Override Spark authentication in order to receive the password of the authenticated user.

Hi everyone,

During the login process of Spark I need to be able to request a token of a remote API. This API stores the exact same users and passwords as the Laravel Spark application. Therefore I need to get the username and non hashed password of the user during the authentication process.

I thought overriding the authenticated method would be the solution to my problem. In routes/web.php I override the POST /login endpoint and am pointing this endpoint to my own LoginController:

<?php

namespace App\Http\Controllers\Auth;

use Illuminate\Support\Facades\Log;
use Illuminate\Http\Request;
use Laravel\Spark\Http\Controllers\Auth\LoginController as SparkLoginController;

class LoginController extends SparkLoginController
{
    /**
     * Create a new login controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Handle a successful authentication attempt.
     *
     * @param  Request  $request
     * @param  \Illuminate\Contracts\Auth\Authenticatable  $user
     * @return Response
     */
    public function authenticated(Request $request, $user)
    {
        Log::info('authenticated method in LoginController has been called');

        return parent::authenticated($request, $user);
    }
}

This implementation throws a Missing argument 2 for App\Http\Controllers\Auth\LoginController::authenticated() exception. Somehow Laravel is not passing a User in the $user parameter. This exception is thrown whatever I do. Even removing the method out of my LoginController will result in the same exception thrown in the Spark LoginController.
