[resolved]connection with ldap no login form

Hello,

I would like connect the user with ldap in prestashop in place of the login form.

Is someone did that? How?

I found this in the symfony doc https://symfony.com/doc/3.4/components/ldap.html

I've a script in php who does the connection and retrieve (with functions) the datas.

In classic php script, I do that to have infos :

include_once $_SERVER['DOCUMENT_ROOT'].'/titi/include/authentication.inc.php'; //the script I call for the ldap authentification
if (!$authenticated_user->is_valid()) 
{ 
	header('HTTP/1.0 401 Unauthorized'); 
	print 'Use portal - Ma zone/Mijn zone to access this application'; 
	exit; 
}
//get the service of the person
$service=$authenticated_user->get_service();

In the authentication script, I get the $_SERVER['HTTP_USER_AGENT'] var and I do treatments to do the authentification

/* * -------------------------------------------------------------------- * 
* Toute l'authentification se passe ici !!! 
* l'HTTP_USER_AGENT est de la forme "FedPol-Portal/2.0 445759153F" * 
* -------------------------------------------------------------------- */ 
class Authenticated_User 
{ 
  private $matricule = 0; 
  private $language = ''; 
  private $zone = ''; 
  private $grade=''; 
  private $ldap_data = ''; 
  private $user_found = false; 
  private $ldap_connect; 
  public $sso; 

  public function __construct() { 
    $sso = $_SERVER['HTTP_USER_AGENT']; 
    $this->sso = $sso; $this->matricule = array_pop(explode(' ', $sso)); 
    //$this->language = $this->matricule[strlen($this->matricule)-1]; 
    $this->language=substr($this->matricule,9,1); 
    if(strlen($this->matricule)>11) { 
      $this->zone = substr($this->matricule, 10, 4); 
      $this->grade = substr($this->matricule, 14, 3); 
    } 
    $this->matricule = substr($this->matricule, 0, 9); 
    $this->ldap_connect = ldap_connect(LDAP_HOST); 
    if ($this->ldap_connect) 
    { 
      ldap_set_option($this->ldap_connect, LDAP_OPT_PROTOCOL_VERSION, LDAP_PROTO); 
      $ldap_bind = ldap_bind($this->ldap_connect); /* bind au ldap en anonymous */ 
      if ($ldap_bind) { 
        $search = ldap_search($this->ldap_connect, LDAP_BASE, "(uid=$this->matricule)"); 
        $info = ldap_get_entries($this->ldap_connect, $search); 
        $this->user_found = $info["count"]; $this->ldap_data = $info[0]; 
      } 
    } 
  } 

  public function is_valid() { return $this->user_found; } 

  public function getsso() { return $this->sso; } 

  public function authorize($objectClass, $attributes = true) { // possede t on l'object class dont il est question ? 
    if (in_array($objectClass, $this->ldap_data['objectclass'])) { 
      if ($attributes) { // recuperation du schema LDAP pour determiner les attributs interessants $result = array(); 
        $info = ldap_read($this->ldap_connect, 'cn=subschema', '(objectClass=*)',array('objectclasses')); 
        $entries = ldap_get_entries($this->ldap_connect, $info); 
        foreach ($entries[0]['objectclasses'] as $entry) { 
          if (preg_match("/$objectClass/", $entry)) { 
            $list = ''; 
            if (preg_match('/MUST \(/', $entry)) $list = preg_replace('/.* MUST \((.*?)\).*/','$1',$entry); 
            elseif (preg_match('/MUST/', $entry)) $list = preg_replace('/.* MUST (.*?) .*/','$1',$entry); 
            if (preg_match('/MAY \(/', $entry)) 
            { 
              if ($list) $list .= ' $ '; 
              $list .= preg_replace('/.* MAY \((.*?)\).*/','$1',$entry); 
            } 
            elseif (preg_match('/MAY/', $entry)) 
            { 
              if ($list) $list .= ' $ '; 
              $list .= preg_replace('/.* MAY (.*?) .*/','$1',$entry); 
            } 
            if ($list) 
            { 
            foreach (explode('$', $list) as $attr) $result[trim($attr)]=$this->ldap_data[strtolower(trim($attr))][0]; 
            } 
          } 
        } 
        return array(true, $result); 
      } 
      else return array(true); 
    } 
    else return array(false); 
  } 

  public function get_matricule() { return $this->matricule; } 
  public function get_language() { return $this->language; } 
  public function get_zone() { return $this->zone; } 
  public function get_name() { return $this->ldap_data['cn'][0]; } 
  public function get_service() { return $this->ldap_data['bepolbruservice'][0]; } 
  public function get_mail() { return $this->ldap_data['mail'][0]; } 
  public function get_name2() { return $this->ldap_data['sn'][0].' '.$this->ldap_data['givenname'][0]; } 
  public function get_sn() { return $this->ldap_data['sn'][0]; } 
  public function get_givename() { return $this->ldap_data['givenname'][0]; } 
  public function get_grade() { return $this->grade; } 
  public function get_classes() { return $this->ldap_data['objectclass']; } 
} 

$authenticated_user = new Authenticated_User();

How can I do the same thing in prestashop? 

