title: Create folder with parent permissions then add another permission
body: <p>In C# I want to add a folder within another folder (or the root of a drive) but I want to copy the permissions of the root folder and then add another user to the new folder ACL as well as the ones from the parent (if that makes sense)</p>
  
  <p>For example... If I have a folder entitled blah and within that folder I want another folder called blah2 I want blah2 to have the ACL permissions of blak plus I want to add authenticated users to that list.</p>
  
  <p>Any ideas?</p>
