NAME <\/a> <\/h2>\n

pam_env \u2212 PAM module to set\/unset environment variables<\/p>\n

SYNOPSIS <\/a> <\/h2>\n\n\n
<\/td>\n\n

pam_env.so<\/b> [debug] [conffile=conf\u2212file<\/i>] [envfile=env\u2212file<\/i>] [readenv=0|1<\/i>] [user_envfile=env\u2212file<\/i>] [user_readenv=0|1<\/i>]<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

DESCRIPTION <\/a> <\/h2>\n

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_ITEM<\/i>s such as PAM_RHOST<\/i>.<\/p>\n

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<\/i> option.<\/p>\n

Second a file (\/etc\/environment by default) with simple KEY=VAL<\/i> pairs on separate lines will be read. With the envfile<\/i> option an alternate file can be specified. And with the readenv<\/i> option this can be completly disabled.<\/p>\n

Third it will read a user configuration file ($HOME\/.pam_environment by default). The default file file can be changed with the user_envfile<\/i> option and it can be turned on and off with the user_readenv<\/i> option.<\/p>\n

Since setting of PAM environment variables can have side effects to other modules, this module should be the last one on the stack.<\/p>\n

OPTIONS <\/a> <\/h2>\n

conffile=<\/b>\/path\/to\/pam_env.conf<\/i><\/p>\n

Indicate an alternative pam_env.conf style configuration file to override the default. This can be useful when different services need different environments.<\/p>\n

debug<\/b><\/p>\n

A lot of debug information is printed with syslog<\/b>(3).<\/p>\n

envfile=<\/b>\/path\/to\/environment<\/i><\/p>\n

Indicate an alternative environment file to override the default. The syntax are simple KEY=VAL<\/i> pairs on separate lines. The export<\/i> instruction can be specified for bash compatibility, but will be ignored. This can be useful when different services need different environments.<\/p>\n

readenv=<\/b>0|1<\/i><\/p>\n

Turns on or off the reading of the file specified by envfile (0 is off, 1 is on). By default this option is on.<\/p>\n

user_envfile=<\/b>filename<\/i><\/p>\n

Indicate an alternative .pam_environment file to override the default.The syntax is the same as for \/etc\/environment<\/i>. The filename is relative to the user home directory. This can be useful when different services need different environments.<\/p>\n

user_readenv=<\/b>0|1<\/i><\/p>\n

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.<\/p>\n

MODULE TYPES PROVIDED <\/a> <\/h2>\n

The auth<\/b> and session<\/b> module types are provided.<\/p>\n

RETURN VALUES <\/a> <\/h2>\n

PAM_ABORT<\/p>\n

Not all relevant data or options could be gotten.<\/p>\n

PAM_BUF_ERR<\/p>\n

Memory buffer error.<\/p>\n

PAM_IGNORE<\/p>\n

No pam_env.conf and environment file was found.<\/p>\n

PAM_SUCCESS<\/p>\n

Environment variables were set.<\/p>\n

FILES <\/a> <\/h2>\n

\/etc\/security\/pam_env.conf<\/p>\n

Default configuration file<\/p>\n

\/etc\/environment<\/p>\n

Default environment file<\/p>\n

$HOME\/.pam_environment<\/p>\n

User specific environment file<\/p>\n
