Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Rik Theys 2016-05-02 08:07:07 UTC

Hi,

This bug also affects RHEL6 with samba4 packages since they were upgraded to 4.2.10 (badlock bug).

Upstream has a patch for this.

Regards,

Rik

+++ This bug was initially created as a clone of Bug #1331763 +++

Description of problem:

/var/log/messages fills with  below error messges

winbindd[xxxx]:   gss_init_sec_context failed with [Unspecified GSS failure.  Minor code may provide more information: Ticket expired]

After winbind packages upgraded to -4.2.11-2, in a RHGS 3.1 node that is integrated with Active Directory . 


Version-Release number of selected component (if applicable):

Red Hat Gluster Storage 3.1
samba-winbind-4.2.11-2.el6rhs.x86_64

How reproducible:

Always. 

Steps to Reproduce:
1. Install RHGS 3.1 with samba-windbind-4.2.11-2
2. Integrate with Active Directory 
3. Check the /var/log/messages. 

Actual results:

winbindd[xxxx]:   gss_init_sec_context failed with [Unspecified GSS failure.  Minor code may provide more information: Ticket expired]

Above messages in the /var/log/messages , since windbind not know  when to get a new krb5 ticket since a regression in the mentioned package. 


Expected results:

windbind handle session expiry properly and avoid the warning message.
