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]
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.
conffile=/path/to/pam_env.confIndicate an alternative pam_env.conf style configuration file to override the default. This can be useful when different services need different environments.
debugA lot of debug information is printed with syslog(3).
envfile=/path/to/environmentIndicate an alternative environment file to override the default. This can be useful when different services need different environments.
readenv=0|1Turns 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=filenameIndicate 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|1Turns on or off the reading of the user specific environment file. 0 is off, 1 is on. By default this option is on.
