Auth Controller Help

[AugmentBLU]

Thanks for attempting to get Passport working with OC!

I have attempted to get this working but having an issue with working on an Auth Controller.

The BackendUser::attempt is not a recognised function, here is the controller which is being used with my Routes.

Routes

Route::group(['prefix' => 'api'], function(){
    Route::post('login', 'LukeTowers\Passport\Http\Controllers\API\PassportController@login');
});

Controller

use Request;
use Backend\Classes\Controller;
use LukeTowers\Passport\Models\BackendUser;

class PassportController extends Controller
{
    public $successStatus = 200;

    public function login(){

        if(BackendUser::attempt(['login' => request('login'), 'password' => request('password')])){
            $user = BackendUser::user();

            $success['token'] =  $user->createToken('MyApp')->accessToken;

            return response()->json(['success' => $success], $this->successStatus);
        }
        else{
            return response()->json(['error'=>'Unauthorised'], 401);
        }
    }
}

If I change the Backend User model that you included to extend \BackendAuth instead, and change the login controller function to use BackendUser::authenticate

change $user = BackendUser::user(); to $user = BackendUser::getUser(); it will return an object but it will fail at the $user->createToken('MyApp')->accessToken step.

Any idea if this is directly related to the Passport plugin attempt or a deeper issue with the OC Auth implementation?
