Ensure no duplicate UIDs exist

An XCCDF Rule

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.

warning alert: Warning

Due to the risk of removing user accounts or changing user's UIDS, automated remediation is not available for this configuration check.

Rationale

Users must be assigned unique UIDs for accountability and to ensure appropriate access protections.
