SYNOPSIS
pam_env.so [debug] [conffile=conf-file] [envfile=env-file]

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.

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.
