Solution
Configure RHEL 9 to generate audit records for all account creations, modifications, disabling, and termination events that affect '/etc/passwd'.
Add or update the following file system rule to '/etc/audit/rules.d/audit.rules':
-w /etc/passwd -p wa -k identity
The audit daemon must be restarted for the changes to take effect.
