[keycloak-dev] Application Clustering problems

Hello, I am running some tests with my application cluster being secured by a single keycloak server instance and I encountered problems with the adapter. My application cluster contains 2 nodes and is load balanced by nginx. For testing purposes, I enabled round robin load balancing which is probably the "cause" for my issues. When I access a secured page, I get redirected to keycloak and everything is fine. When I then login, and keycloak redirects me back to the application, I get to a different application cluster node because of round robin. On that node, apparently the initial information of the client session is not available and I get redirected to keycloak login page again. Then keycloak redirects me back to the application, this time to the original node, and says that access is forbidden. I suppose the web session caches are not in sync but I just used the default cache containers as they are defined in standalone-ha.xml of my Wildlfy 10 CR4. Clustering with jgroups works, as I use other distributed caches too which work just fine. We are using Keycloak 1.8.0.CR2 on a Wildfly 10 CR4 Regards, Christian