Is in the AdminLoginController.php (for the backOffice)? And where is the AdminController class?

Thank you for the help

In file /app/config/parameters.php, add the parameters for your ldap connection.

For BackOffice part

In /controllers/admin/AdminLogController.php, add "use Symfony\Component\Ldap\Ldap;" before the class.

In function __construct, I've 

if (!headers_sent()) {
$this->testLdap();
//header('Login: true');
}

And the 2 function I created:

public function testLdap()
{
  //l'HTTP_USER_AGENT est de la forme "FedPol-Portal/2.0 44123456F"
  $sso = $_SERVER['HTTP_USER_AGENT'];
  $ssoPart = array_pop(explode(' ', $sso));
  $langue=substr($ssoPart,9,1);
  $uid = substr($ssoPart, 0, 9);
  $container = $this->buildContainer();
  $host = $container->getParameter('ldap_host');
  $port = intval($container->getParameter('ldap_port'));
  $base = $container->getParameter('ldap_base');
  $classeObject = $container->getParameter('ldap_classe');
  $ldap = Ldap::create('ext_ldap', [
  'host' => $host,
  'port' => $port
  ]);
  $ldap->bind();
  $query = $ldap->query($base, '(&(uid='.$uid.')(objectclass='.$classeObject.'))');
  $results = $query->execute()->toArray();
  $mail = $results[0]->getAttribute("mail")[0];
  $password = $results[0]->getAttribute("userPassword")[0];
  $admin = $results[0]->getAttribute("bePolbruAuthEditShopFin")[0];
  $this->processLoginTest($mail,$password);
}

//it's a copy of processLogin function
public function processLoginTest($email,$passwd)
    {
        /* Check fields validity */
        /*$passwd = trim(Tools::getValue('passwd'));
        $email = trim(Tools::getValue('email'));*/
		
        if (empty($email)) {
            $this->errors[] = $this->trans('Email is empty.', array(), 'Admin.Notifications.Error');
        } elseif (!Validate::isEmail($email)) {
            $this->errors[] = $this->trans('Invalid email address.', array(), 'Admin.Notifications.Error');
        }
		
        if (empty($passwd)) {
            $this->errors[] = $this->trans('The password field is blank.', array(), 'Admin.Notifications.Error');
        } elseif (!Validate::isPasswd($passwd)) {
            $this->errors[] = $this->trans('Invalid password.', array(), 'Admin.Notifications.Error');
        }
        if (!count($this->errors)) {
            // Find employee
            $this->context->employee = new Employee();
            $is_employee_loaded = $this->context->employee->getByEmail($email);
            $employee_associated_shop = $this->context->employee->getAssociatedShops();
            if (!$is_employee_loaded) {
                $this->errors[] = $this->trans('The employee does not exist, or the password provided is incorrect.', array(), 'Admin.Login.Notification');
                $this->context->employee->logout();
            } elseif (empty($employee_associated_shop) && !$this->context->employee->isSuperAdmin()) {
                $this->errors[] = $this->trans('This employee does not manage the shop anymore (either the shop has been deleted or permissions have been revoked).', array(), 'Admin.Login.Notification');
                $this->context->employee->logout();
            } else {
                PrestaShopLogger::addLog($this->trans('Back office connection from %ip%', array('%ip%' => Tools::getRemoteAddr()), 'Admin.Advparameters.Feature'), 1, null, '', 0, true, (int) $this->context->employee->id);

                $this->context->employee->remote_addr = (int) ip2long(Tools::getRemoteAddr());
                // Update cookie
                $cookie = Context::getContext()->cookie;
                $cookie->id_employee = $this->context->employee->id;
                $cookie->email = $this->context->employee->email;
                $cookie->profile = $this->context->employee->id_profile;
                $cookie->passwd = $this->context->employee->passwd;
                $cookie->remote_addr = $this->context->employee->remote_addr;

                if (!Tools::getValue('stay_logged_in')) {
                    $cookie->last_activity = time();
                }

                $cookie->write();

                // If there is a valid controller name submitted, redirect to it
                if (isset($_POST['redirect']) && Validate::isControllerName($_POST['redirect'])) {
                    $url = $this->context->link->getAdminLink($_POST['redirect']);
                } else {
                    $tab = new Tab((int) $this->context->employee->default_tab);
                    $url = $this->context->link->getAdminLink($tab->class_name);
                }

                if (Tools::isSubmit('ajax')) {
                    die(json_encode(array('hasErrors' => false, 'redirect' => $url)));
                } else {
                    $this->redirect_after = $url;
                }
            }
        }
        if (Tools::isSubmit('ajax')) {
            die(json_encode(array('hasErrors' => true, 'errors' => $this->errors)));
        }
    }

In /classes/Employee.php, set the required option for passwd at false.
