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 Kashyap Chamarthy 2012-05-14 07:29:54 UTC 
Upstream ticket: https://fedorahosted.org/freeipa/ticket/2753


Version:
ipa-server-2.2.0-11.el6.x86_64 


A bit of context:
A couple of days ago, while testing expired certificates, I bumped the system date by 2
years (and reset it back by running '#ntpdate 66.187.233.4').


Today, while I debugging w/ shanks, a beakrun failure of ipa-ca-install', I was trying to
redo it manually,

and randomly, we tried to do a 'host-find' on Master, and this is what ensued:

==============================
[root@neptune ~]# klist

Martin suggested to try --delegate, and it seemed to return the entry just fine:
==============================
[root@neptune ~]# ipa --delegate host-find

Then, Sumit suggested to remove the ccache files httds use to access the directory server:

==============================
[root@neptune ~]# find /tmp -name 'krb5cc_48' | xargs rm
==============================

=> host-find now runs successfully:
==============================
[root@neptune ~]# ipa  host-find
--------------

Additional info:

>From Sumit when I mentioned the date changing and resetting it back:

"I still suspect that there is something wrong how apache handles the tickets. It should
replace the one it has with a new one because the new one might have different
authorization information."
