samba - Jul 2006 - Upgrading from NT4 to Server 2003/Active Directory

Hi!

 

We're in the process of upgrading our old NT4 PDCs to 2003 Server. We
have several UNIX file servers that use Samba so Windows users can
access files store on them. Currently, we've got Samba versions running
from 2.2.7 up to 3. 

 

I've been doing some research on this, but there are some things that
are unclear to me, and I'm hoping someone can answer what I am sure are
some basic questions:

 

1)       Is it a *requirement* to upgrade all Samba servers to version
3, with ADS support compiled in? I ask because in our testing, it seemed
that if the samba server was already part of the Windows domain,
everything worked fine after the upgrade to 2003 Server. Due to
historical/legacy issues, we've had to keep older versions of Samba
around. It would be ideal not to have to upgrade the older servers (at
least in the short term...they certainly will be upgraded in the future)

2)       Are there any issues I should be aware of during our upgrade to
Active Directory? Again, our samba functionality is pretty basic -
pretty much just UNIX file access for Windows clients. 

 

Tia, sorry if these seem like basic questions (now, back to reading
samba docs!)

One issue I'm aware of is that w2k3 if configured as a DC
requires SMB signing by default. Samba 2.2 does not do it,
and I'm not 100% certain the early Samba 3 versions did it
correctly, recent 3.0 does. This means that your 2.2 servers
will not be able to connect to the DCs anymore.

There are registry settings on the DCs that remove this
requirement, but not everyone is willing to do that.
