Can't you just disable winbind from nssswitch  ?

Do you have a PDC with the same setup?

The PDC is a Windows 2000 (sic!) server. I cannot change that.

Are you syncing uid/gid manually?

I keep Unix uid/gid on Unix and don't want any Winbind-generated uids
or gids.

All I want is a Windows user MYDOMAIN\johndoe to be mapped to the unix
user johndoe whose Unix uid is 2000 in /etc/passwd.  This is exactly
what happens when winbinnd is not started.

Now I need to run winbindd for Squid authentication. The problem is,
as soon as I start winbindd, smbd begins consulting it
so you are running smbd and winbind an squid on the same machine

Yes.


and all
Windows users start receiving uids/gids different from those in
/etc/passwd.
Thats quite normal.

Thats undesirable.


How do I prevent smbd from consulting winbindd and make
it use the old /etc/passwd mechanism for uids?
I do not know. I believe it's not possible.

Run smbd on one machine with NIS or LDAP, winbind for squid on an other
machine.


This is an obvious solution, I will do that if I find no other way.
But how does smbd communicate with winbindd? Can I hide them from each
other? is "auth methods = ntdomain" or "auth methods = trustdomain"
not what I want?

Which of the auth methods does smbd use when it cannot find a
functional winbindd?



Alternatively you may try to run winbind with an own smb.conf

This may be a good idea but how do I hide winbindd (even running with
its own smb.conf) from smbd? How does it communicate with smbd?


if you wish to try this, you may start with a new setup.
I have done this tree times with LDAP as backend, it works. If you need
more details, I can write a step-by-step guide, maybe next week.

I don't need a  step-by-step guide but I would appreciate an
explanation how to hide smbd and winbindd from each other other than
running them on different hosts.
