RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. 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 Kaushik Banerjee 2011-07-22 09:48:41 UTC 
This bug is a split from bug 711416 to track the second issue.


RHEL6.2-20110512.n.0_nfs-Server-x86_64
Used by: Shanks

WARNING: Your password has expired.
You must change your password now and login again!
Changing password for user shanks.
Current Password: 
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.
Connection to localhost closed.


Actual results:
During the change password operation the ccache is not replaced by a new one if
the old one isn't active anymore.

[root@bumblebee ~]# ldb3search -H
/var/lib/sss/db/cache_lab.eng.pnq.redhat.com.ldb -b
name=shanks,cn=users,cn=lab.eng.pnq.redhat.com,cn=sysdb uidNumber gidNumber
ccacheFile
# record 1
dn: name=shanks,cn=users,cn=lab.eng.pnq.redhat.com,cn=sysdb
ccacheFile: FILE:/tmp/krb5cc_1866400007_wPJrHJ
uidNumber: 1866400008
gidNumber: 1866400008


[root@bumblebee ~]# ls -l /tmp/krb5cc_1866400007_wPJrHJ 
-rw-------. 1 shanks shanks 604 Jun  7 07:41 /tmp/krb5cc_1866400007_wPJrHJ
[root@bumblebee ~]# 


Expected results:
We should delete ccacheFile attribute from the cache if we detect we don't need
to hold one anymore before we continue authentication.

Comment 1 Kaushik Banerjee 2011-07-22 09:49:56 UTC 
The bug is for tracking the following issue:

The uid of a user changed, because the user was deleted and added
afterwards with a new uid. Since sssd reuses the same cached object the stored
ccache file now belongs to a different user ("Cache file
[/tmp/krb5cc_1866400007_wPJrHJ] exists, but is owned by [1866400007] instead of [1866400008]."). This is tracked upstream in ticket https://fedorahosted.org/sssd/ticket/884 .
Comment 6 Martin Kosek 2015-04-24 11:21:32 UTC 
Thank you taking your time and submitting this request for Red Hat Enterprise Linux. Unfortunately, this bug was not given a priority and was deferred both in the upstream project and in Red Hat Enterprise Linux.

Given that we are unable to fulfill this request in following Red Hat Enterprise Linux releases, I am closing the Bugzilla as DEFERRED. To request that Red Hat re-considers the decision, please re-open the Bugzilla via appropriate support channels and provide additional business and/or technical details about its importance to you.

Note that you can still track this request or even contribute patches in the referred upstream Trac ticket.
Note You need to log in before you can comment on or make changes to this bug.
