Check for Duplicate User Names

MittelStufe 1Automatisiertsolaris

Beschreibung

Although the useradd program will not let you create a duplicate user name, it is possible for an administrator to manually modify passwd(4) and change the user name. If a user is assigned a duplicate user name, it will create and have access to files with the first UID for that username in passwd(4). Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
