Thanks for the hint.
But: This is more an NT-problem (also it turns to also have
some other issues, more below)
It is like this:
I just can't reboot the Terminalserver (it's not "mine",
also they were kind enough to give me the admin-pw, and
there are some big calculations running on it)
And the problem is, that the samba-domain is not showing up
in the listbox, when you try to log into the
>From your suggestion, I run rpcclient against the TS and
did a domlist and samba-dom was in it. So the main things
seem to work, just that listbox doesn't want to contain the
new domain. (I said, it's an nt-issue, and I guess,
rebooting will help)
Now about the samba-related stuff:
(I have to note, since it's more "production", it's
currently an older samba version, but I'm updating it while
typing this mail.)
Here's, what I did and what happened:
First off all, I remembered, that the "trusting domains"
parameter in smb.conf was useless, no code used it, so I
didn't even touch it.
So I just created an nt-dom$ in my passwd, did the
"createuser nt-dom$ -i", and "samuser nt-dom$ -p pw", then
called the admin of the nt-box to do the right stuff in
usrmgr on his pdc.
Until here, all seemed to have worked properly.
So I tried to access their boxes with smbclient /
rpcclient. This failed somehow, after some debugging,
raising log-levels and stuff like that, I got it:
The nt-pdc does some net_req_chal, but with its own name
as the "trust-account", not the name of its domain. So I
thought, "you want your name, okay, you can have that too"
and added nt-pdc$ also as an interdom-trust-account, did
set the same pw, et voila, smbclient / rpcclient worked
fine. (more on this stuff below...)
Now we come to something, that might be a problem in samba
(that's, why I'm updating it): After a while, I started to
ask myself, wether interactive logons would work anyway, so
I asked the admin of the nt-pdc to log into his pdc with
some account from the samba-domain. This failed, and NT
said something about "the trust-connection between the
primary and the trusting domain could not be set up." or
the like. I currently haven't got good logs for this, so
this is just a start of a possible "bug".
Okay, that's, where I'm currently.
So after the above nt-pdc$-action, I asked myself, wether
NT-Servers, that let other domains other domains trust it,
also had this stuff, and what it was created like, so I got
to some company with lots of nt, compiled rpcclient on a
small Sun and checked. There wasn't any nt-pdc$, just
nt-dom$. So how does NT handle this stuff? The thing, I
could imagine, would be:
trusting-pdc connects to trusted-pdc, requests chal for
trusted-pdc now does some lots of work (querying wins,
doing dclist on 138, etc.) to get a complete list of dcs for
trusting-dom and verify, that trusting-pdc is in there. and
then traet "trusting-pdc" as "trusting-dom".
I wasn't able to get any traces from pdc-to-pdc in that
company (I was glad, I could run rpcclient towards theier
