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.
