Description Koala Yeung 2010-01-04 05:01:53 UTC
I have a Samba domain of Windows XP.
I tried to have a new Windows 7 PC join the Samba domain.
And I failed to logon, as any account, on that PC.
It says that either my user name or password is incorrect.

I checked by log, and this seems to be related:
------------------------------
[2010/01/04 17:49:13,  2] libsmb/credentials.c:223(netlogon_creds_server_check)
  netlogon_creds_server_check: credentials check failed.

Hallo,

have you change the registry on then windows 7 machine?:

HKLM\System\CCS\Services\LanmanWorkstation\Parameters
            DWORD  DomainCompatibilityMode = 1
            DWORD  DNSNameResolutionRequired = 0

Have you change the user over the button "other user" (or similary - i havn't a english windows) to domain-users?

On my installations logon are possible, but in logfiles the error-messages was similary: 
Rejecting auth request from client CLIENT-PC machine account CLIENT-PC$

I found out, that all machine-names use lower letters in /etc/passwd and /var/lib/samba/passwd.tdb. If in /etc/passwd the same entry in uppercase the errormessages disappears. So I create a workarround:

Frist create a file /usr/sbin/maschineadd:
#!/bin/bash
gross=$(echo $* | /usr/bin/tr a-z A-Z)
/usr/sbin/useradd -s /bin/false -d /dev/null -g 515 $gross

second change in smb.conf:
 add machine script = /usr/sbin/machineadd %u

Hint: You must have a group 515 (Domain-Computers).
Then delete the old entries in /etc/passwd and /var/lib/samba/passwd.tdb

pdbedit -x CLIENT-PC$
userdel CLIENT-PC$

and get domain-member from the client-pc-side. It should create the names in capital letters and the error-message disappears. I hope your login-problem too.

with regards
Andreas Matthus

Sorry to confirm that the add machine script work rounds here do not work here.

I actually had a windows 7 ultimate PC working in a Samba 3.4 domain earlier in the year. As of this week profiles failed to load. 

The usual fix to remove all traces of the client in the domain and re-add the client back into the domain are failing to create a valid machine account. This is logged:

[2010/09/09 16:50:31,  0] rpc_server/srv_netlog_nt.c:603(_netr_ServerAuthenticate3)
  _netr_ServerAuthenticate3: netlogon_creds_server_check failed. Rejecting auth request from client W7 machine account W7$

As such none of the users can login to the Windows 7 client with these logs:

[2010/09/09 16:52:53,  1] smbd/service.c:1063(make_connection_snum)

Samba version is 3.4.8 from Debian backports.

if this does not work this is most probably a client registry setting fault.
