Listing Access Permissions on an OU

i have small script trying reset permissions on ou.  at point trying learn can or can't done , @ point of listing current permissions defined on ou , can't seem list permissions.  anyone know have misconfigured in code below? 

the $childou.name work , can members list back.  i can list full code (it 27 lines) thought list problem is, since hope not doing correctly.  the failure seems in foreach($access in $accesslist)

 
  {
   $childou.name
   $oude = $childou.directoryentry
   $accesslist = $oude.objectsecurity.access

   foreach($access in $accesslist) 
      {
       $access.identityreference          # list account name
       if($access.identityreference -eq "everyone"){write-host "found everyone"}
       else {write-host "found nothing"}
      }

}
