I wonder how winbind accomplishes this, maybe it does the lookups and cross references you mentioned.. which is probably why it's so slow by comparison to ldap ;)

Thanks for all the help Paul. It's just too bad that Windows uses the full name to create the user dn by default which is really the cause of the problem.. Now I just need to find out who it was that wrote that chunk of code in AD ;)
