Check Auth::user() from middleware - laravel

Question

I try to check in middleware if user is authenticated by calling Auth::user()
But it returns null. I call this middleware last in list of protected $middleware section in Kernel.php. Is there an way to check from middleware if user is authenticated or how I should do it another way?
Addition: I'm using Zizaco Entrust. May be it is why it doesn't work
And I'm using Laravel 5.5
my app/HTTP/Kernel.php:
class Kernel extends HttpKernel
{
/**
* The application's global HTTP middleware stack.
*
* These middleware are run during every request to your application.
*
* #var array
*/
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
\App\Http\Middleware\TrimStrings::class,
\Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
\App\Http\Middleware\TrustProxies::class,
\App\Http\Middleware\FirstLoginPasswordChange::class,
];
my FirstLoginPasswordChange middleware:
use Illuminate\Support\Facades\Auth;
use Zizaco\Entrust\Entrust;
public function handle($request, Closure $next)
{
dd(Auth::user()); // returns null
// or
dd(Auth::check()); // returns false
// or
dd(\Entrust::user()); // returns null
return $next($request);
}
}

Answer 1

problem solved by moving middleware from protected $middleware section in Kernel.php to protected $routeMiddleware section in Kernel.php

To check if user is authenticated you can do as Laravel Docs states:
use Illuminate\Support\Facades\Auth; //be sure to add the facade
if (Auth::check()) {
// The user is logged in...
}
If you are trying to get user details and do some logic, then you can do this in your middleware:
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
$role = Auth::user()->role; //Obtenemos el rol del usuario
if ($role != "user"){
return redirect('/logout');
}
return $next($request);
}
}
