pam_exec -- PAM module which calls an external command

   --------------------------------------------------------------------------

DESCRIPTION

   pam_exec is a PAM module that can be used to run an external command.

   The child's environment is set to the current PAM environment list, as
   returned by pam_getenvlist(3) In addition, the following PAM items are
   exported as environment variables: PAM_RHOST, PAM_RUSER, PAM_SERVICE,
   PAM_TTY, PAM_USER and PAM_TYPE, which contains one of the module types:
   account, auth, password, open_session and close_session.

   Commands called by pam_exec need to be aware of that the user can have
   controll over the environment.

OPTIONS

   debug

           Print debug information.

   expose_authtok

           During authentication the calling command can read the password
           from stdin(3). Only first PAM_MAX_RESP_SIZE bytes of a password
           are provided to the command.

   log=file

           The output of the command is appended to file

   type=type

           Only run the command if the module type matches the given type.

   stdout

           Per default the output of the executed command is written to
           /dev/null. With this option, the stdout output of the executed
           command is redirected to the calling application. It's in the
           responsibility of this application what happens with the output.
           The log option is ignored.

   quiet

           Per default pam_exec.so will echo the exit status of the external
           command if it fails. Specifying this option will suppress the
           message.

   seteuid

           Per default pam_exec.so will execute the external command with the
           real user ID of the calling process. Specifying this option means
           the command is run with the effective user ID.

EXAMPLES

   Add the following line to /etc/pam.d/passwd to rebuild the NIS database
   after each local password change:

         password optional pam_exec.so seteuid /usr/bin/make -C /var/yp


   This will execute the command

 make -C /var/yp

   with effective user ID.
