Brought in a new Windows 7 64-bit machine and that one works... So it
seems to be a Windows configuration issue, but what other settings could
possibly cause this authentication failure? The new machine is a recent
clean install and uses MSE as antivirus, whereas the older workstations
use AVG and Ad-Aware. But I doubt the antivirus could cause the
difference. And I don't see any difference in the network configuration
of the machines. Any suggestions? I can't simply replace all Windows
clients on our network...

Hi,
When I try a net logon from Windows 7 64-bit Business (don't have any
other Windows machines), I get "The trust relationship between this
workstation and the primary domain failed". The discussion I've found
around the Web regarding this error message seems to be only in the
context of the 30 day password expiry issue, where the solution is to
simply rejoin the domain. Unfortunately, I have this problem *always*,
and rejoining does not help. I have not been able to do a net login at
all, from the first time I tried. At the same time, there's no problem
accessing the Samba shares by going to \\SMB in Windows Explorer and
logging in with the same user accounts.
# smbstatus
Samba version 3.6.7-48.12.1-2831-SUSE-SL12.2-x86_64
The LAN is on 172.16. and the Samba machine is also the LAN's DNS
server; not using LDAP.
We had been using Samba for simple file sharing, with no domain
functionality enabled, and with the Windows machines on the network
configured as members of the workgroup. We recently decided to set
Samba as a PDC and support roaming profiles, and have been blocked by
this trust error.
I made some changes to smb.conf, which can be seen here:
http://pastebin.com/raw.php?i=qKvQq3W2
The profiles directory was chmod 2775 and its group changed from root
to users. The netlogon directory is 755. Initially, in smb.conf the
name resolve order was starting with dns, but Windows 7 kept giving me
an error about not finding the domain when I tried to change from
workgroup to domain, so I took that out and set wins as the first item
in the list.
# cat /etc/samba/smbusers:
root = administrator Administrator admin
nobody = guest pcguest smbguest
I added root to smbpasswd. I also executed the following:
net groupmap add ntgroup="Domain Admins" unixgroup=root rid=512 type=d
net groupmap add ntgroup="Domain Users" unixgroup=users rid=513 type=d
net groupmap add ntgroup="Domain Guests" unixgroup=nobody rid=514 type=d
net rpc rights grant -U root "URBASE\Domain Admins"
SeMachineAccountPrivilege SePrintOperatorPrivilege SeAddUsersPrivilege
SeDiskOperatorPrivilege SeRemoteShutdownPrivilege
The Windows machines are configured as specified on
wiki.samba.org/index.php/Windows7 (that is, I only edited
DomainCompatibilityMode and DNSNameResolutionRequired). Changing from
workgroup to domain and rebooting, then trying to log in with one of
the SMB users gives me the "The trust relationship between this
workstation and the primary domain failed" error. I can only log into
the local machine account. If, instead of changing from workgroup to
domain directly, I try to use the network ID wizard, it eventually
leads to the same error when it tries to set up the domain user.
Looking at /etc/samba/smbpasswd, the machine account shows up there so
the add machine script seems to be working; however,
# tail /var/log/samba/log.smbd

Why is it not working? I don't know how to troubleshoot this. I've
tried removing the machine from the domain then taking it out of
smbpasswd and the Unix accounts, and then rejoining, but same errors.
I tried manually adding the IP address in the Windows machine's WINS
setting, but it doesn't make a difference.
One thing I'm unsure of is the DNS suffixes thing which seems to be
mentioned on some sites in association with this. In the Windows
clients, under "Append these DNS suffixes (in order)" we've normally
had as suffix the DNS master zone for the LAN, which is different from
the domain name in smb.conf -- if that matters at all given joining
the domain should be using WINS instead of DNS for name resolution. I
tried adding the domain in there anyway, but it doesn't help.
Can anyone kindly help? I've asked on a couple of other forums but to
no avail...
