Hi Michal, I was following the thread that you were having for longest prefix matching and security holes in implementing complex access groups. I suggest a reading of the php_PGACL project available at:- http://phpgacl.sf.net This is an implementation of the Generic Access Control List that makes life simpler. By following the principles in the site above, we can actually implement the access control object directly into the gk itself!
