If a user can create an executable that +# *** is setgid a group that they are infrequently given membership +# *** of, they can basically obtain group membership any time they +# *** like. Example: games are allowed between the hours of 6pm and 6am +# *** user joe logs in at 7pm writes a small C-program toplay.c that +# *** invokes their favorite shell, compiles it and does +# *** "chgrp play toplay; chmod g+s toplay".

AGM +# + +# +# The syntax of the lines is as follows: +# +# services;ttys;users;times;groups +# +# white space is ignored and lines maybe extended with '\\n' (escaped +# newlines). From reading these comments, it is clear that +# text following a '#' is ignored to the end of the line. +# +# the combination of individual users/terminals etc is a logic list +# namely individual tokens that are optionally prefixed with '!' (logical +# not) and separated with '&' (logical and) and '|' (logical or). +# +# services +# is a logic list of PAM service names that the rule applies to. +# +# ttys +# is a logic list of terminal names that this rule applies to. +# +# users +# is a logic list of users or a netgroup of users to whom this +# rule applies. +# +# NB. For these items the simple wildcard '*' may be used only once. +# With netgroups no wildcards or logic operators are allowed. +# +# times +# It is used to indicate "when" these groups are to be given to the +# user. The format here is a logic list of day/time-range +# entries the days are specified by a sequence of two character +# entries, MoTuSa for example is Monday Tuesday and Saturday. Note +# that repeated days are unset MoMo = no day, and MoWk = all weekdays +# bar Monday. The two character combinations accepted are +# +# Mo Tu We Th Fr Sa Su Wk Wd Al +# +# the last two being week-end days and all 7 days of the week +# respectively. As a final example, AlFr means all days except Friday. +# +# Each day/time-range can be prefixed with a '!' to indicate "anything +# but" +# +# The time-range part is two 24-hour times HHMM separated by a hyphen +# indicating the start and finish time (if the finish time is smaller +# than the start time it is deemed to apply on the following day). +# +# groups +# The (comma or space separated) list of groups that the user +# inherits membership of.
