PAM_ENV(8) Linux-PAM Manual PAM_ENV(8)
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 are taken from the
config file /etc/security/pam_env.conf. An alternate file can be
specified with the conffile option.
Second a file (/etc/environment by default) with simple KEY=VAL pairs
on separate lines will be read. With the envfile option an alternate
file can be specified. And with the readenv option this can be
completly disabled.
Third it will read a user configuration file ($HOME/.pam_environment
by default). The default file file can be changed with the
user_envfile option and it can be turned on and off with the
user_readenv option.
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.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.
The syntax are simple KEY=VAL pairs on separate lines. The export
instruction can be specified for bash compatibility, but will be
ignored. 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.The syntax is the same as for /etc/environment. The
filename is relative to the user home directory. This can be
useful when different services need different environments.
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.
The auth and session module types are provided.
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.
/etc/security/pam_env.conf
Default configuration file
/etc/environment
Default environment file
$HOME/.pam_environment
User specific environment file
pam_env.conf(5), pam.d(5), pam(8), environ(7).
