NAME
       pam_env - PAM module to set/unset environment variables
SYNOPSIS
       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.
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 information is 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.
       user_envfile=filename
           Indicate an alternative .pam_environment file to override the
           default. This can be useful when different services need different
           environments. The filename is relative to the user home directory.
       user_readenv=0|1
           Turns on or off the reading of the user specific environment file.
           0 is off, 1 is on. By default this option is off as user supplied
           environment variables in the PAM environment could affect behavior
           of subsequent modules in the stack without the consent of the
           system administrator.
