Hi
I'm trying to implement the following code to Authenticate users using Shibboleth like we used to do on version 3, but I'm getting the following error when I've tried to test the shibd user variable:PHP warningUndefined array key "eppn"/opt/limesurvey/plugins/AuthAAI/AuthAAI.php(20)08 public $allowedPublicMethods = array();

This is the code:
<?php

{
protected $storage = 'DbStorage';
static protected $description = 'Autenticação federada shibboleth';
static protected $name = 'AuthAAI';
public function init()
{
// Registra os eventos que o plugin vai escutar
$this->subscribe('beforeLogin');
$this->subscribe('newUserSession');
}
public function beforeLogin()
{
echo $_SERVER; //for testing
// Verifica se a variável $_SERVER existe
if (isset($_SERVER)) {
// Usa a variável como username
$username = $_SERVER;
// Tenta encontrar o utilizador no banco de dados
$user = $this->api->getUserByName($username);
if ($user === null) {
// Se o utilizador não existe, cria um novo com permissão de participante
$user = new User;
$user->users_name = $username;
$user->password = hash('sha256', createPassword());
$user->full_name = $_SERVER;
$user->parent_id = 1;
$user->lang = 'pt-PT';
$user->email = $_SERVER;
if ($user->save()) {
// Atribui a permissão de participante ao utilizador
Permission::model()->setGlobalPermission($user->uid, 'surveys', array('create_p'));
// Dispara o evento de novo utilizador
$this->getEvent()->set('newUser', true);
} else {
// Se houver algum erro ao salvar o utilizador, mostra uma mensagem de erro
$this->getEvent()->set('error', 'Não foi possível criar o utilizador.');
}
}
// Se o utilizador existe, autentica
if ($user !== null) {
// Dispara o evento de nova sessão de utilizador
$this->setUsername($user);
$this->setAuthSuccess($user);
$this->setAuthPlugin(); // This plugin will handle authentication and skips the login form
}
} else {
// Se a variável não existe, mostra uma mensagem de erro
$this->getEvent()->set('error', 'Não foi possível obter a variável $_SERVER[\'eppn\'].');
}
}
public function newUserSession()
{
// Obtém o utilizador autenticado
$user = $this->getEvent()->get('user');
if ($user !== null) {
// Atualiza a última data de login do utilizador
$user->setAttributes(array('last_login' => date('Y-m-d H:i:s')));
$user->save();
}
}
}
I've tried the same echo, even with a function on the same Limesurvey parent directory, and I'm getting the variable just fine.
Thank you in advance.
