Samba 2.2.3 works as PDC, not shure if M$ can act as BDC then.

I am not sure how well this will work, using linux ad a pdc and a windows 2k box as a bdc.  In windows 2000, the concept of pdc adn bdc are gone.

Information from the samba 2.2.x pdc howto(http://bioserve.latrobe.edu.au/samba/samba-pdc-howto.html):

What can't we do ?

     Become or work with a Backup Domain Controller (a BDC).

     Participate in any sort of trust relationship (with either Samba or NT Servers).

     Offer a list of domain users to User Manager for Domains on the Security Tab etc).

     Be a W2K type of Domain Controller. Samba PDC will behave like an NT PDC, W2K workstations connect in legacy mode.

Sorry,  I wish i had good news...

The main reason for having a BDC is that you can not backup an NT4-style Domain otherwise.

As you can easily backup the Samba configfile under Linux it is not really necessary to have a BDC.

Another reason might be load-balancing, but unless your network is very hugh this shouldn't be an issue either.

So you might want to reconsider the need for a BDC because, as mhonomichl said, Samba can't do it.

If you still need it, there us a "spin-off" to the "classic" Samba Development called Samba TNG:

Samba-TNG ist more "experimental" in it's development, thus it has more features but might lack stability ...!?

From some articles I have the impression they have BDC Support:

"b) Backup Domain Controller
Support for a Samba BDC is very unstable and could possibly do nasty
things. Most sane people people should avoid it.
Now, for the rest of us, we need to follow some steps similar to the
Workstation section above: [...]"

In response to Zook's reply:

The point of having a BDC is not only for redundancy of the PDC, but it also is used in a WAN configuration to save on Bandwidth via not having to authenticate over a Frame for example.  If the Frame goes down, the BDC provides the user the ability to still authenticate at the local site the BDC resides on regardless of connectivity to a PDC at the parent site on the other end of the Frame Connection.  This being the case, the only loss of functionality the BDC site would have is the inability for users to change passwords.

I agree with the grading for zook.

But keep in mind that this is an old question, and software became better now, for example http://www.samba-tng.org might be a choice for the original question.
