2 ## Note, to get this to work as it is currently typed you need
4 ## 1. to run an application as root
5 ## 2. add the following groups to the /etc/group file:
6 ## floppy, games, sound
9 # *** Please note that giving group membership on a session basis is
10 # *** NOT inherently secure. If a user can create an executable that
11 # *** is setgid a group that they are infrequently given membership
12 # *** of, they can basically obtain group membership any time they
13 # *** like. Example: games are allowed between the hours of 6pm and 6am
14 # *** user joe logs in at 7pm writes a small C-program toplay.c that
15 # *** invokes their favorite shell, compiles it and does
16 # *** "chgrp games toplay; chmod g+s toplay". They are basically able
17 # *** to play games any time... You have been warned. AGM
19 # this is an example configuration file for the pam_group module. Its
20 # syntax is based on that of the pam_time module and (at some point in
21 # the distant past was inspired by the 'shadow' package)
23 # the syntax of the lines is as follows:
25 # services;ttys;users;times;groups
27 # white space is ignored and lines maybe extended with '\\n' (escaped
28 # newlines). From reading these comments, it is clear that
29 # text following a '#' is ignored to the end of the line.
31 # the first four fields are described in the pam_time directory.
32 # The only difference for these is how the time field is interpretted:
33 # it is used to indicate "when" these groups are to be given to the user.
36 # The (comma or space separated) list of groups that the user
37 # inherits membership of. These groups are added if the previous
38 # fields are satisfied by the user's request
42 # Here is a simple example: running 'xsh' on tty* (any ttyXXX device),
43 # the user 'us' is given access to the floppy (through membership of
47 #xsh;tty*&!ttyp*;us;Al0000-2400;floppy
50 # another example: running 'xsh' on tty* (any ttyXXX device),
51 # the user 'sword' is given access to games (through membership of
52 # the floppy group) after work hours
55 #xsh; tty* ;sword;!Wk0900-1800;games, sound
56 #xsh; tty* ;*;Al0900-1800;floppy
59 # End of group.conf file
