NAME¶pam_env - PAM module to set/unset environment variables
pam_env.so [debug] [conffile=conf-file] [envfile=env-file] [readenv=0|1] [user_envfile=env-file] [user_readenv= 0|1]
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 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.
