Drupal 7 version still shows menu item when access is resticted

Hey,

This module works as expected, except the menu access isn't kicking in.

Although my anonymous users can't access the page, the can still see it in the menu bar.

This is happening in a custom menu, using the following code to print the menu:

<?php
  $vars['utility_menu'] = theme('links__menu_utility_menu', array(
    'links' =>  menu_navigation_links('menu-utility-menu'),
    'attributes' => array('class'=>array('inline-menu'))
  ));
?>
