Verify that all AlmaLinux OS 9 interactive users have a valid GID with the following command:
$ pwck -r /etc/passwd
If the system has any interactive users with a nonexistent primary group, this is a finding.

Configure the system so that all GIDs referenced in "/etc/passwd" are defined in "/etc/group".
