[keycloak-user] Failed to run the Customer-portal Demo on two machines

Hi, I can run the preconfigured Customer-portal demo successfully on the single keycloak-demo-2.0.0.Final distribution by importing the testrealm.json file to create the realm. Everything works fine. And also I can run this simple login/logout demo by following this instruction to install and setup KeyCloak and Wildfly servers separately: https://keycloak.gitbooks.io/getting-started-tutorials/content/v/2.0/topi... However, I failed to run the Customer-Portal demo by trying to set up the KeyClaok server and Wildfly server separately. It always gives me this message as I clicked the "Customer Listing <http://localhost:8080/customer-portal/customers/view.jsp>" link: http://localhost:8080/auth/realms/demo/protocol/openid-connect/auth?respo... I did exactly the same thing as I tested in the KeyCloak-demo distribution by importing the testrealm.json. I didn't configure the subsystem section in the Wildfly 10's standalone.xml, since I believe the "keycloak.json" and "web.xml" in the application's WEB-INF directory will do the same thing. I only had this configured in Wildfly standalone.xml： <security-domain name="keycloak"> <authentication> <login-module code="org.keycloak.adapters.jboss.KeycloakLoginModule" flag="required"/> </authentication> </security-domain> What am I missing? Thank you for your help to this working. By the way, it would be really great to have a full tutorial on how to set up the customer-portal demo on two separate KeyCloak and Wildfly servers by configuring both Json and subsystem file. Thank you for help.
