Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Comment 1 Martin Kosek 2015-01-21 21:01:59 UTC 
See details in
https://fedorahosted.org/freeipa/ticket/4844#comment:2
This is a regression in kinit.
Comment 2 Martin Kosek 2015-01-21 21:03:10 UTC 
Patch is ready, on review upstream:

https://github.com/krb5/krb5/pull/243
Comment 3 Martin Kosek 2015-01-21 21:07:37 UTC 
Reproduction/testing should be straightforward:

Instead of proper message:

$ kinit -C admin
kinit: Client 'admin' not found in Kerberos database while
getting initial credentials

user gets:

$ kinit -C admin
kinit: Looping detected inside krb5_get_in_tkt while getting initial
credentials
