Comment 51 for bug 1572122

Ok, so here are some more complete information for how to reproduce the problem.

Have a samba3x server running as a PDC, with windows stations joined on the domain

[root@el5 ~]# rpm -qa samba\* \*smb\* \*talloc\* \*tdb\* \*ldb\* \*tevent\* \*wbclient\*
libtevent-0.9.18-2.el5
samba3x-client-3.6.23-9.el5_11
samba3x-common-3.6.23-9.el5_11
libtalloc-2.0.7-2.el5
hsqldb-1.8.0.9-1jpp.3
samba3x-winbind-3.6.23-9.el5_11
libtdb-1.2.10-1.el5
samba3x-3.6.23-9.el5_11
tdb-tools-1.2.10-1.el5
libsmbclient-3.0.33-3.40.el5_10
[root@el5 ~]#

See the attached smb.conf file for the relevant sections of my config (I just removed my shares definition as it most likely is not relevant)

One client is member of the NT4 domain. It's a Windows 7 pro box (name: win7, IP: 192.168.7.12)

I can log into this box with no problem, see the win7_ok.log file, which traces a successful login from this box using a domain account.

I now update the different packages:

yum update samba\* libsmb\*

Full transaction:

Updating:
 libsmbclient i386 3.0.33-3.41.el5_11
 samba3x i386 3.6.23-12.el5_11
 samba3x-client i386 3.6.23-12.el5_11
 samba3x-common i386 3.6.23-12.el5_11
 samba3x-winbind i386 3.6.23-12.el5_11

Now:

[root@el5 ~]# rpm -qa samba\* \*smb\* \*talloc\* \*tdb\* \*ldb\* \*tevent\* \*wbclient\*
libtevent-0.9.18-2.el5
samba3x-client-3.6.23-12.el5_11
samba3x-winbind-3.6.23-12.el5_11
libtalloc-2.0.7-2.el5
hsqldb-1.8.0.9-1jpp.3
libsmbclient-3.0.33-3.41.el5_11
samba3x-3.6.23-12.el5_11
libtdb-1.2.10-1.el5
tdb-tools-1.2.10-1.el5
samba3x-common-3.6.23-12.el5_11
[root@el5 ~]#

After restarting the smbd daemon, I can no longer open a session using a domain account. On the client computer, I get a message stating that the trust relationship between this station and the domain failed (the exacte message in french is "La relation d'approbation entre cette station de travail et le domaine a échoué.")

See the file win7_ko.log for the server-side logs when I try to login.
