This makes it easy to demonstrate and learn features before you fully understand access control. When deploying DS servers in production, grant only the necessary access. ## Access control mechanisms DS servers support two access control mechanisms, ACIs *(tooltip: \
\

An instruction or rule that can be used to grant or deny access to users to perform operations on a server.\

\
)* for directory servers, and global access control policies for proxy servers. | Characteristic | Access Control Instructions (ACIs) | Global Access Control Policies | | ---------------- | -------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------- | | Default for | Directory Servers. | Directory Proxy Servers. | | Where | Operational `aci` attributes (replicated).`global-aci` properties (not replicated). | `global-access-control-policy` entries (not replicated). | | Default access | No access unless explicitly granted.(1) | No access unless explicitly granted. | | Level of control | Very fine-grained control that can depend on the directory data. | Overall control that does not require access to directory data. | | Interaction(2) | When configured, global policies have no effect. | When configured, ACIs have no effect. | | Reference | [Directory server ACIs](#acis).[DSEE Compatible Access Control Handler](../configref/objects-dsee-compat-access-control-handler.html). | [Global Access Control Policy](../configref/objects-global-access-control-policy.html). | (1) The `bypass-acl` privilege grants users access regardless of ACIs. (2) In the rare event that you choose to change the type of server and the type of its access control handler, you must stop the server and make the change with the `dsconfig --offline` command. Some operations require administrative privileges *and* access control. By combining access control and privileges, you effectively restrict the scope of the privileges. Privileges are described in [Administrative roles](admin.html). ## Directory server ACIs | | | | - | ---------------------------------------------------------------------------------------------------------- | | | ACIs are for directory servers. For proxy servers, use [global policies](#global-access-control-policies). | * ACIs set scoped permissions which depend on what operation is requested, who requested the operation, and how the client connected to the server. * To let other users change ACIs, grant them the `modify-acl` privilege and permission to edit `aci` attributes. For examples, refer to [Learn access control](../getting-started/acis.html). ### ACI syntax ``` targets (version 3.0; acl "name"; permissions subjects;) ``` * targets The ACI applies to the target entries, attributes, controls, and extended operations. To define multiple *targets*, put each target in parentheses, `()`. All targets must match for the ACI to apply (`AND`). * name Human-readable description of what the ACI does. * permissions Actions to allow, and which to deny. Paired with subjects. * subjects Clients the permissions apply to, and the conditions under which they apply. Paired with permissions. Separate multiple permissions-subjects pairs with semicolons, `;`. At least one must match for the ACI to apply (`OR`). ### ACI targets Most target expressions let you use either `=` (target must match), or `!=` (target must not match): * `(target [!]= "ldap:///DN")` The ACI scope is the entry with distinguished name DN, and subordinates. Use an asterisk, `*`, to replace attribute types, attribute values, and entire DN components. The following example targets `uid=bjensen,ou=People,dc=example,dc=com` and `cn=My App,ou=Apps,dc=example,dc=com`: ```aci (target = "ldap:///*=*,*,dc=example,dc=com") ``` The DN must be in the subtree of the entry where the ACI is defined. If you omit `target`, the ACI applies to its entry. If you omit `targetscope` as well, the ACI applies to its entry and all subordinates. * `(targetattr [!]= "attr-list")` The ACI targets the specified attributes. In the attr-list, separate attribute names with `||`. This ACI affects its entry, or the entries specified by other targets in the ACI. For best performance, explicitly list attributes. Use an asterisk, `*`, to specify all user attributes. Use a plus sign, `+`, to specify all operational attributes. A negated attr-list of operational attributes matches only other operational attributes, never any user attributes, and vice-versa. If you omit `targetattr`, by default this ACI does not affect attributes. * `(targetfilter [!]