Setting up PDC and BDC using Samba

[Gerry Kirk]

Is this possible? Can I use Samba 2.0.x or do I need TNG? I think I saw an 
email back from someone who suggested that the only difference between a 
PDC and a BDC is that the BDC references the PDC as the password server. My 
question to that is what if the PDC is down? The BDC should be able to take 
over the responsibilities of the PDC.

Thanks in advance,
Gerry
