	Samba is your PDC and W2k3 is a Member Server and is already
joined the domain. The W2k3 is able to access the Samba3 shares? Did
you disable "Require Sign or Seal" (I'm not sure if it is needed on

	What MS TechNet says about error 1789? (don't you love this

	But did you use net groupmap?

	Which minor? 3.0.X where X is?

	Hmmmm... winbind goes in the other direction, brings user list
from another host (samba or windows) to samba. Still looks like a
permission problem. Even if the w2k3 has joined the domain, apparently
it didn't reconigze the Samba as PDC or it couldn't bind it (permission

	As you said, turning it to workgroup works, so it should be a
domain join/bind related problem.
