Samba PDC troubles

[Fredrik Tolf <fredrik@dolda2000.com>]

Hi list!

I've been playing a little with Samba lately, trying to make it a PDC
for a network of Windows computers (no, I don't particularly want them,
but it's kind of out of my hands), and I'm having some trouble. I hope
there's someone more knowledgeable than I with Samba who knows what
might be causing this.

See, to play around a bit, I set up a virtual network with an Etch
server and two XP clients running as KVM guests, and I managed to get it
all working as it should and as I want it, but when I try it out on the
real machine where it's supposed to be running, I can't get the
workstations to join it. The problem is that Samba isn't running as root
when it runs the "add machine script" and trying to do the actual work
of adding the workstation to the tdbsam database, so it gets permission
errors.

I can't find that I've configured the two machines differently in any
way that would matter, though. I've set up group mappings in the same
way, and I've verified that the user I'm logging in as to add the
machines is in Samba's "Administrators" group (which I've mapped to the
"adm" group on both the test server and the real server).

Does anyone know what could cause such behavior?

Thanks for reading!
