To quote wikipedia:

"The file system permissions of a symbolic link usually have relevance 
only to rename or removal operations of the link itself, not to the 
access modes of the target file which are controlled by the target 
file's own permissions."

So set the owner and group of the link itself to root - or some other 
owner you set up for the purpose if root is not suitable - and remove 
the permissions for anyone other than owner.  That will affect the link 
itself for removal purposes.  For the contents of the linked directory 
set the correct permissions on that directory and its files.
