The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Nested LDAP Group Search for Microsoft AD feature allows you to retrieve the complete nested-user-group chain information of a user in a particular Microsoft Active Directory domain.
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release.

Nested Lightweight Directory Access Protocol (LDAP) group search supports nested-group searches only in Microsoft Active Directory (AD) on Windows Server 2003 and later versions. This feature does not support searches in generic LDAP servers.
The Lightweight Directory Access Protocol (LDAP) search query is used to retrieve a user’s authorization profile from an LDAP server to find direct user group members. Each of these direct user groups can be part of multiple groups and thus form a nested-user group.
To find nested-user groups on an LDAP server, an LDAP client must send multiple queries to the LDAP server. Hence, excessive system and network resources are required to find nested-user groups.
Instead of sending multiple LDAP queries, an LDAP client uses a customized, Microsoft-supported search filter to perform a server-based search to find all the non-primary nested groups to which a user belongs. To limit the number of user groups found by Microsoft Active Directory (AD), you can configure a base distinguished name (DN) configuration within the limit you require.
Perform this task to configure a search request sent by a Lightweight Directory Access Protocol (LDAP) client to a server to find a user’s nested-group information in Microsoft Active Directory (AD).
