[keycloak-user] Problem with example provider authenticator in version 3.0.0.Final

Hello, I have a problem with the example provider called authenticator which is released with keycloak-demo-3.0.0.Final. After having added the provider, and added the execution "Secret Question" to the browser flow, I don't have a page "Secret Question" while logging into the client app. Instead, I am directly redirected to the application. There is a warning in keycloak's output: "10:48:24,009 WARN [org.keycloak.services.managers.AuthenticationManager] (default task-44) Could not find configuration for Required Action secret_question_config, did you forget to register it?" Did I miss something? Fabien ------ Included: a log in debug, with just the logging of user u, with execution "Secret Question" added. See complete scenario below: I have built the jar authentication-required-action-example.jar and I have put it in the directory keycloak/providers. I run keycloak/bin/standalone.sh In the admin console (http://localhost:8080/auth/admin/master/console/): I create a new realm called "demo", I switch to this realm, I create a user with username "u", I change its password, I create a role "ROLE_USER", I give the role ROLE_USER to user u, I create a client with client ID "test-fabien", redirect URIs http://localhost:8081/*, authorization enabled to ON. I run a test client application with adequate configuration settings. In a private session in Firefox: I type http://localhost:8081/test.html in the address bar, I am redirected to keycloak's authentication page for realm "demo" I enter username u and password, the first time, I am redirected to the password change page, then I am redirected back to the page test.html. In the Authentication part of Keycloak admin console: I copy the brower flow into "Copy of browser", I add the execution "Secret Question", which comes from the added provider, I set it as "required", In the binding tab, I bind "Copy of browser" as browser flow, then save. In a new private session in Firefox: I type http://localhost:8081/test.html in the address bar, I am redirected to keycloak's authentication page for realm "demo" I enter username u and password. Here, I would expect a "Secret Question" page. Instead, I am directly redirected back to the page test.html. In the output of standalone.sh, I can read: "10:48:24,009 WARN [org.keycloak.services.managers.AuthenticationManager] (default task-44) Could not find configuration for Required Action secret_question_config, did you forget to register it?"
