[Typo3] CURIFSUB - hiding access restricted (hidden) menu items ???

[Rainer (Rene) Suthoelder]

hi!

i was wondering if anyone of you has experienced the same with the CURIFSUB 
function:

if you use the suggested CURIFSUB script (to generate menus with icons 
indicating sub-menus) from a prevoius post in this list

<?php
function user_curifsub($menuArr,$conf)    {
  while(list($k,$v)=each($menuArr))    {
    if ($conf["parentObj"]->isItemState("IFSUB",$k) &&
    $conf["parentObj"]->isItemState("CUR",$k))
    $menuArr[$k]["ITEM_STATE"]="USERDEF1";
  }
  return $menuArr;
}
?>

the different item menu states get rendered properly, but if you have access 
restricted (hidden) menu subitems, they are also detected and the menu shows 
the "click to drill deeper" item state.

i think that you would expect this behavour _only_ if you are a member of a 
group which has appropriate access-rights, all others should not be able to 
see hidden menu-tree.

so my question:
is there a way to add another AND statement within this line

    if ($conf["parentObj"]->isItemState("IFSUB",$k) &&
    $conf["parentObj"]->isItemState("CUR",$k))

i.e. something like (in plain words)

... && user_has_access_rights_for_sub_tree))

or perhaps someone has another solution for this scenario?

greets,
