Description Peter Rindfuss 2009-04-15 03:59:46 UTC
After upgrading from Samba 3.2.8 to 3.2.10, domain logins do not work correctly anymore for Windows XP clients that do not have SP3 installed.

Environment: OpenSUSE 11.0 PDC and BDC with Samba 3.2.10 and OpenLDAP. Clients are Windows XP Pro with SP3 or SP2.

Symptoms: After login, an lsass.exe error is displayed, and windows starts shutting down (60 secs left). This happens reproducibly with all Windows XP SP2 clients. If I stop the shutdown, I can work with the mounted shares. If I open, however, the control panel system properties "computer name" tab, a popup tells me that there is no RPC server, and the domain name is "*unknown*". There are some more symptoms.

It is possible to log locally into a computer, to mount shares on the PDC manually and to work normally with them. The problem seems to be related to domain and/or security functions, not to file services.

I downgraded the PDC and the BDC to 3.2.8, and with that, everything is fine again. This unfortunately means that I cannot do any testing.

Ok, here is a reverse diff of changes in the rpc_server subsystems between 3.2.8 (which works) and 3.2.10 (which doesn't). Could you apply this patch to 3.2.10 and see if the clients start working again ?

If they do, then let's narrow down which change it was that caused the problem. My guess would be the changes in rpc_server/srv_netlogon_nt.c which were added to allow us to cope with upcoming Windows 7 code. So you could try swapping the 3.2.8 and 3.2.10 versions of that file into 3.2.10 and seeing if that fixes the issue.

Your help on this would be greatly appreciated !


Comment 2 Peter Rindfuss 2009-04-15 13:45:24 UTC

I'd be happy to help, but

- I have no testing environment
- We are talking about our central server (up to 450 workstations attached)
- I usually do not compile Samba, but apply opensuse binaries.

But I could try on Saturday (April 18) afternoon, if that is soon enough,
and if I manage to modify and compile the opensuse source rpm.

Best, Peter

Jeremy, I know what is going on and I am able to reproduce.
Comment 5 Guenther Deschner 2009-04-15 18:58:08 UTC
Thanks for the diff Jeremy, that really helped :)

A fix for this is pushed to all branches:



Everyone please test.

Patch for 3.2.x.

In case people can't get to git, here is Guenther's patch as an attachment for 3.2.x.

I am having the exact same error on Vista Business 32bit w/ SP1 and all updates installed.  I thought it was a bad Windows Update pushed out by Microsoft (our WSUS server pushes out all updates automatically).  My only solution was to go in to safe mode as administrator, open a cmd prompt and run:

net stop winmgmt /y
del /s /q c:\windows\system32\wbem\Repository\*.*

and then reboot.  But now that you mention it, I was only getting that error after I joined the Vista clients to my domain.

Comment 8 Guenther Deschner 2009-04-16 18:49:12 UTC
Just verified with Vista: 

And yes, without typing or pressing anything, Vista SP1 gets into an infinite  crashe and reboot loop. The fix that has been published and pushed resolves this. We also made sure in our automated testsuite that this never happens again.

If we could have any further positive feedback we could close this bug.
Comment 9 Peter Rindfuss 2009-04-18 11:40:54 UTC
3.2.11 works fine with WinXP / SP2.
Cheers, Peter
Comment 10 Guenther Deschner 2009-04-18 20:05:43 UTC
Thanks for verifiying, Peter.

Closing as fixed.
