[keycloak-user] cluster configuration

I am using keycloak 1.1, and tried to configure the cluster with 2 nodes. I am using apache httpd-2.2 as front end for both nodes. The log shows both node. I deployed KeyCloakWebTest.war on both node and without problem to access it. But when I try to access /auth/admin, it did not work: 1. if both nodes are running, after input correct username/password, the same login page will show up again. 2. I stopped one node, login with the same user, it is successful and able to manage my Realms. 3. Then I started the other node, and click on any actions in my already logged in session, the browser will show the login page again and in the newly started node, the following exception show up: 14:22:42,033 WARN [org.jboss.resteasy.core.SynchronousDispatcher] (ajp-/127.0.0.1:8009-2) Failed executing GET /admin/serverinfo: org.jboss.resteasy. spi.UnauthorizedException: Bearer at org.keycloak.services.resources.admin.AdminRoot.authenticateRealmAdminRequest(AdminRoot.java:152) [keycloak-services-1.2.0.Beta1-SNAPSHOT.j ar:1.2.0.Beta1-SNAPSHOT] How can I fix this?