= "ldap-filter")` This ACI is scoped to match the ldap-filter dynamically, as in an LDAP search. The ldap-filter can be any valid LDAP filter. * `(targattrfilters = "expression")` Use this target specification when managing changes made to particular attributes. The expression takes one of the following forms. Separate expressions with commas (`,`): ``` op=attr1:filter1[&& attr2:filter2 ...][,op=attr3:filter3[&& attr4:filter4 ...] ...] ``` The op can be either `add` for operations creating attributes, or `del` for operations removing them. Replace attr with an attribute type. Replace filter with an LDAP filter that corresponds to the attr attribute type. * `(targetscope = "base|onelevel|subtree|subordinate")` * `base` refers to the entry with the ACI. * `onelevel` refers to immediate children. * `subtree` refers to the base entry and all children. * `subordinate` refers to all children only. If you omit `targetscope`, the default is `subtree`. * `(targetcontrol [!]= "alias-or-OID")` The ACI targets the LDAP control with the specified alias or object identifier alias-or-OID. Separate multiple aliases or OIDs with `||`. DS servers support the following control aliases for ACIs: * `AccountUsable`, `AccountUsability` (`1.3.6.1.4.1.42.2.27.9.5.8`) * `ActiveDirectoryChangeNotification`, `AdChangeNotification` (`1.2.840.113556.1.4.528`) * `Affinity` (`1.3.6.1.4.1.36733.2.1.5.2`) * `Assertion`, `LdapAssertion` (`1.3.6.1.1.12`) * `AuthorizationIdentity`, `AuthzId` (`2.16.840.1.113730.3.4.16`) * `Csn`, `ChangeNumber`, `ChangeSequenceNumber` (`1.3.6.1.4.1.42.2.27.9.5.9`) * `Ecl`, `EclCookie`, `ExternalChangelogCookie` (`1.3.6.1.4.1.26027.1.5.4`) * `EffectiveRights`, `GetEffectiveRights` (`1.3.6.1.4.1.42.2.27.9.5.2`) * `ManageDsaIt` (`2.16.840.1.113730.3.4.2`) * `MatchedValues` (`1.2.826.0.1.3344810.2.3`) * `NoOp` (`1.3.6.1.4.1.4203.1.10.2`) * `PasswordPolicy`, `PwdPolicy`, `PwpPolicy` (`1.3.6.1.4.1.42.2.27.8.5.1`) * `PasswordQualityAdvice` (`1.3.6.1.4.1.36733.2.1.5.5`) * `PermissiveModify` (`1.2.840.113556.1.4.1413`) * `PersistentSearch`, `PSearch` (`2.16.840.1.113730.3.4.3`) * `PostRead` (`1.3.6.1.1.13.2`) * `PreRead` (`1.3.6.1.1.13.1`) * `ProxiedAuthV1` (`2.16.840.1.113730.3.4.12`) * `ProxiedAuthV2`, `ProxiedAuth` (`2.16.840.1.113730.3.4.18`) * `RealAttrsOnly`, `RealAttributesOnly` (`2.16.840.1.113730.3.4.17`) * `RelaxRules` (`1.3.6.1.4.1.4203.666.5.12`) * `ReplicationRepair` (`1.3.6.1.4.1.26027.1.5.2`) * `ServerSideSort`, `Sort` (`1.2.840.113556.1.4.473`) * `SimplePagedResults`, `PagedResults` (`1.2.840.113556.1.4.319`) * `SubEntries` (`1.3.6.1.4.1.4203.1.10.1`) * `SubtreeDelete`, `TreeDelete` (`1.2.840.113556.1.4.805`) * `TransactionId`, `TxnId` (`1.3.6.1.4.1.36733.2.1.5.1`) * `VirtualAttrsOnly`, `VirtualAttributesOnly` (`2.16.840.1.113730.3.4.19`) * `Vlv`, `VirtualListView` (`2.16.840.1.113730.3.4.9`) To use an LDAP control, the bind DN user must have `allow(read)` permissions. This target cannot be restricted to a specific subtree. * `(extop [!]= "alias-or-OID")` This ACI targets the LDAP extended operation with the specified alias or object identifier alias-or-OID. Separate multiple aliases or OIDs with `||`. DS servers support the following extended operation aliases for ACIs: * `Cancel` (`1.3.6.1.1.8`) * `GetConnectionId`, `ConnectionId` (`1.3.6.1.4.1.26027.1.6.2`) * `GetSymmetricKey`, `SymmetricKey` (`1.3.6.1.4.1.26027.1.6.3`) * `PasswordModify` (`1.3.6.1.4.1.4203.1.11.1`) * `PasswordPolicyState` (`1.3.6.1.4.1.26027.1.6.1`) * `StartTls` (`1.3.6.1.4.1.1466.20037`) * `WhoAmI` (`1.3.6.1.4.1.4203.1.11.3`) To use an LDAP extended operation, the bind DN user must have `allow(read)` permissions. This target cannot be restricted to a specific subtree. ### ACI permissions ACI permission definitions take one of the following forms: ``` allow(action[, action ...]) deny(action[, action ...]) ``` | | | | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | Avoid using `deny`.Instead, explicitly `allow` access only as needed. What looks harmless and simple in tests and examples can grow complicated quickly with nested ACIs. | The action is one of the following: * `add` Entry creation, as for an LDAP add operation. * `all` All permissions, except `export`, `import`, `proxy`. * `compare` Attribute value comparison, as for an LDAP compare operation. * `delete` Entry deletion, as for an LDAP delete operation. * `export` Entry export during a modify DN operation. Despite the name, this action is unrelated to LDIF export operations. * `import` Entry import during a modify DN operation. Despite the name, this action is unrelated to LDIF import operations. * `proxy` Access the ACI target using the rights of another user. * `read` Read entries and attributes, or use an LDAP control or extended operation. * `search` Search the ACI targets. Combine with `read` to read the search results. * `selfwrite` Add or delete own DN from a group. * `write` Modify attributes on ACI target entries. ### ACI subjects Subjects restrict whether the ACI applies depending on who connected, and when, where, and how they connected. Most target expressions allow you to use either `=` (condition must match), or `!