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.
.Kerberos ticket policy now supports authentication indicators
Authentication indicators are attached to Kerberos tickets based on which pre-authentication mechanism has been used to acquire the ticket:
* `otp` for two-factor authentication (password + OTP)
* `radius` for RADIUS authentication
* `pkinit` for PKINIT, smart card or certificate authentication
* `hardened` for hardened passwords (SPAKE or FAST)
The Kerberos Distribution Center (KDC) can enforce policies such as service access control, maximum ticket lifetime, and maximum renewable age, on the service ticket requests which are based on the authentication indicators.
With this enhancement, administrators can achieve finer control over service ticket issuance by requiring specific authentication indicators from a user's tickets.

Complete Authentication Indicator Kerberos ticket policy support by providing IPA CLI options.
For the authentication indicators 'otp', 'radius', 'pkinit', and 'hardened', allow specifying maximum ticket life and maximum renewable age in Kerberos ticket policy.
The policy extensions are now loaded when a Kerberos principal data is requested by the KDC and evaluated in AS_REQ KDC policy check. If one of the authentication indicators mentioned above is present in the AS_REQ, corresponding policy is applied to the ticket.
