Check Text (C-271832r1092208_chk)
Verify that OL 9 contains no duplicate UIDs for interactive users with the following command:
$ sudo awk -F ":" 'list[$3]++{print $1, $3}' /etc/passwd
If output is produced and the accounts listed are interactive user accounts, this is a finding.
Fix Text (F-75789r1092207_fix)
Edit the file "/etc/passwd" and provide each interactive user account that has a duplicate UID with a unique UID.
