pam_env
PAM_ENV(8) Linux-PAM Manual PAM_ENV(8)
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.
MODULE TYPES PROVIDED
The auth and session module types are provided.
RETURN VALUES
PAM_ABORT
Not all relevant data or options could be gotten.
PAM_BUF_ERR
Memory buffer error.
PAM_IGNORE
No pam_env.conf and environment file was found.
PAM_SUCCESS
Environment variables were set.
FILES
/etc/security/pam_env.conf
Default configuration file
/etc/environment
Default environment file
$HOME/.pam_environment
User specific environment file
