Ensure no duplicate UIDs exist

보통레벨 1자동cos

설명

Although the useradd program will not let you create a duplicate User ID (UID), it is possible for an administrator to 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.
