public function index()
{
   $db = new Database();
   $index = new View('Index'); // unused var?
   //$db->connect();
   $name = Arr::get($_POST, 'name');
   $password = Arr::get($_POST, 'password');
   if ( ! $name OR !$password)
   {
      die('name and password required!');
   }
   $user = $db->select('*')   // use Query Builder!
           ->from('users')
           ->where('username', $name)
           ->get();
   if ( empty($user))
   {
      die('user '.$user.' not found!');
   }
   $user = current($user);
   if ($user['password'] == $password)
   {
       // correct password
   }
   else
   {
       die('wrong username/password combination!');
   }

}

Its for Kohana v2.3.4 (3.x has another controllers and methods name convention)