=` (condition must not match): * `authmethod [!]= "none|simple|ssl|sasl mech"` * `none`: ignore the authentication method. * `simple`: simple authentication. * `ssl`: certificate-based authentication over LDAPS. * `sasl mech`: SASL authentication, where *mech* is the SASL mechanism, such as `EXTERNAL`, or `GSSAPI`. * `dayofweek [!]= "day[, day…​]"` Valid days: * `sun` (Sunday) * `mon` (Monday) * `tue` (Tuesday) * `wed` (Wednesday) * `thu` (Thursday) * `fri` (Friday) * `sat` (Saturday) * `dns [!]= "hostname"` Use an asterisk, `*`, to replace name components, as in `dns = "*.example.com"`. * `groupdn [!]= "ldap:///DN [|| ldap:///DN …​]"` The subjects are the members of the group with the specified DN. * `ip [!]= "addresses"` Valid IP addresses: * Individual IPv4 or IPv6 addresses. Put IPv6 addresses in brackets, as in `ldap://[address]/subnet-prefix`, where `/subnet-prefix` is optional. * Addresses with asterisk (`*`) for a subnet or host number. * CIDR notation. * Forms such as `192.168.0.*+255.255.255.0` to specify subnet masks. * `ssf = "strength"` The security strength factor (`ssf`) reflects the cipher key strength for a secure connection. The `ssf` takes an integer in the range 0-1024: * `ssf = 0`: send plain text with no connection security. * `ssf = 1`: configure TLS without a cipher. The server verifies integrity using packet checksums, but all content is sent in cleartext. * `ssf >= "256"`: require a cipher strength of at least 256 bits. The `ssf` setting can help to neutralize STRIPTLS attacks. A TLS stripping attack is a man-in-the-middle attack. It takes advantage of the fact that the initial TLS handshake starts on an unencrypted connection. An attacker who has control of the network makes it appear during the handshake that TLS is not available. Client applications may then fall back to using the connection without TLS encryption. In this case, ACIs with `ssf` settings greater than `1` require encryption to grant access. Use an appropriately high `ssf` setting in your ACIs, such as `ssf >= "256"` to ensure secure encryption. * `timeofday = "hhmm"` Express times, *hhmm*, as on a 24-hour clock. For example, 1:15 PM is written `1315`. * `userattr [!]= "attr#value"` The `userattr` subject specifies an attribute that must match on the bind entry and the ACI target entry: * Use `userattr [!]= "attr#value"` when the bind entry and target entry have the same attribute. The attr is a user attribute. The value is the attribute value. The server does an internal search to get the attributes of the bind entry. Therefore, this ACI subject does not work with operational attributes. * Use `userattr [!]= ldap-url#LDAPURL"` when the target entry is identified by the LDAP Uniform Resource Locator (LDAP URL) *(tooltip: \
\

A standard uniform resource locator for accessing entries in a directory.\

\
)*, and the bind entry is in the subtree scope of the DN in the LDAP URL. * Use `userattr [!]= "[parent[child-level].]attr#GROUPDN"` when the bind DN is a member of the group identified by the attr of the target entry. * Use `userattr [!]= "[parent[child-level].]attr#USERDN"` when the bind DN is referenced by the attr of the target entry. The optional inheritance specification, `parent[child-level].`, defines how many levels below the target entry inherit the ACI. The child-level is a number from 0 to 9, with 0 indicating the target entry only. Separate multiple child-level digits with commas (`,`). * `userdn [!]= "ldap-url+_[|| _ldap-url+ …​]"` This subject matches either a valid LDAP URL, or a special LDAP URL-like keyword from the following list: * `ldap:///all` Match authenticated users. * `ldap:///anyone` Match anonymous and authenticated users. * `ldap:///parent` Match when the bind DN is a parent of the ACI target. * `ldap:///self` Match when the bind DN entry corresponds to ACI target. ### ACI evaluation The rules the server follows are simple: 1. To determine whether an operation is allowed or denied, DS servers look in the directory for the target of the operation. The server collects any ACI values from that entry, and then walks up the directory tree to the base DN, collecting all ACI values en route. It then collects global ACI values. 2. The server separates the ACI values into two lists. One list contains all the ACI values that match the target and deny the required access. The other list contains all the ACI values that match the target and allow the required access. 3. If the deny list contains any ACI values after this procedure, access is immediately denied. 