title: Where is AuthenticatesUsers on laravel 5.3?
body: <p>I build basic Auth in laravel 5.3 user make:auth. In laravel 5.3 they separate login and register controller in <code>Auth\LoginController</code> and <code>Auth\RegisterController</code>.</p>
  
  <p>Below is my <code>Auth\LoginController</code></p>
  
  <pre><code>&lt;?php
  
  namespace App\Http\Controllers\Auth;
  
  use App\Http\Controllers\Controller;
  use Illuminate\Foundation\Auth\AuthenticatesUsers;
  
  class LoginController extends Controller
  {
      use AuthenticatesUsers;
  
       /**
       * Where to redirect users after login / registration.
       *
       * @var string
       */
      protected $redirectTo = '/home';
  
      /**
       * Create a new controller instance.
       *
       * @return void
       */
      public function __construct()
      {
          $this-&gt;middleware('guest', ['except' =&gt; 'logout']);
      }
  }
  </code></pre>
  
  <p>The problem is when I'm try to edit <code>AuthenticatesUsers</code> in <code>Illuminate\Foundation\Auth\AuthenticatesUsers</code>, that not affected at all. I even try to rename the class/trait name on <code>Illuminate\Foundation\Auth\AuthenticatesUsers</code>, but the script still works.</p>
  
  <p>So where is the actual <code>AuthenticatesUsers</code>? Because my sublime can only find one file with that name.</p>
  
  <p>Thank You</p>
