[keycloak-user] keycloak adapter with apache karaf 4.1.3

Hello, I'd like to use keycloak to secure rest api loaded as a bundle in apache karaf 4. I've tried to use samples provided with keycloak for fuse, it seams they are working with karaf 3 only. Does someone already try to use keyccoak OSGI adapter with Karaf 4 and succeed to use them ? Thks for your answer, Olivier LIEVRE
