pam_env: PAM module to set/unset environment variables

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

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 on.
