USERS(6)							   Games Manual 							  USERS(6)

NAME

       users - file server user list format

DESCRIPTION

       The  permanent  file  servers each maintain a private list of users and groups, in /adm/users by convention.  Each line in the file has the
       format

	      num:name:leader:members

       where num is a decimal integer, name and leader are printable strings excluding the characters and and members is a comma-separated list of
       such  strings.	Such a line defines a user and a group with the given name; the group has a group leader given by leader and group members
       given by the user names in members.  The leader field may be empty, in which case any group member is a group leader.   The  members  field
       may be empty.

       Lines beginning with are ignored.

       The  num in a line is a number used internally by a file server; there should be no duplicate nums in the file.	A negative num is special:
       a user with a negative num cannot attach to the file server.  The file /adm/users itself is owned by user adm, having a negative  num,  and
       write protected to others, so it can only be changed via console commands.

NAME

       gshadow - shadowed group file

DESCRIPTION

       /etc/gshadow contains the shadowed information for group accounts.

       This file must not be readable by regular users if password security is to be maintained.

       Each line of this file contains the following colon-separated fields:

       group name
           It must be a valid group name, which exist on the system.

       encrypted password
           Refer to crypt(3) for details on how this string is interpreted.

           If the password field contains some string that is not a valid result of crypt(3), for instance ! or *, users will not be able to use a
           unix password to access the group (but group members do not need the password).

           The password is used when a user who is not a member of the group wants to gain the permissions of this group (see newgrp(1)).

           This field may be empty, in which case only the group members can gain the group permissions.

           A password field which starts with an exclamation mark means that the password is locked. The remaining characters on the line
           represent the password field before the password was locked.

           This password supersedes any password specified in /etc/group.

       administrators
           It must be a comma-separated list of user names.

           Administrators can change the password or the members of the group.

           Administrators also have the same permissions as the members (see below).

       members
           It must be a comma-separated list of user names.

           Members can access the group without being prompted for a password.

           You should use the same list of users as in /etc/group.
