Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

When there is a revoked cert and a valid cert on the smartcards, login is successful.

When there is an expired cert and a valid cert on the smartcard, the login prompts for pin but authentication fails. This is how I tested with expired cert:

1. IPA issues a 1 day cert which is stored into the card.
2. I forward the system date to 2 days ahead.
3. Login using smartcard fails

the following are the messages in the log

Comment 5 Roshni 2016-09-07 19:09:21 UTC

Missed to mention that I disabled ocsp checking in sssd.conf

Comment 6 Sumit Bose 2016-09-16 16:36:59 UTC

The "VFY_VerifyData failed [-8182]." was caused by the invalid Samrtcard which we fixed recently, please re-test with the proper card.

Comment 7 Roshni 2016-09-18 17:06:00 UTC

Sumit,

I re-tested with a proper card and I was seeing the same issue when there was an expired cert on the card.
