[keycloak-user] Keycloak working with Spring Boot / Spring Security OAuth?

Hi. I am trying to get this sample application working against a local keycloak instance https://github.com/spring-cloud-samples/sso As I understand it, it's a Spring Boot application using Spring Security to support SSO. And I can't get it (as the client) to interact with the KeyCloak authentication server. If I just add the configuration for the Spring Boot adapter alone, it attempts to call out to KeyCloak but the url always includes a redirect_uri parameter, which Keycloak doesn't like and displays an error instead of a login screen. I've then tried to add, in addition to the Spring Boot configuration, the integration with Spring Security (the next section in the KeyCloak documentation). When I that, however, the server complains because it cannot find the keycloak.json file. Which isn't there because I've added the details to the application.yml file (as directed by the Spring Boot config) Is there some last step that I need to do to get these working? I'm new to Spring Boot. so I'm not sure I know how to step through it's configuration to see why it insists on sending the redirect_uri, and including Spring Security seems like a miss. Thanks for any help, Ed
