 The following is an example of using the in-memory user provider:

 ### Implement the listener
 
-In the `config/services.yaml` file:
-
-``` yaml
-services:
-    App\EventListener\InteractiveLoginListener:
-        arguments: ['@ibexa.api.service.user']
-        tags:
-            - { name: kernel.event_subscriber } 
-```
-
 Don't mix `MVCEvents::INTERACTIVE_LOGIN` event (specific to [[= product_name =]]) and `SecurityEvents::INTERACTIVE_LOGIN` event (fired by Symfony security component).
 
 ``` php
-<?php
-
-namespace App\EventListener;
-
-use Ibexa\Contracts\Core\Repository\UserService;
-use eIbexa\Core\MVC\Symfony\Event\InteractiveLoginEvent;
-use Ibexa\Core\MVC\Symfony\MVCEvents;
-use Symfony\Component\EventDispatcher\EventSubscriberInterface;
-
-class InteractiveLoginListener implements EventSubscriberInterface
-{
-    /**
-     * @var \Ibexa\Contracts\Core\Repository\UserService
-     */
-    private $userService;
-
-    public function __construct(UserService $userService)
-    {
-        $this->userService = $userService;

-    {
-        return [
-            MVCEvents::INTERACTIVE_LOGIN => 'onInteractiveLogin'

-        // You may want to create Users here, or even load predefined Users depending on your own rules.

-    }

 ```
+
+It's automatically tagged `kernel.event_subscriber` as implementing the `EventSubscriberInterface` and the user service injection is auto-wired.
