title: Keycloak Unknown authentication mechanism
body: <p>I need help with using keycloak in an Errai app. I am getting an error about "unknown authentication method" for "KEYCLOAK" ? I have the keycloak-appliance running (on a different port though), and the Errai app has a  with KEYCLOAK in the web.xml file inside WEB-INF
  When I run the Errai app with mvn gwt:run, I get  : RuntimeException caused by "Unknown authentication mechanism KEYCLOAK". I have no idea how to go around this issue .</p>
