Change Authentication Table, Laravel 5

I am making a platform that will have 3 authentication systems, one for ordinary users, another for admins, and one for workers.

I thought changing the model and table in config-> auth would be enough but apparently it was not.

ObreirosController:

class ObreiroController extends Controller
{
    public function __construct() {
        Config::set('auth.model', 'App\Obreiros');
        Config::set('auth.table', 'obreiros');
    }

    public function doLogin(Request $request) {

        $credentials = array(
            'username' => $request->input('username'),
            'password' => $request->input('password'),
        );

        if(!Auth::attempt($credentials)) {
            Session::flash('flash_error', 'Something went wrong with your login chef');
            return redirect('/');
        }

        Session::set('auth', 'obra');
        return redirect('/obra/dashboard');
    }

    public function goDashboard() {
        return view('/obreiro/dashboard');
    }
}

UserController:

class UserController extends Controller
{
    public function __construct() {
        Config::set('auth.model', 'App\User');
        Config::set('auth.table', 'users');
    }

    public function doLogin(Request $request) {

        $credentials = array(
            'email' => $request->input('email'),
            'password' => $request->input('password'),
        );

        if(!Auth::attempt($credentials)) {
            Session::flash('flash_error', 'Something went wrong with your login chef');
            return redirect('/');
        }

        Session::set('auth', 'user');
        return redirect('/user/dashboard');
    }

    public function goDashboard() {
        return view('/user/dashboard');
    }
}

And the same for AdminController ...

The Middleware:

class UserAuth
{

    public function handle($request, Closure $next)
    {
        $sessAuth = 'user';

        if (Auth::user() && Session::get('auth') == $sessAuth) {
            return $next($request);
        }
        else if (Auth::user() && Session::get('auth') != $sessAuth) {
            Session::flash('flash_session_off', 'YOU SHALL NOT PASS' .$sessAuth);
            return redirect('/');
        }
        Session::flash('flash_session_off', 'you are off chef, please login again');
        return redirect('/');
    }

That is the same in all three, except for $sessAuth

Routes ex:

Route::group(['middleware' => 'userAuth'], function() {
    Route::get('/user/dashboard', 'UserController@goDashboard');
});
Route::post('/auth/user', 'UserController@doLogin');

That's also the same in all three ...

views / worker / dashboard:

Hello {{Auth::user()->username}}

It seems to be fine but when I try to print the username, which is a column that exists in the obreiros table but does not exist in the table users , {{Auth::user()->username}} it does not print anything to me, it seems to be an empty string , but it is not. I believe you are not changing the authentication table, which is always the users , but it does not give any errors, how do I solve this? Any better way to do this?
