Problem with permissions on MyCloud

I recently bought the WD My Cloud and I am struggling with one problem:
I have multiple users in the network with permissions to different folders. The folders that are with deny access are still visible on Windows 7. On OSX they are not showing
How I can make the folders not show if they are forbidden?

There have been past discussions, that can be found using the forum search feature, magnifying glass icon upper right, that discuss possible methods of attempting to hide Shares that are configured for Private through the My Cloud Dashboard from users who are denied access. On will most likely have to use SSH to possibly modify the My Cloud firmware. Here is one such discussion with links to other discussions:
