After switch to mongoDB auth::attempt does not work anymore - mongodb

Question

I recently switched my Laravel 4 Project to the mongoDB System using the jenssegers/laravel-mongodb Package.
The Seeds and migrations are fine, but the Auth::attempt function always returns false now. This worked quite nice before.
This is how the attribute looks like in the seeds:
'password' => Hash::make ( 'password' ),
This is how the data is compared by Auth::attempt:
$userdata = array(
'email' =>Input::get('email'),
'password' => Input::get('password'),
);
$loginResult = Auth::attempt($userdata, $post_remember);
I inserted
use Jenssegers\Mongodb\Model as Eloquent;
in all Models, Seeds, Migrations and the controller.
But auth.attempt ALWAYS returns false.

Since you are using Laravel 4 you can fix this by implementing "UserInterface" in your User model.
use Illuminate\Auth\UserInterface;
use Jenssegers\Mongodb\Model as Eloquent;
and then:
class User extends Eloquent implements UserInterface
{
}
For Laravel 5:
use Illuminate\Auth\Authenticatable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Jenssegers\Mongodb\Model as Eloquent;
class User extends Eloquent implements AuthenticatableContract
{
use Authenticatable;
}
