Administration Reference

UserList

Purpose

Defines privileged administrators

Description

The UserList file lists the AFS usernames of the system administrators authorized to issue privileged bos, vos, and backup commands that affect the local server machine or the volumes housed on it. It must reside in the /usr/afs/etc directory on every server machine.

Although the UserList file is in ASCII format, do not use a text editor to alter it. Instead always use the appropriate commands from the bos command suite:

The bos adduser command to add a user to the file
The bos listusers command to display the contents of the file
The bos removeuser command to remove a user from the file

Although it is theoretically possible to list different administrators in the UserList files on different server machines, doing so can cause unanticipated authorization failures and is not recommended. In cells that run the United States edition of AFS and use the Update Server to distribute the contents of the /usr/afs/etc directory, it is customary to edit only the copy of the file stored on the system control machine. In cells that run the international version of AFS, edit the file on each server machine individually.
