Hi,

AFAIK, BDC is a term taken from the NT4 world. Since Windows2k there are no
more PDC and BDC, only DC. So, all DCs in your domain should contain the
same data and do the same work. This should give you HA as well as
load-balancing.

Anyhow, I'm not a windows guru, so you might want to ignore my last
statement and seek for a better advice :)

Hello,

I kept hearing that Samba 3 can join and do anything as a Windows
Domain Controller even better than Windows itself.

But now that I need it to replace a Backup Domain Controller (fka
Secondary Domain Controller?) to a Windows 2003 Active Directory
server I keep bumping into the following worrying FAQ:

Can Samba Be a Backup Domain Controller to an NT4 PDC?

  No. The native NT4 SAM replication protocols have not yet been fully
implemented.

Can I get the benefits of a BDC with Samba?  Yes, but only to a Samba
PDC.The main reason for implementing a BDC is availability. If the PDC
is a Samba machine, a second Samba machine can be set up to service
logon requests whenever the PDC is down.

And I'm not sure how relevant this is for my situation - is Windows
2003 considered "NT4 PDC" or is it something newer that Samba can
cooperate with as a BDC?

Also the Samba online documents seem to come up with lots of stuff
about 2.2, if Samba 3 CAN be a BDC for Windows 2003 and there is a
good document on how to do this then I'd appreciate very much a direct
pointer to such docs. I have the Samba HOWTO printed book from around
2.5 years ago but I'm not sure how relevant this is for today.

Thanks,
