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 of problem:
Security Guidance advises people to not login via root. This is enforced in several places based on the security guides. However, it  looks like if someone/everyone gets locked out, it possibly requires a root login because the is the only account exempt from the lockout policy.

Most admins are members of the wheel group. Security Guidance typically asks admins to fix su or sudo to only allow wheel group members the ability to become root. I am wondering if the lockout exemptions for root should also be optionally extended to wheel group members so that we have a recovery method consistent with security guidance.

So what PAM modules are we talking here about?

pam_faillock is clearly one. Is there anything else?

pam_faillock is the main one. I presume the pam_tally* modules are being deprecated at some future point.
