NAME

       Lemonldap:NG::Portal::Auth - Writing authentication modules for LemonLDAP::NG.

SYNOPSIS

         package Lemonldap::NG::Portal::Auth::My;

         use strict;
         use Mouse;
         # Add constants used by this module
         use Lemonldap::NG::Portal::Main::Constants qw(PE_OK);

         our $VERSION = '0.1';

         # Directive provides by Mouse
         extends 'Lemonldap::NG::Portal::Main::Auth';

         sub init {
             ...
         }

         sub extractFormInfo {
             my ( $self, $req ) = @_;
             ...
         }

         sub authenticate {
             my ( $self, $req ) = @_;
             ...
         }

         sub setAuthSessionInfo {
             my ( $self, $req ) = @_;
             ...
         }

         sub authLogout {
             my ( $self, $req ) = @_;
             ...
         }

         sub getDisplayType {
             return ...;
         }

         1;

DESCRIPTION

       Lemonldap::NG::Portal::Main::Auth must be used to build Lemonldap::NG authentication
       modules. Authentication modules are independent objects that are instantiated by
       Lemonldap::NG portal. They must provide methods described below.

METHODS

   Accessors and methods provided by Lemonldap::NG::Portal::Main::Auth
       p: portal object
       conf: configuration hash (as reference)
       logger alias for p->logger accessor
       userLogger alias for p->userLogger accessor
       error: alias for p->error method
       authnLevel: Lemonldap::NG authentication level

       "Routes" management

       Like each module that inherits from Lemonldap::NG::Portal::Plugin,
       Lemonldap::NG::Portal::Main::Auth provides URI path functions:

       addAuthRoute: wrapper to Lemonldap::NG::Handler::PSGI::Try addAuthRoute() method
       addUnauthRoute: wrapper to Lemonldap::NG::Handler::PSGI::Try addUnauthRoute() method

       Example:

         sub init {
             ...
             $self->addAuthRoute( saml => { proxy => "proxySub" }, [ 'GET', 'POST' ] );
             ...
         }
         sub proxySub {
             my ( $self, $req ) = @_;
             ...
             # This sub must return a PSGI response. Example
             return [ 302, [ Location => 'http://x.y/' ], [] ];
         }

       This means that requests http://auth.../saml/proxy will be given to proxySub() method.

   Methods that must be provided by an authentication module
       init()

       Method launched after object creation (after each configuration reload). It must return a
       true value if authentication module is ready, false else.

       Methods called at each request

       All these methods must return a Lemonldap::NG::Portal::Main::Constants value.  They are
       called with one argument: a Lemonldap::NG::Portal::Main::Request object.

       Note: if you want to change process() next steps, you just have to change $req->steps
       array.

       extractFormInfo($req)

       First authentication method called during authentication process. It must set $req->user
       that will be used by the userDB object to get user information.

       authenticate($req)

       Last method called during authentication process.

       setAuthSessionInfo($req)

       Method that must at least set $req->{sessionInfo}->{authenticationLevel} to an integer
       that indicates the strong of authentication.

       Proposed levels:

       1: low level
       2: web form level
       3: session based level (Kerberos for example)
       5: strong authentication

       authForce($req)

       authLogout($req)

LOGGING

       Logging is provided by $self->logger and $self->userLogger. The following rules must be
       applied:

       logger->debug: technical debugging messages
       logger->info: simple technical information
       logger->notice: technical information that could interest administrators
       logger->warn: technical warning
       logger->error: error that must be reported to administrator
       userLogger->info: simple information about user's action
       userLogger->notice: information that may be registered (auth success,...)
       userLogger->warn: bad action of a user (auth failure). Auth/Combination transform it to
       "info" when another authentication scheme is available
       userLogger->error: bad action of a user that must be reported, (even if another backend is
       available with Combination)
