D7 port not working

found:

//alternative login function to check against uid instead of username
function uid_login_validate($form, $form_state) {
  global $user;
  $values=$form_state['values'];
  if (!empty($values['name']) && !empty($values['pass']) && $account = user_load(array('uid' => $values['name'], 'pass' => trim($values['pass']), 'status' => 1))) {
    $user = $account;
    user_authenticate_finalize($values);
    return $user;
  } else {
    user_login_final_validate($form, $form_state);
  }
}

and replace on

//alternative login function to check against uid instead of username
function uid_login_validate($form, $form_state) {
  global $user;
  $values=$form_state['values'];
  if (!empty($values['name']) && !empty($values['pass']) && $account = user_load($values['name'])) {
    // !!Argument to a load() function *must* be a single id
    $user = $account;
    user_login_finalize($values);
    // !! it is no "user_authenticate_finalize" function in drupal 7
    return $user;
  } else {
    user_login_final_validate($form, $form_state);
  }
}

now i have a error (incorrect user name or password), but already can log in...

DO NOT USE THIS CODE!!!
i found a big mistake in it!
