Check Text (C-281172r1166468_chk)

Verify RHEL 10 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-85638r1166467_fix)

Configure RHEL 10 to not allow duplicate UIDs to exist for interactive users. Edit the file "/etc/passwd", and provide each interactive user account that has a duplicate UID with a unique UID.
