AD login stopped working after yesterday's samba update

Hi,

I have an OpenSUSE 13.2 laptop joined to an AD. This morning I logged in while offline since the local password was cached. I connected to the VPN and started working. After some time I got some strange occurences, e.g. sudo complaining that it knew nothing about my UID. I though this was an upgrade leftover issue so I decided to reboot. After rebooting I can no longer login with my domain user ( I am not connected to the AD ).

/var/log/messages says:

2015-02-27T09:56:00.777049+02:00 rmuntean-w7 kdm: :0[1854]: gkr-pam: error looking up user information

wbinfo -u returns nothing

The only thing that has changed is yesterday’s samba update, but that really does not sound related:

$ rpm -q --changelog samba | head

- Update to 4.1.17.
  + Ensure we don't call talloc_free on an uninitialized pointer;
    CVE-2015-0240; (bso#11077); (bnc#917376).

* Thu Jan 22 2015 lmuelle@suse.com
- Update to 4.1.16.

Any ideas on how I can debug this further?

Thanks,

Robert

After tinkering a bit this started working again … What was maybe relevant:

net ads testjoin ( was successful )
kinit $DOMAIN_USER ( was also successful )

At that point I tried ssh DOMAIN\user@localhost which worked.

Still no idea why it broken, but at least it’s back…
