idle time reset. You have been warned.

Parameters:

token - The single sign on token object to be validated.

Returns:

true if the single sign on token is valid.

isValidToken

@Supported
public boolean isValidToken(SSOToken token,
                            boolean resetIdleTime)

Returns true if a single sign on token is valid, resetting the token's idle time if and only if the flag allows us to.

Parameters:

token - The single sign on token object to be validated.

Returns:

true if the single sign on token is valid.

validateToken

@Supported
public void validateToken(SSOToken token)
                   throws SSOException

Returns true if the single sign on token is valid.

Parameters:

token - The single sign on token object to be validated.

destroyToken

@Supported
public void destroyToken(SSOToken token)
                  throws SSOException

Destroys a single sign on token.

refreshSession

@Supported
public void refreshSession(SSOToken token)
                    throws SSOException

Refresh the Session corresponding to the single sign on token from the Session Server. This method should only be used when the client cannot wait the "session cache interval" for updates on any changes made to the session properties in the session server. If the client is remote, calling this method results in an over the wire request to the session server.

Parameters:

token - single sign on token

Throws:

SSOException - if the session reached its maximum session time, or the session was destroyed, or there was an error while refreshing the session.

destroyToken

@Supported
public void destroyToken(SSOToken destroyer,
                         SSOToken destroyed)
                  throws SSOException

Destroys a single sign on token.

Parameters:

destroyer - The single sign on token object used to authorize the operation

destroyed - The single sign on token object to be destroyed.

@Supported
public Set getValidSessions(SSOToken requester,

                     throws SSOException

Returns a list of single sign on token objects which correspond to valid Sessions accessible to requester. Single sign on tokens returned are restricted: they can only be used to retrieve properties and destroy sessions they represent.

Parameters:

requester - The single sign on token object used to authorize the operation
