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.

Doc Text:
.MIT Kerberos does not support ECC certificates for PKINIT MIT Kerberos does not implement the RFC5349 request for comments document, which describes the design of elliptic-curve cryptography (ECC) support in Public Key Cryptography for initial authentication (PKINIT). Consequently, the MIT `krb5-pkinit` package, used by RHEL, does not support ECC certificates. For more information, see link:https://www.rfc-editor.org/rfc/rfc5349.html[Elliptic Curve Cryptography (ECC) Support for Public Key Cryptography for Initial Authentication in Kerberos (PKINIT)].

Description Julien Rische 2022-07-11 15:24:09 UTC
MS-PKCA v20211006 (section 2.2)[1] defines the following supported algorithms for PKINIT CMS signature:

  * md5WithRSAEncryption (since Windows Server 2003)
  * sha1WithRSAEncryption (newer than Windows Server 2003)
  * ecdsa-with-sha1/256/384/512 (newer than Windows Server 2008)

Out of this list, ECDSA signatures are the only ones that are still allowed to verify on RHEL9 (SHA-1 and MD5 signatures verification is disallowed by default). We should implement RFC5349[2] in MIT krb5 in order to support PKINIT pre-authentication against Active Directory.
