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 of problem:

The presence of a [domain_realm] profile mapping in /etc/krb5.conf prevents DNS-based kerberos referrals from working. As IdM starts supporting realm trust, it probably makes sense to not populate [domain_realm] by default, pushing clients to perform DNS realm lookups (_kerberos TXT record for realm).

Upstream ticket:
https://pagure.io/freeipa/issue/7631

Based on our discussions with Robbie and others, I published an article explaining a situation with Kerberos service translation and what we need to update in MIT Kerberos to allow administrators to control name resolution order on the clients: https://vda.li/en/posts/2019/03/24/Kerberos-host-to-realm-translation/
