Hello guys, I am trying to secure an Errai app with Keycloak. I have added the application and user roles to the keycloak server (running as an appliance but with a different port), and also added <auth-method>KEYCLOAK</auth-method> under <login-config> in the web.xml file of the app. However, when I try to test the app (with mvn gwt:run), I get a RuntimeException "caused by Unknown authentication mechanism KEYCLOAK". Any hints as to why this is ?