4. If the deny list is empty, the server processes the allow list. If the allow list contains any ACI values, access is allowed. 5. If both lists are empty, access is denied. | | | | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | Some operations require multiple permissions and involve multiple targets. Evaluation therefore takes place multiple times.For example, a search operation requires the `search` permission for each attribute in the search filter. If applicable ACIs allow all search permissions, the server uses `read` permissions to decide which attributes and values to return. | ### ACI by operation * Add The ACI must allow the `add` permission to entries in the target. This implicitly lets users set attributes and values. Use `targattrfilters` to explicitly deny access to any values if required. For example, this ACI lets `uid=bjensen,ou=People,dc=example,dc=com` add an entry: ```ldif aci: (version 3.0;acl "Add entry"; allow (add) (userdn = "ldap:///uid=bjensen,ou=People,dc=example,dc=com");) ``` * Bind Because a bind establishes the user's identity and derived authorizations, ACI is irrelevant for this operation and is not checked. To prevent authentication, disable the account instead. * Compare The ACI must allow the `compare` permission to the attribute in the target entry. For example, this ACI lets `uid=bjensen,ou=People,dc=example,dc=com` compare values against the `sn` attribute: ```ldif aci: (targetattr = "sn")(version 3.0;acl "Compare surname"; allow (compare) (userdn = "ldap:///uid=bjensen,ou=People,dc=example,dc=com");) ``` * Delete The ACI must allow the `delete` permission to the target entry. This implicitly lets users delete attributes and values in the target. Use `targattrfilters` to explicitly deny access to the values if required. For example, this ACI lets `uid=bjensen,ou=People,dc=example,dc=com` delete an entry: ```ldif aci: (version 3.0;acl "Delete entry"; allow (delete) (userdn = "ldap:///uid=bjensen,ou=People,dc=example,dc=com");) ``` * Modify The ACI must allow the `write` permission to attributes in the target entries. This implicitly lets users modify all values of the target attribute. Use `targattrfilters` to explicitly deny access to specific values if required. For example, this ACI lets `uid=bjensen,ou=People,dc=example,dc=com` modify the `description` attribute in an entry: ```ldif aci: (targetattr = "description")(version 3.0; acl "Modify description"; allow (write) (userdn = "ldap:///uid=bjensen,ou=People,dc=example,dc=com");) ``` * ModifyDN If the entry is being moved to a `newSuperior`, the `export` permission must be allowed on the target, and the `import` permission must be allowed on the `newSuperior` entry. The ACI must allow `write` permission to the attributes in the old RDN and the new RDN. This implicitly lets users write all values of the old RDN and new RDN. Use `targattrfilters` to explicitly deny access to values used if required. For example, this ACI lets `uid=bjensen,ou=People,dc=example,dc=com` rename entries named with the `uid` attribute to new locations: ```ldif aci: (targetattr = "uid")(version 3.0;acl "Rename uid= entries"; allow (write, import, export) (userdn = "ldap:///uid=bjensen,ou=People,dc=example,dc=com");) ``` * Search ACI is required to process the search filter, and to determine which attributes and values the server returns. The `search` permission allows particular attributes in the search filter. The `read` permission allows particular attributes to be returned. If `read` permission is allowed to any attribute, the server automatically allows reads of the `objectClass` attribute. For example, this ACI lets `uid=bjensen,ou=People,dc=example,dc=com` search for `uid` attributes, and read that attribute in matching entries: ```ldif aci: (targetattr = "uid")(version 3.0;acl "Search and read uid"; allow (search, read) (userdn = "ldap:///uid=bjensen,ou=People,dc=example,dc=com");) ``` * Use Control or Extended Operation The ACI must allow the `read` permission to the `targetcontrol` or `extop` OIDs. For example, this ACI lets `uid=bjensen,ou=People,dc=example,dc=com` use the Persistent Search request control with OID `2.16.840.1.113730.3.4.3`: ```ldif aci: (targetcontrol = "PSearch") (version 3.0;acl "Request Persistent Search"; allow (read) (userdn = "ldap:///uid=bjensen,ou=People,dc=example,dc=com");) ``` ## Default global ACIs | | | | - | ---------------------------------------------------------------------------------------------------------- | | | ACIs are for directory servers. For proxy servers, use [global policies](#global-access-control-policies). | Modifying and removing global ACIs can have deleterious effects.

For proxy servers, use [global policies](#global-access-control-policies). | As the number of ACIs increases, it can be difficult to understand what rights a user actually has. The Get Effective Rights control (object identifier (OID) *(tooltip: \
\

A hierarchical string of digits and dots to uniquely identify an object.\

\
)* `1.3.6.1.4.1.42.2.27.9.5.2`) lets you display the rights the server grants. By default, only users who can bypass ACIs can use the Get Effective Rights control, and the related operational attributes, `aclRights` and `aclRightsInfo`. The following command grant access to My App: ```console $ dsconfig \ set-access-control-handler-prop \ --hostname localhost \ --port 4444 \ --bindDN uid=admin \ --bindPassword password \ --add global-aci:\(targetcontrol=\"EffectiveRights\"\)\ \(version\ 3.0\;acl\ \"Allow\ My\ App\ to\ get\ effective\ rights\"\;\ allow\(read\)\ userdn=\"ldap:///cn=My\ App,ou=Apps,dc=example,dc=com\"\;\) \ --add global-aci:\(targetattr=\"aclRights\|\|aclRightsInfo\"\)\(version\ 3.0\;\ acl\ \"Allow\ My\ App\ to\ read\ effective\ rights\ attributes\"\;\ allow\ \(read,search,compare\)\ userdn=\"ldap:///cn=My\ App,ou=Apps,dc=example,dc=com\"\;\) \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --no-prompt ``` In this example, Babs Jensen owns the LDAP group that includes people who are willing to carpool: ```console $ ldapsearch \ --hostname localhost \ --port 1636 \ --useSsl \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --bindDN "uid=bjensen,ou=people,dc=example,dc=com" \ --bindPassword hifalutin \ --baseDN "ou=Self Service,ou=Groups,dc=example,dc=com" \ "(cn=Carpoolers)" ``` > **Collapse: Show output** > > ``` > dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com > objectClass: top > objectClass: groupOfNames > description: People who are willing to carpool > cn: Carpoolers > owner: uid=bjensen,ou=People,dc=example,dc=com > member: uid=bjensen,ou=People,dc=example,dc=com > ``` When My App does the same search with the get effective rights control, and requests the `aclRights` attribute, it gets the rights it has on the entry: ```console $ ldapsearch \ --control effectiverights \ --hostname localhost \ --port 1636 \ --useSsl \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --bindDN "cn=My App,ou=Apps,dc=example,dc=com" \ --bindPassword password \ --baseDN "ou=Self Service,ou=Groups,dc=example,dc=com" \ "(cn=Carpoolers)" \ aclRights ``` > **Collapse: Show output** > > ``` > dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com > aclRights;entryLevel: add:1,delete:1,read:1,write:1,proxy:1 > ``` When My App requests the `aclRightsInfo` attribute, the server shows the ACIs that apply: ```console $ ldapsearch \ --control effectiverights \ --hostname localhost \ --port 1636 \ --useSsl \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --bindDN "cn=My App,ou=Apps,dc=example,dc=com" \ --bindPassword password \ --baseDN "ou=Self Service,ou=Groups,dc=example,dc=com" \ "(cn=Carpoolers)" \ aclRights \ aclRightsInfo ``` > **Collapse: Show output** > > ``` > dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com > aclRights;entryLevel: add:1,delete:1,read:1,write:1,proxy:1 > aclRightsInfo;logs;entryLevel;add: acl_summary(main): access allowed(add) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NULL) to (cn=My App,ou=Apps,dc=example,dc=com) (not proxied) ( reason: evaluated allow , deciding_aci: Proxied authorization for apps) > aclRightsInfo;logs;entryLevel;delete: acl_summary(main): access allowed(delete) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NULL) to (cn=My App,ou=Apps,dc=example,dc=com) (not proxied) ( reason: evaluated allow , deciding_aci: Proxied authorization for apps) > aclRightsInfo;logs;entryLevel;proxy: acl_summary(main): access allowed(proxy) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NULL) to (cn=My App,ou=Apps,dc=example,dc=com) (not proxied) ( reason: evaluated allow , deciding_aci: Proxied authorization for apps) > aclRightsInfo;logs;entryLevel;read: acl_summary(main): access allowed(read) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, objectClass) to (cn=My App,ou=Apps,dc=example,dc=com) (not