Имя (Name)

pam_env - PAM module to set/unset environment variables

---

Синопсис (Synopsis)

pam_env.so [debug] [conffile=conf-file] [envfile=env-file] [readenv=0|1] [user_envfile=env-file] [user_readenv=0|1]

---

Описание (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 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.

Параметры (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. 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.
