In 5/2011 there was a great post about Single Sign on (see url below). In the post Chad did a good job of clarifying that the single sign on was for DNN parent and child portals only and not domain portals within a single DNN install.
In other words the SSO will work for: portalA.com and portalA.com/schools. But will not work for: portalA.com and portalB.com even if both of these portals are under the same DNN install.
Is that still true? I am looking for SSO solution between two domain portals within the same DNN install.
