# This is a system configuration for allowing or denying certain users or
# groups to be able to do certain actions that involve system restricted
# actions such as halt, reboot, suspend, hibernate etc.
# This file is read in order from top to bottom - the first rule to MATCH
# will be used for a user or a group, and nothing after that is read.
# You must put all the ACTION definitons BEFORE user and group rule matches.
# Any action definitons after a rule match has been found will be ignored.
# This allows actions to be re-defined for different user groups, so matches
# so the command for an action can change for matches to the rules later on.
# Any user or group NOT matched by an allow or a deny will be ALLOWED to
# perform the action by default (system administrators should be aware of
# this and implement whatever policies they see fit). Generally speaking
# a user of a workstation, desktop or laptop is intended to have such abilities
# to perform these actions, thus the default of allow. For multi-user systems
# the system administrator is considered capable enough to restrict what they
# see they need to.
# A WARNING to admins: do NOT allow access for users to this system remotely
# UNLESS you fully trust them or you have locked down permissions to halt/reboot
# suspend etc. here first. You have been warned.
# action: halt /sbin/shutdown -h now
# action: reboot /sbin/shutdown -r now

# group: groupname deny: *
# group: * deny: *
# user: * allow: suspend
# user: billy allow: halt reboot
# group: staff deny: halt suspend hibernate
# etc.
# user and group name can use glob matches (* == all for example) like the
# shell. as can action names allowed or denied.
