Thanks, Marco. I was able to move forward by using the latest adapter you pointed me to. I was able to bring up the Wildfly 9.0 server with the adapter installed and was able to install the Customer-Portal and Product-Portal example apps successfully. But, when I install the Database example app, I get the following error. Any tips on how to resolve this error ? Thanks.

Use the latest keycloak-wf9-adapter-dist from the download site: http://keycloak.jboss.org/keycloak/downloads.html?dir=0%3Dadapters/keycloak-oidc%3B

You're trying to use latest config syntax with an old version that uses a different kind of config, and is outdated.

I am getting the following exception after unzipping the keycloak-wildfly-adapter-dist-1.1.0.Final.zip into the WildFly 9.0 server and configuring the standalone.xml file with the following lines as described in the keycloak documentation. I have tried this with Wildfly 10.0 version also and get the same error.
<server xmlns="urn:jboss:domain:1.4"> <extensions> <extension module="org.keycloak.keycloak-adapter-subsystem"/> ... </extensions> <profile> <subsystem xmlns="urn:jboss:domain:keycloak:1.1"/> ... </profile>

How do I resolve this keycloak module loading exception?
