Unable to find Subdomain users


We have a openfire setup working perfectly fine with the baseDN specified dc=“Domain”,dc=“Com”.

However we have recently added a new Subdomain in AD as Subdomain.domain.com.

In Openfire I have added ldap.alternatebasedn as dc=“Subdomain”,dc=“Domain”,dc=“Com”.

Still i cannot find the users in the user list, nor i can find any mechanism to authenicate them.

Please help me out as I have tried almost all possible option as i could find in the discussion group.
