The login page consists of two separate parts: the login form page, and a login message page.
The login form page contains a form prompting for the guest's username and password. The title, header and footer
of this page can be customized. If the Provide a custom login form option is selected, then the form must also be
provided in either the Header HTML or Footer HTML sections.
The login message page is displayed after the login form has been submitted, while the guest is being redirected to
the NAS for login. The title and message displayed on this page can be customized.