proxied) ( reason: evaluated allow , deciding_aci: Anonymous read and search access) > aclRightsInfo;logs;entryLevel;write: acl_summary(main): access allowed(write) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NULL) to (cn=My App,ou=Apps,dc=example,dc=com) (not proxied) ( reason: evaluated allow , deciding_aci: Proxied authorization for apps) > ``` To request effective rights for another user, use the `--getEffectiveRightsAuthzid` option. This option takes the authorization identity of the user as an argument. The following example shows My App checking Babs's rights to the same entry: ```console $ ldapsearch \ --getEffectiveRightsAuthzid "dn:uid=bjensen,ou=People,dc=example,dc=com" \ --hostname localhost \ --port 1636 \ --useSsl \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --bindDN "cn=My App,ou=Apps,dc=example,dc=com" \ --bindPassword password \ --baseDN "ou=Self Service,ou=groups,dc=example,dc=com" \ "(cn=Carpoolers)" \ aclRights ``` > **Collapse: Show output** > > ``` > dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com > aclRights;entryLevel: add:0,delete:1,read:1,write:0,proxy:0 > ``` The following example checks anonymous user rights to the same entry. Notice that the authorization identity for an anonymous user is expressed as the empty DN: ```console $ ldapsearch \ --getEffectiveRightsAuthzid "dn:" \ --hostname localhost \ --port 1636 \ --useSsl \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --bindDN "cn=My App,ou=Apps,dc=example,dc=com" \ --bindPassword password \ --baseDN "ou=Self Service,ou=groups,dc=example,dc=com" \ "(cn=Carpoolers)" \ aclRights ``` > **Collapse: Show output** > > ``` > dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com > aclRights;entryLevel: add:0,delete:0,read:1,write:0,proxy:0 > ``` To check access to a potentially nonexistent attribute, use the `--getEffectiveRightsAttribute` option. This option takes a comma-separated attribute list as an argument. The following example checks Andy Hall's access to the member attribute for the Carpooler's group entry: ```console $ ldapsearch \ --getEffectiveRightsAuthzid "dn:uid=ahall,ou=People,dc=example,dc=com" \ --getEffectiveRightsAttribute member \ --hostname localhost \ --port 1636 \ --useSsl \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --bindDN "cn=My App,ou=Apps,dc=example,dc=com" \ --bindPassword password \ --baseDN "ou=Self Service,ou=groups,dc=example,dc=com" \ "cn=Carpoolers" \ aclRights ``` > **Collapse: Show output** > > ``` > dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com > aclRights;entryLevel: add:0,delete:0,read:1,write:0,proxy:0 > aclRights;attributeLevel;member: search:1,read:1,compare:1,write:0,selfwrite-add:1,selfwrite-delete:1,proxy:0 > ``` ## Proxy global policies | | | | - | ------------------------------------------------------------------------------------------ | | | Global policies are for directory proxy servers. For directory servers, use [ACIs](#acis). | By default, a policy matches all entries, all types of connection, and all users. You set the properties of the policy to restrict its scope of application. Global access control policies can allow the following: * Requests for specified LDAP controls and extended operations. * Access to specific attributes, with support for wildcards, @objectclass notation, and exceptions to simplify settings. * Read access (for read, search, and compare operations). * Write access (for add, delete, modify, and modify DN operations). * Requiring authentication before other requests. * Requests targeting a particular scope, with wildcards to simplify settings. * Requests originating or not from specific client addresses or domains. * Requests using a specified protocol. * Requests using a specified port. * Requests using a minimum security strength factor. * Requests from a user whose DN does or does not match a DN pattern. ### Default global policies Access control rules are defined using individual access control policy entries. A user's access is defined as the union of all access control rules that apply to that user. In other words, an individual access control rule can only grant additional