SYNOPSIS
- pam_env.so [debug] [conffile=conf-file] [envfile=env-file] [readenv=0|1] [user_envfile=env-file] [user_readenv=0|1]
DESCRIPTION
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 separate 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.
Since setting of PAM environment variables can have side effects to other modules, this module should be the last one on the stack.
