Description Giuseppe Sacco 2009-11-09 03:27:36 UTC 
I setup a new x86_64 machine with SUSE Linux Enterprise Server 10. Then I downloaded latest samba from http://download.opensuse.org/repositories/network:/samba:/STABLE/SLE_10/x86_64 and installed it (package version is 3.4.3-1.1.) Packages I installed are for both 64 bit (native) and ia32 (for 32bit application). I then joined the domain, using yast2, and tried if authentication works.

What works: "getent passwd" display all users, including domain users; "getent group" also works correctly. "getent passwd USERNAME" does not work, i.e., it crashes with internal error.

/var/log/messages contains these lines:

Typeing command "ls -l" on a directory that contains files owned by domain users, trigger the same crash.

Connecting via ssh doesn't work because of ssh timeout while waiting for a reply. So this configuration made the system completely unaccessible.

Bye,

Hi, I am new to bugzilla. How do I assign this bug to samba-maintainers@suse.de?
Comment 2 Lars Müller 2009-11-09 05:11:56 UTC 
Reassign to samba-maintainers at SUSE.
Comment 3 Giuseppe Sacco 2009-11-09 06:37:01 UTC 
I just noticed an update for these packages. New version 3.4.3-3.1 does show the same behaviour.
Comment 4 Bo Yang 2009-12-03 01:25:18 UTC 
Created attachment 5049 [details]
for v3-4-test
Comment 5 Karolin Seeger 2010-03-08 04:19:38 UTC 
Any volunteer for a review?
Comment 6 Giuseppe Sacco 2010-03-08 04:47:19 UTC 
Has this fix included in 3.5.0-1.1 as available today at http://download.opensuse.org/repositories/network:/samba:/STABLE/SLE_10/x86_64
?
Comment 7 Lars Müller 2010-03-08 05:34:03 UTC 
From the package change log the fix is included.

  + BUG 6879: Fix crash in Winbind.

Please test and report back.
Comment 8 Lars Müller 2010-03-08 08:44:33 UTC 
With comment #7 I'm wrong.  The patch is not included with 3.5.0.

We're going to merge it into the TESTING repository of the openSUSE Build Service.  See http://en.openSUSE.org/Samba for the details.

Hmm, I do see it in the git log of v3-5-stable as well as in the release notes. So I think, this patch is included in 3.5.0.

It was applied and then reverted with 276461248. So this patch is not included in 3.5.0 indeed.
Comment 11 Lars Müller 2010-03-08 11:48:50 UTC 
Thanks Karolin.

@Giuseppe: Happy testing.
Comment 12 Jim McDonough 2010-08-18 14:44:47 UTC 
The fix is included.  The patch which "reverted" it simply moved where the check was done.
