NAME

       CGI::Application::Plugin::Authentication::Display - Generate bits of HTML needed for
       authentication

DESCRIPTION

       The purpose of this code is to keep display code away from the back-end of authentication
       management. It is an abstract base class and must be used in conjunction with derived
       classes. Those derived classes can be used in an number of ways:

       ·   The subclass CGI::Application::Plugin::Authentication::Display::Classic is provided to
           ensure backwards compatibility with the old code. It has the advantage of working out
           of the box but still retaining flexibility.

       ·   The subclass CGI::Application::Plugin::Authentication::Display::Basic is provided to
           ensure XHTML compliance and to leave styling to CSS style-sheets.

       ·   You can handle all the HTML side yourself in which case this code is not even loaded.

       ·   You can use derived classes in templates that have dot support, which keeps the
           display code close to the templates. This has other advantages. For example one can
           use the "enforce_protection" method to mark a template as being only viewable after
           authentication. A number of other methods can be called from the template that provide
           information about the authentication status.

METHODS

   new
       The constructor must be passed the CGI::Application object as the first non-object
       argument.  This allows derived modules to access the authentication information.

   login_box
       This method will return the HTML for a login box that can be embedded into another page.
       This is the same login box that is used in the default authen_login runmode that the
       plugin provides.

       This function is not implemented in this module. One must use a derived class with an
       appropriate implementation of this function.

   logout_form
       This returns the simple bit of HTML need to have a logout button. The form has
       '/?authen_logout=1' as the action but of course this can be changed in derived modules.

   enforce_protection
       This method is useful when the class is being used in templates to mark a certain template
       as for authenticated eyes only. So in HTML::Template::Plugin::Dot one might have

           <TMPL_VAR NAME="authen.enforce_protection">

       and one must set "authen" to one of these objects via the "HTML::Template::param" method.
       If authenticated it will resolve to a simple string, otherwise it will croak.

   login_title
       This returns the TITLE parameter from the LOGIN_FORM section of the config.

   is_authenticated
   username
   last_login
   last_access
   is_login_timeout
   login_attempts
       These methods all provide access to the cognate methods on the authentication object. They
       are provided as templates might find them expressive.
