Locating a user’s group memberships in Lightweight Directory Access Protocol

WebSphere Application Server security can be configured to search group memberships directly or indirectly. It can also be configured to search only a static group, or it can be configured to search static groups, recursive or nested groups, and dynamic groups for some Lightweight Directory Access Protocol (LDAP) servers.

 

Procedure

 

Results

While using the direct method, dynamic groups, recursive groups, and static groups can be returned as multiple values of a single attribute. For example, in IBM Directory Server all group memberships, including the static groups, dynamic groups, and nested groups, can be returned using the ibm-allGroups attribute. In Sun ONE, all roles, including managed roles, filtered roles, and nested roles, are calculated using the nsRole attribute. If an LDAP server can use the nsRole attribute, dynamic groups, nested groups, and static groups are all supported by WebSphere Application Server.

Some LDAP servers do not have recursive computing functionality. For example, although Microsoft Active Directory server has direct group search capability using the memberOf attribute, this attribute lists the groups beneath, which the group is directly nested only and does not contain the recursive list of nested predecessors. The Lotus Domino LDAP server only supports the indirect method to locate the group memberships for a user. You cannot obtain recursive group memberships from a Domino server directly. For LDAP servers without recursive searching capability, WAS security provides a recursive function that is enabled by clicking Perform a Nested Group Search in the Advanced LDAP user registry settings. Select this option only if your LDAP server does not provide recursive searches and you want a recursive search.
