NAME

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

VERSION

       This document describes CGI::Application::Plugin::Authentication::Display version 0.20

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.
