I am missing the samba domain object from my server container. I cannot figure out how to recreate the object. I verified the schema is extended and tried to reinstall samba through Yast. What am I missing?

SLES 10.1

Lum is enbaled and working as far as I can tell. The users are members of a Lum enabled group and are samba enabled. I am getting an authentication error when the user logs in. I'm guessing this is because of the missing Domain object. When I look at the sambaSID attribute on my user it is showing a value of -601. Is this correct? Is this possibly wrong because the domain object is missing?