access and can not remove rights granted by another rule. This approach results in an access control policy which is easier to understand and audit, since all rules can be understood in isolation. | Policy | Settings | | --------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Anonymous extended operation and control access | * `authentication-required` * `false` * `allowed-extended-operation` * `Cancel` * `GetSymmetricKey` * `PasswordModify` * `StartTLS` * `WhoAmI` * `allowed-control` * `Assertion` * `MatchedValues` * `NoOp` * `PasswordQualityAdvice` * `PermissiveModify` * `PostRead` * `PreRead` * `RealAttrsOnly` * `SimplePagedResults` * `VirtualAttrsOnly` * `AuthorizationIdentity` * `PasswordPolicy` * `TransactionId` * `Vlv` * `W3cTraceContext` | | Authenticated extended operation and control access | - `authentication-required` * `true` - `allowed-extended-operation` * `PasswordPolicyState` - `allowed-control` * `ManageDsaIt` * `SubEntries` * `RelaxRules` * `SubtreeDelete` * `ServerSideSort` | | Schema access | * `authentication-required` * `true` * `request-target-dn-equal-to` * `cn=schema` * `permission` * `read` * `allowed-attribute` * `objectClass` * `@subschema` * `etag` * `ldapSyntaxes` * `modifiersName` * `modifyTimestamp` | | Root DSE access | - `authentication-required` * `false` - `request-target-dn-equal-to` * `""` - `permission` * `read` - `allowed-attribute` * `objectClass` * `namingContexts` * `subSchemaSubEntry` * `supportedAuthPasswordSchemes` * `supportedControl` * `supportedExtension` * `supportedFeatures` * `supportedLDAPVersion` * `supportedSASLMechanisms` * `supportedTLSCiphers` * `supportedTLSProtocols` * `vendorName` * `vendorVersion` * `fullVendorVersion` * `alive` * `healthy` | | Monitor access | * `authentication-required` * `true` * `request-target-dn-equal-to` * `cn=monitor` * `permission` * `read` * `allowed-attribute` * `*` * `+` | ### Reject unauthenticated requests The following example uses a single broad policy for authenticated access, and another narrow policy for anonymous extended operation access: > **Collapse: Show commands** > > Global access control policies are for proxy servers only.

This effectively permits only secure connections for requests targeting data in `dc=example,dc=com`. The security strength factor defines the key strength for GSSAPI, SSL, and TLS. | | | | - | ------------------------------------------------------------------------------------------ | | | Global access control policies are for proxy servers only. Use ACIs for directory servers. | ```console $ dsconfig \ create-global-access-control-policy \ --hostname localhost \ --port 4444 \ --bindDN uid=admin \ --bindPassword password \ --policy-name "Require secure connections for example.com data" \ --set request-target-dn-equal-to:"**,dc=example,dc=com" \ --set request-target-dn-equal-to:dc=example,dc=com \ --set connection-minimum-ssf:128 \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --no-prompt ``` ### Anonymous requests from specific network The following example allows anonymous requests from clients in the `example.com` domain. | | | | - | ------------------------------------------------------------------------------------------ | | | Global access control policies are for proxy servers only. Use ACIs for directory servers. | ```console $ dsconfig \ set-global-access-control-policy-prop \ --hostname localhost \ --port 4444 \ --bindDN uid=admin \ --bindPassword password \ --policy-name "Anonymous extended operation access" \ --set connection-client-address-equal-to:.example.com \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --no-prompt $ dsconfig \ set-global-access-control-policy-prop \ --hostname localhost \ --port 4444 \ --bindDN uid=admin \ --bindPassword password \ --policy-name "Root DSE access" \ --set connection-client-address-equal-to:.example.com \ --trustStorePath /path/to/opendj/config/keystore \ --trustStoreType PKCS12 \ --trustStorePassword:file /path/to/opendj/config/keystore.pin \ --no-prompt ``` You can also use the `connection-client-address-not-equal-to` property to reject requests from a particular host, domain, address, or address mask.
