Check Text (C-274160r1120663_chk)
Verify Amazon Linux 2023 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-78156r1120467_fix)
Configure Amazon Linux 2023 to contain no duplicate UIDs for interactive users.
Edit the file "/etc/passwd" and provide each interactive user account that has a duplicate UID with a unique UID.
