Security on Solutions

This idea is on the same lines and these feature requests should be merged.

I'm in need for greater security on the solutions groups as I have Agents in roles that don't relate to each other and access to all of the solutions is a problem for us.

I'm wondering if there is any traction with this request?

Do you know; If creating additional portals, are the solutions sections restricted only to agents that are members of those individual portals? Adding security to the solutions is a much better scalable option as creating a portal for each security scenario would be a time consuming task but may work for higher level items.

I would also vote for this security feature also for restricted public view at category level so that we can publish solution articles to specific group of clients.
