Hi
I would like to enable singlesignon on vertical cluster environment [multi-nodes on multiple hosts]. We are using clustersinglesignon under host element, and this works in horizontal cluster, but does not work in vertical cluster environment. Is there any way to make this work as part of tomcat configuration? When the node goes down, and a user may be routed to the node located in a different host, it will ask a user to relogin again under the current setup. We would like to avoid a user for relogging to the application. Anyway, if tomcat does not provide singlesigeon solution for vertical cluster, is there any other open source solutions available?
