I think you need to chase down a member of the Windows team and find
out why the dns is weird (the functional level isn't a problem on a
Unix domain member).
Active Directory relies heavily on dns, so anything that connects to AD
should be using the same dns domain.
You shouldn't need to set 'password server', Samba should find the best
DC to use, but this relies on dns.
