Memberofindirect processing of an entry doesn't work if the user doesn't have rights to any one of these attributes: - member - memberuser - memberhost Add all of these to any read permission that specifies any of them. Add a check to makeaci that will enforce this for any future permissions. Reviewed-By: Martin Kosek <mkosek@redhat.com>
