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:
pam_faillock.so currently has no way of ignoring local users in /etc/passwd.
This causes problems where compliance organizations require faillock to be configured on all systems, and those systems are centrally managed with IdM or AD. Adding a local_users_only option to faillock would prevent issues with a centralized user account being locked out locally with faillock and centrally with IdM or AD. It would also make it easier and less error prone to configure system-auth and password-auth.

Version-Release number of selected component (if applicable):
All pam_faillock versions/releases

How reproducible:
Always

Steps to Reproduce:
1.
2.
3.

Actual results:
faillock configurations locks out both local and centralized users. local_users_only is not an option

Expected results:
faillock configurations locks out both local but not centralized users. local_users_only is an option

Additional info:

This issue was not selected to be included either in Red Hat Enterprise Linux 7.7 because it is seen either as low or moderate impact to a small amount of use-cases. The next release will be in Maintenance Support 1 Phase, which means that qualified Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released as they become available. We will now close this issue, but if you believe that it qualifies for the Maintenance Support 1 Phase, please re-open; otherwise we recommend moving the request to Red Hat Enterprise Linux 8 if applicable.

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
