I think you must configure you identity provider to acegi in order to make this work.. I can help you to do this integration but i think no one do this before... I think the right way to do this.. is to make a new identity provider to use you user and credential from acegi and then inject it to other partner in you federation.. in order to auto login in your other site... Please let me know what configuration do you have and what distribution of sites do you want.. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4154452#...
