pam_exec

PAM_EXEC(8)							 Linux-PAM Manual						       PAM_EXEC(8)

NAME

       pam_exec - PAM module which calls an external command

SYNOPSIS

       pam_exec.so [debug] [expose_authtok] [seteuid] [quiet] [log=file] 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.

OPTIONS

       debug
	   Print debug information.

       expose_authtok
	   During authentication the calling command can read the password from stdin(3).

       log=file
	   The output of the command is appended to file

       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.

MODULE TYPES PROVIDED

       All module types (auth, account, password and session) are provided.

RETURN VALUES

       PAM_SUCCESS
	   The external command was run successfully.

       PAM_SERVICE_ERR
	   No argument or a wrong number of arguments were given.

       PAM_SYSTEM_ERR
	   A system error occurred or the command to execute failed.

       PAM_IGNORE

	   pam_setcred was called, which does not execute the command.

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.
