Check Text (C-282490r1200450_chk)
Verify all TOSS 5 interactive users have a valid GID using the following command:
$ sudo pwck -qr
If the system has any interactive users with duplicate GIDs, this is a finding.
Fix Text (F-86956r1200449_fix)
Configure the system so all GIDs referenced in "/etc/passwd" are defined in "/etc/group".
Edit the file "/etc/passwd" and ensure every user's GID is a valid GID.
