Description Karsten 2008-04-01 09:12:44 UTC
Hi together,

i am trying to implement a samba-server version 3.0.25c in a big corporate network
with thousands of user.
It is running under Solaris 5.10 on a SUN SPARC.

We want to give special users some samba-shares for delivering files for a
production system.
The users are not existing as unix-user and must be authenticated through active
WinBindd is running, but we use a direct mapping with username map=

The configuration looks like this:
        security = SERVER
        encrypt passwords = Yes
        password server = localdomain1 foreigndomain1 localdomain2 localdomain3
        username map = /.../cfg/smbusers.map
        log level = 5
        syslog = 0
        smb passwd file = /.../samba/smbpasswd
        auth methods = trustdomain winbind
        wins support = no
        wins server = localdomain1 localdomain2
        winbind separator = +
        idmap uid = 100000-200000
        idmap gid = 100000-200000
        winbind enum users = yes
        winbind enum groups = no

Most of the users are defined in the local domain GSA-NET and samba is working fine.
This users are authenticated without any problem.

The PROBLEM are users that are coming from an other domain. This user FAIL.

  check_ntlm_password:  mapped user is: [GSA-NET]\[xtract]@[DUFF0520]

        Why GSA-NET ?
        This is the wrong local domain !

    Here the code / function in the source:

         Routine to get the trust account password for a domain.
         The user of this function must have locked the trust password file using
         the above secrets_lock_trust_account_password().

          if (!(pass = (struct machine_acct_pass *)secrets_fetch(
                      trust_keystr(domain), &size))) {
                DEBUG(5, ("secrets_fetch failed!\n"));
                return False;

[2008/03/26 16:00:36, 5] auth/auth.c:(273)
  check_ntlm_password: trustdomain authentication for user [xtract] FAILED with

The strange thing is that this is a problem of a server migration.
The old server is running samba version 2.2.7 and on this machine the users in the
foreign domain are authenticated without no problem!

As alternate way i will try security = ADS with kerberos, but this takes much time
to implement.
I think it would be a better way to use this approved way.

The problem seems to be old, because i found this discussion with Andrew Bartlett:

12/19/05  0:13:00 <abartlet> it was 'winbind use default domain' that caused me to
try some of that
12/19/05  0:13:31 <abartlet> of course, I added the pain that is 'winbind use
default domain' (along with ab, I think...)
12/19/05  0:13:40 <vl> auth_util.c:738 is the culprit
12/19/05  0:14:54 <vl> I know that once I did print auth_util.c with a very small
12/19/05  0:15:05 <abartlet> :-)
12/19/05  0:18:01 <vl> Hmmmm. Has check_trustdomain_security ever been really used?
12/19/05  0:20:55 <abartlet> probably not, as winbindd handles that
12/19/05  0:22:34 <vl> I think I broke enough for today. auth_util must wait...
12/19/05  0:23:24 <abartlet> :-)

I would be happy for any ideas or help to solve this problem.

Found a configuration problem.
Bug not existent. Sorry.
