Bonjour à tous,
voilà je me permet de vous exposer mon problème, je travail sur une authentification pour un intranet et en fait je dois intégrer un script d'authentification dans un snippet du CMS MODx.
Le problème est que je n'arrive pas à trouver à quel endroit précis se fais l'authentification dans le fichier de ce snippet.

Voici le code du snippet

<?php
# WebLogin 1.0
# Created By Raymond Irving 2004
#::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::


defined('IN_PARSER_MODE') or die();

# load tpl
if(is_numeric($tpl)) $tpl = ($doc=$modx->getDocuments($tpl)) ? $doc['content']:"Document '$tpl' not found.";
else if($tpl) $tpl = ($chunk=$modx->getChunk($tpl)) ? $chunk:"Chunk '$tpl' not found.";
if(!$tpl) $tpl = getWebLogintpl();

// extract declarations
$declare = webLoginExtractDeclarations($tpl);
$tpls = explode((isset($declare["separator"]) ? $declare["separator"]:"<!--tpl_separator-->"),$tpl);

if(!isset($_SESSION['webValidated'])){
    ob_start();
//    if(isset($_COOKIE[$cookieKey])) {
//        $cookieSet = 1;
//        $sitename = $_COOKIE[$cookieKey];
//        $thepasswd = substr($site_id,-5)."crypto"; // create a password based on site id
//        $rc4 = new rc4crypt;
//        $thestring = $rc4->endecrypt($thepasswd,$sitename,'de');
//        $uid = $thestring;
//    }else{
        $uid = isset($_POST['username'])? $modx->db->escape(htmlspecialchars($_POST['username'], ENT_QUOTES)):'';
        echo $modx;
//    }

Si quelqu'un arrive a trouver la ou les lignes d'authentification merci de me le faire savoir
