title: Auth changes are not reflected laravel 5.3
body: <p>I am new to laravel and want to make few changes like validation for proper email in login and sending user to login page after logout.</p>
  
  <p>I have made these change in AuthenticatesUsers trait but they do not seems working. </p>
  
  <p>I have changed these functions:</p>
  
  <pre><code>    protected function validateLogin(Request $request)
      {
          $this-&gt;validate($request, [
              $this-&gt;username() =&gt; 'required|email', 'password' =&gt; 'required',
          ]);
      }
  
      public function logout(Request $request)
      {
          $this-&gt;guard()-&gt;logout();
  
          $request-&gt;session()-&gt;flush();
  
          $request-&gt;session()-&gt;regenerate();
  
          return redirect('/login');
      }
  </code></pre>
  
  <p>Any help will be appreciated. Thanks.</p>
