Ok, thank you for explanation. But I still do not understand why squid_ldap_group does not work without -R option. And how to force it to make a real request to PDC, not just serch top-level groups...

That's not referrals, at least not from what i know of referrals... referrals is for redirecting the requestor when LDAP objects or subtrees found in another LDrAP server.. used for example in a global LDAP directory server used for finding each organisations LDAP directory servers.. Can you use ldapsearch to search for those sub-members? Regards Henrik
