     authentication and session management.

     failure if the user is attempting to authenticate as superuser, and the
     process is attached to an insecure TTY.  In all other cases, the module

     A TTY is considered secure if it is listed in /etc/ttys and has the
     TTY_SECURE flag set.

     The following options may be passed to the authentication module:
