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 2018-01-22 20:01:39 UTC 
This bug is created as a clone of upstream ticket:
https://pagure.io/SSSD/sssd/issue/3603

After investigating the issue #3602 (https://pagure.io/SSSD/sssd/issue/3602) seems that a similar issue may happen with certificates.

I've talked to @sbose and we agreed on opening this to investigate whether it's the case and then provide a proper fix for this in case a bug is also present.

Steps to reproduce will be added later on when someone starts working on this bug.
Comment 1 Jakub Hrozek 2018-01-22 20:02:52 UTC 
Rough steps to reproduce:

- add a certificate to an override of a subdomain user
- request the certificate with the dbus API
- remove the certificate from the override
- request the certificate again

If there are no certificates returned for a sub-domain user from the IPA
server to the client we should make sure they are not present in the
client's cache anymore and remove the whole attribute from the cached user
entry.
