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: cronie-1.5.2-6.el8
Doc Type: Bug Fix
Doc Text:
Cause: Upstream briefly changed the PAM settings for crond to use only password authentication for non-root users. Consequence: When other form of authentication were required by the system (i.e. smartcard authentication), crond failed to authorize the user even with right credentials. Fix: Upstream patch was backported that changed the PAM settings to use whatever authentication method were configured on the system. Result: A regular user can now be authenticated to utilize cron with any configured PAM authentication method.

Description Orion Poplawski 2021-09-17 22:27:07 UTC 
Description of problem:

It appears upstream briefly changed the crond pam configuration to use "password-auth" rather than "system-auth".  This breaks cron for users when smartcard auth is required.

PAM ERROR (Failure setting user credentials)

You (USER) are not allowed to access to (crontab) because of pam configuration.

Upstream reverted this here: https://github.com/cronie-crond/cronie/commit/978a00ea7ac92852c153ebb3b2152886730ca51c
which is in 1.5.3.
