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 completely disabled. + +Third it will read a user configuration file ($HOME/.pam_environment by +default). The default 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. + +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/security/pam_env.conf. 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.
