Unable to use cps portlets in wci

 I'm building a test-server with wci, ucm and cps portlets to make them work together. I did install ucm and tested it via its direct clients
I did install wci and created a portal structure with collaboration portlets.
On the ucm machine I did install weblogic-portal for producing wsrp portlets and configured them using the installation guide.
I did install wsrp consumer on the wci machine and created the portlets connected to the "produced ones.

At the moment I can add portlets on my portal, but the only content is: "no user registered. please logon to the portal (translated from italian)"
