subdomain and Authenticate session

I am using Laravel 5 that have a subdomain for each user profile. I have already the sessions table in my database and this is my config/session.php

return [
'driver' => env('SESSION_DRIVER', 'database'),
'lifetime' => 120,
'expire_on_close' => false,
'encrypt' => true,
'files' => storage_path('framework/sessions'),
'connection' => null,
'table' => 'sessions',
'lottery' => [2, 100],
'cookie' => 'laravel_session',
'path' => '/',
'domain' => '.stagedevelopment.dev',
'secure' => false,
'http_only' => true,
];

This is my routes.php this will be called once the user is trying to login

Route::group(['domain' => '{account_alias}.'.stagedevelopment.dev'], function () {
                Route::get('dashboard', 'DashController@index');
...

this is on the 'DashController@index' on DashController.php

public function index(Request $request, $account_alias = null){
   if ( Auth::user()){
    // CODES TO CALL THE VIEW
   }
}

In my sign-in in UserController I modified it like this.

public function postSignIn( Request $request) {
        $rules = array(
            'email' => 'required|email',
            'password' => 'required',
        );
        $validator = Validator::make( Input::all(), $rules );
        if ( $validator->passes() ){
            $remember = ( !is_null( $request->get('remember')) ? true : false );
            if ( Auth::attempt( array( 'email' => $request->input('email'), 'password' => $request->input('password') ) ) ){
                if ( Auth::check() ){
                        $account = \App\Account::where( 'alias', 'LIKE', Auth::user()->account->alias )->get();
                        if($account->count() > 0){
                            return Redirect::to('http://'. Auth::user()->account->alias.'http://.stagedevelopment.dev/app/dashboard');
                        }
                }
            }
        }
    }

My issue now is when I login a user, it won't authenticate by retrieving using Auth::check() or Auth::user(). But when I try to retrieve using $request->session()->get('uid') it returns the user_id of the user and it will return null when I call on Auth::logout().

question, did I missed something in my code? or if not, how can I put the $request->session()->get('uid') into Auth::user() and Auth::check() ?
