[Samba] Samba AD DC: LDAP Bind function call failed.

[Nick Couchman]

I've got an existing AD domain with a couple of Windows domain controllers, and I'm trying to migrate the AD domain over to Samba, or at least add a couple of Samba DCs.  I've added the samba DCs, verified that DNS is correct, and I have all the sysvol stuff replicating over between the controllers.  Things seem to be working correctly, except when I do a "gpupdate /force" on a system that has logged in to that controller, I get an error during the group policy update.  The user policy update succeeds, but the computer update fails with the following error:

The processing of Group Policy failed.  Windows could not authenticate to the Active Directory service on a domain controller.  (LDAP Bind function call failed.)

Can anyone provide any insight on why I'd be getting this error, or the steps I should take to track down the issue?  I can provide configuration files or logging, if necessary.

Thanks,
Nick
