How do I hide the parent folder of the user home folders in File Sharing?

I'm running 10.8 server and I have a folder named Users and it is the
parent folder for every local network user's home folder. Now, when the
user connects to the server he sees his home folder, but also the parent
folder Users. He can even list the contents of it.
How can I hide this parent folder? I don't want it to show up at all when
connecting. The only thing the users should see is their home folder.
Nothing else. Since the Users folder is the parent folder, it cannot be
unshared.
Thanks.
