Check Text (C-75882r1092206_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.

Edit the file "/etc/passwd" and provide each interactive user account that has a duplicate UID with a unique UID.
