pam_env — PAM module to set/unset environment variables
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
DESCRIPTION
The pam_env PAM module allows the (un)setting of environment variables.
Supported is the use of previously set environment variables as well as
PAM_ITEMs such as PAM_RHOST.
By default rules for (un)setting of variables is taken from the config file /
etc/security/pam_env.conf if no other file is specified.
This module can also parse a file with simple KEY=VAL pairs on seperate lines
(/etc/environment by default). You can change the default file to parse, with
the envfile flag and turn it on or off by setting the readenv flag to 1 or 0
respectively.
OPTIONS
conffile=/path/to/pam_env.conf
Indicate an alternative pam_env.conf style configuration file to override
the default. This can be useful when different services need different
environments.
debug
A lot of debug informations are printed with syslog(3).
envfile=/path/to/environment
Indicate an alternative environment file to override the default. This can
be useful when different services need different environments.
readenv=0|1
Turns on or off the reading of the file specified by envfile (0 is off, 1
is on). By default this option is on.
EXAMPLES
These are some example lines which might be specified in /etc/security/
pam_env.conf.
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=\@
