title: Changing redirect url for login in laravel 5.6.3
body: <p>I installed the adminlte theme and I want to create an admin area. 
  So my url should look like : </p>
  
  <pre><code>/admin =  admin home page dashboard
  /admin/login
  /admin/register/
  </code></pre>
  
  <p>This is my route so far:</p>
  
  <pre><code>Route::group(['middleware' =&gt; 'auth'], function () {
      Route::get('/admin', ['as' =&gt; 'admin', 'uses' =&gt; 'Admin\DashboardController@index']);
  });
  </code></pre>
  
  <p>When I access the <code>/admin</code> page I am redirected to <code>/login</code> instead of <code>/admin/login</code></p>
  
  <p>The redirection is made from here: </p>
  
  <pre><code>vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php
  </code></pre>
  
  <p>in the <code>unauthenticated</code> method</p>
  
  <p>I followed up the answer from here: <a href="https://stackoverflow.com/questions/45340855/laravel-5-5-change-unauthenticated-login-redirect-url">Laravel 5.5 change unauthenticated login redirect url</a> ,but i ended up with this error:</p>
  
  <pre><code>Declaration of App\Exceptions\Handler::unauthenticated($request, App\Exceptions\AuthenticationException $exception) should be compatible with Illuminate\Foundation\Exceptions\Handler::unauthenticated($request, Illuminate\Auth\AuthenticationException $exception)
  </code></pre>
  
  <p>Any idea how do I change my redirect url ?  Thank you</p>
