How to prohibit to move a share folder within an outliner

I wonder to know how to prohibit an user to perform an action to move/drag a shared folder within an outliner.

In my testing environment(Domino server 6.5.4 and notes client 6.5.4), an user with “Author” equivalent or lower access right in ACL cannot drag/move the folder within an outliner. However, my application should allow the user to create an shared folder/views, only “Editor” access right can do so…so I want to know how to prohibit the user drag/move an folder within an outliner and allow to create an shared folder/view concurrently?

Many thanks.
