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.

Fixed In Version: krb5-1.19.1-15.el9
Doc Type: Known Issue
Doc Text:
.The DEFAULT:SHA1 sub-policy has to be set on RHEL 9 clients for PKINIT to work against AD The Active Directory (AD) Kerberos Distribution Center (KDC) supports different Cryptographic Message Syntax (CMS) signature algorithms than those supported by the MIT `krb5-pkinit` package that is used by RHEL 9 clients. AD KDC currently supports: * md5WithRSAEncryption * sha1WithRSAEncryption * ecdsa-with-sha1/256/384/512 MIT `krb5-pkinit` currently supports: * sha256WithRSAEncryption * sha512WithRSAEncryption Consequently, RHEL 9 clients fail when authenticating a user against an AD KDC by using Public Key Cryptography for initial authentication (PKINIT). To work around the problem, enable the deprecated `sha1WithRSAEncryption` algorithm on your RHEL 9 clients with the following command: ---- # update-crypto-polices --set DEFAULT:SHA1 ---- As a result, PKINIT authentication works between the RHEL 9 Kerberos clients and AD KDC.
