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 Jakub Hrozek 2015-03-17 10:16:04 UTC
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/2596

FreeIPA ticket https://fedorahosted.org/freeipa/ticket/4238 asks for ability to map CAC identity certificates to users in IdM. When this is implemented, we will need a way to make a lookup using sssd based on the certificate or certificate attribute(s).

One use case is: Apache is configured to do SSL client authentication based on mod_ssl (or mod_nss). When the authentication passes, SSL_* variables are set, including SSL_CLIENT_S_DN, SSL_CLIENT_S_DN_*, or SSL_CLIENT_CERT. If the information about the certificate or the whole PEM-encoded certificate is stored in IdM database, it should be possible to amend for example mod_lookup_identity to query sssd, and lookup the username based on SSL_CLIENT_CERT. We are looking for something like org.freedesktop.sssd.infopipe.!LookupUserUsingCert but the name of the method (or how exactly this should be exposed) is to be determined.

Additional fix for #2742 is coming up, moving back to ASSIGNED.

Comment 9 Scott Poore 2015-09-21 19:45:50 UTC
How can I test this?  

Would the same test as for bug #1241089 cover this as well?  Sounds like that bug specifically asks for an update to mod_lookup_identity to use the fix from this for org.freedesktop.sssd.infopipe.Users.FindByCertificate.

If I can't use the verification for that bug to verify this, please list steps to test.

Thanks,
Scott

Please see 'How to Test' section of https://fedorahosted.org/sssd/wiki/DesignDocs/LookupUsersByCertificate for details.
