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.

Settting to post, we can't reproduce with most recent upstream build which was used for rebase.

Comment 8 Sudhir Menon 2016-07-05 12:22:08 UTC 
Able to reproduce the below issue with ipa-server-4.4.0-1.el7.x86_64 on 
Red Hat Enterprise Linux Server release 7.3 Beta (Maipo) during uninstall.

Failed to remove Kerberos service principals: Command '/usr/sbin/ipa-rmkeytab -k /etc/krb5.keytab -r TESTRELM.TEST' returned non-zero exit status 5
Comment 9 Rob Crittenden 2016-07-05 13:00:12 UTC 
Exit code 5 means Principal name or realm not found in keytab.

It would be helpful to see the contents of the keytab prior to and after running uninstall.
Comment 10 Sudhir Menon 2016-07-05 13:12:42 UTC 
Rob, this is what is seen on the test system

Comment 18 Petr Vobornik 2016-07-07 12:16:58 UTC 
This bz has incorrect state it should be on QA or assigned(provided it is not fixed).

From the comments it seems that it can be reproduce only under certain conditions which are not known yet.
Comment 19 Petr Vobornik 2016-07-08 13:29:17 UTC 
moving to assigned, reproduction scenario of #3 is known:
"""
it happens because the server uninstaller first restores all the files (including /etc/krb5.keytab), then call client-uninstall which tries to run ipa-rmkeytab
"""
