The search filter must use the username or the DN to find the user's groups. This is done via [variable substitution](#variable-substitution-in-configuration-strings).

A group's DN may be associated with an [access policy](#managing-usergroup-access-policy).

#### Nested groups usage in LDAP/AD
If you are using Active directory with nested groups you have to add LDAP_MATCHING_RULE_IN_CHAIN: :1.2.840.113556.1.4.1941: to your query.
