Ensure no duplicate UIDs exist

SrednjaNivo 1Automatskafreebsd

Opis

Although the adduser or pw program will not let you create a duplicate User ID (UID), an administrator can manually edit the /etc/passwd file and change the UID field. Users must be assigned unique UIDs for accountability and to ensure appropriate access protections. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
