pam_env: PAM module to set/unset environment variables
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]
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.
- Indicate an alternative pam_env.conf style configuration file to override the default. This can be useful when different services need different environments.
- A lot of debug information is printed with syslog(3).
- 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.
- Turns on or off the reading of the file specified by envfile (0 is off, 1 is on). By default this option is on.
- 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.
- Turns on or off the reading of the user specific environment file. 0 is off, 1 is on. By default this option is off.
