Configuring LDAP Nested Group Extraction

Last published : Sep 03, 2026
NetScaler Gateway can query LDAP groups and extract group and user information from ancestor groups that you configure on the authentication server. For example, you created group1 and within that group, you created group2 and group3. If the user belongs to group3, NetScaler Gateway extracts information from all the nested ancestor groups (group2, group1) up to the specified level.
You can use an authentication policy to configure LDAP nested group extraction. When the query is run, NetScaler Gateway searches the groups until it reaches the maximum nesting level or until it searches all available groups.
