[Samba] migration of PDC tdbsam backend to BDC - failed to fetch domain database

[Gaiseric Vandal]

What version of samba?

The "vampire"  command can be used to pull account info from an NT4 
server into a Samba 3.x domain.  I am not sure if it can be used against 
a Samba 3.x server.  I could be wrong.   Samba 4 would be a different 
situation.

You may be able to copy the samba private and samba locks directories 
over from PDC to BDC instead.
