=head1 NAME

Lemonldap::NG::Portal - The authentication portal part of Lemonldap::NG Web-SSO
system.

=head1 SYNOPSIS

Use any of Plack launcher. Example:

  #!/usr/bin/env plackup
  
  use Lemonldap::NG::Portal;
  
  # This must be the last instruction! See PSGI for more
  Lemonldap::NG::Portal->run($opts);

=head1 DESCRIPTION

Lemonldap::NG is a modular Web-SSO based on Apache::Session modules. It
provides an easy way to build a secured area to protect applications with
very few changes.

Lemonldap::NG manages both authentication and authorization. Furthermore
it provides headers for accounting. So you can have a full AAA protection
for your web space as described below.

Lemonldap::NG::Portal provides portal components. See
L<http://lemonldap-ng.org> for more.

=head1 KINEMATICS

The portal object is based on L<Lemonldap::NG::Handler::Try>: underlying
handler tries to authenticate user and follows initialized auth / unauth
routes.

=head2 Initialization

Initialization process subscribes portal to handler configuration reload and
requests handler initialization (L<Lemonldap::NG::Portal::Main::Init>).
So configuration is read by handler at each reload.

During configuration reload, each enabled components are loaded as plugins:

=over

=item authentication module

=item userDB module

=item other enabled plugins (issuers,...)

=back

init() is called for each plugin. If a plugin initialization fails (init()
returns 0), the portal responds a 500 status code for each request.

See L<Lemonldap::NG::Portal::Main::Plugin> to see how to write modules.

=head2 Main route

The "/" route is declared in L<Lemonldap::NG::Portal::Main::Init>. It points to
different methods in L<Lemonldap::NG::Portal::Main::Run>. Theses methods select
methods to call in the process and call do().

do() stores methods to call in $req->steps and launches
Lemonldap::NG::Portal::Main::Process::process(). This method removes each method
stored in $req->steps and launches it. If the result is PE_OK, process()
continues, else it returns the error code.

If it is an Ajax request, do() responds in JSON format else it manages
redirection if any. Else it calls
Lemonldap::NG::Portal::Main::Display::display() to load template and arguments,
and launches Lemonldap::NG::Common::PSGI::sendHtml() using them.

=head1 DEVELOPER INSTRUCTIONS

Portal main object is defined in Lemonldap::NG::Portal::Main::* classes. Other
components are plugins. Plugins do not have to store any hash key in main object.

Main and plugin keys must be set during initialization process. They must
be read-only during requests receiving.

The L<Lemonldap::NG::Portal::Main::Request> request has fixed keys. A plugin
that wants to store a temporary key must store it in C<$req-E<gt>data> or use
defined keys, but it must never create a root key. Plugin keys may have
explicit names to avoid conflicts.

Whole configuration is always available. It is stored in $self->conf. It must
not be modified by any components even during initialization process or
receiving request (during initialization, copy the value in the plugin
namespace instead).

All plugins can access to portal methods using $self->p which points to
portal main object. Some main methods are mapped to the plugin namespace:

=over

=item logger() accessor to log

=item userLogger() accessor to log user actions

=item error() accessor (use it to store error during initialization)
