- # This is the configuration file for pam_env, a PAM module to load in
- # a configurable list of environment variables for a

- # The original idea for this came from Andrew G. Morgan ...

- # Mmm. Perhaps you might like to write a pam_env module that reads a
- # default environment from a file? I can see that as REALLY
- # useful... Note it would be an "auth" module that returns PAM_IGNORE
- # for the auth part and sets the environment returning PAM_SUCCESS in
- # the setcred function...

- # What I wanted was the REMOTEHOST variable set, purely for selfish
- # reasons, and AGM didn't want it added to the SimpleApps login
- # program (which is where I added the patch). So, my first concern is
- # that variable, from there there are numerous others that might/would
- # be useful to be set: NNTPSERVER, LESS, PATH, PAGER, MANPAGER .....
- #
- # Of course, these are a different kind of variable than REMOTEHOST in
- # that they are things that are likely to be configured by
- # administrators rather than set by logging in, how to treat them both
- # in the same config file?
- #
- # Here is my idea:
- #
- # Each line starts with the variable name, there are then two possible
- # options for each variable DEFAULT and OVERRIDE.
- # DEFAULT allows and administrator to set the value of the
- # variable to some default value, if none is supplied then the empty
- # string is assumed. The OVERRIDE option tells pam_env that it should
- # enter in its value (overriding the default value) if there is one
- # to use. OVERRIDE is not used, "" is assumed and no override will be
- # done.
- #
- # VARIABLE [DEFAULT=[value]] [OVERRIDE=[value]]
- #
- # (Possibly non-existent) environment variables may be used in values
- # using the ${string} syntax and (possibly non-existent) PAM_ITEMs may
- # be used in values using the @{string} syntax. Both the $ and @
- # characters can be backslash escaped to be used as literal values
- # values can be delimited with "", escaped " not supported.
- # Note that many environment variables that you would like to use
- # may not be set by the time the module is called.
- # For example, HOME is used below several times, but
- # many PAM applications don't make it available by the time you need it.
- #
- #
- # First, some special variables
- #
- # Set the REMOTEHOST variable for any hosts that are remote, default
- # to "localhost" rather than not being set at all
- #REMOTEHOST DEFAULT=localhost OVERRIDE=@{PAM_RHOST}
- #
- # Set the DISPLAY variable if it seems reasonable
- #DISPLAY DEFAULT=${REMOTEHOST}:0.0 OVERRIDE=${DISPLAY}
- #
- #
- # Now some simple variables
- #
- #PAGER DEFAULT=less
- #MANPAGER DEFAULT=less
- #LESS DEFAULT="M q e h15 z23 b80"
- #NNTPSERVER DEFAULT=localhost
- #PATH DEFAULT=${HOME}/bin:/usr/local/bin:/bin\
- #:/usr/bin:/usr/local/bin/X11:/usr/bin/X11
- #
- # silly examples of escaped variables, just to show how they work.

- #DOLLAR DEFAULT=\$
- #DOLLARDOLLAR DEFAULT= OVERRIDE=\$${DOLLAR}
- #DOLLARPLUS DEFAULT=\${REMOTEHOST}${REMOTEHOST}
- #ATSIGN DEFAULT="" OVERRIDE=\@
