<?php

// External login module : LDAP
/**
 * This file is included by main/inc/local.inc.php when extldap is activated, a user try to login
 * and chamilo does not find his user
 * Variables that can be used :
 *    - $login : string containing the username posted by the user
 *    - $password : string containing the password posted by the user.
 *
 * Please configure the exldap module in main/auth/external_login/ldap.conf.php
 *
 * If login succeeds, we have to add the user in the chamilo database and then
 * we have 2 choices :
 *    1.  - set $loginFailed to false,
 *        - set $_SESSION['_user']['user_id'] with the dokeos user_id
 *        - set $uidReset to true
 *        - let the script local.inc.php continue
 *
 *    2.  - set $_SESSION['_user']['user_id'] with the dokeos user_id
 *        - set $_SESSION['_user']['uidReset'] to true
 *        - upgrade user info in dokeos database if needeed
 *        - redirect to any page and let local.inc.php do the magic
 *
 * If login fails we have also 2 choices :
 *    1.  - unset $_user['user_id']
 *        - set $loginFailed=true
 *        - set $uidReset =  false
 *        User wil then have the user password incorrect message
 *
 *    2. We redirect the user to index.php with appropriate message :
 *        Possible messages are :
 *          - index.php?loginFailed=1&error=access_url_inactive
 *          - index.php?loginFailed=1&error=account_expired
 *          - index.php?loginFailed=1&error=account_inactive
 *          - index.php?loginFailed=1&error=user_password_incorrect
 *          - index.php?loginFailed=1&error=unrecognize_sso_origin');
