I'm trying to setup Samba 3.0 to talk to an LDAP server for authentication, but I can't get any communication to the LDAP server from Samba when a machine attempts to join the domain. I see the machine sending out the broadcast request to join the domain, but the samba server does not respond (security = domain, domain logons = yes). Does the samba server always have to authenticate the machine joining the domain, or can it pass it off to the LDAP server? If domain logons = yes, does that mean the samba server will always authenticate the machine? If so, how do you get samba to pass off the machine authentication to the LDAP server? Rob
