Keycloak Remote User Provider

Deploy

• Copy target/remote-user-federation-jar-with-dependencies.jar to /opt/keycloak/providers/remote-user-federation-jar-with-dependencies.jar

When user federation is enabled, the user list will not load data initially and needs to be searched manually. Tip: To search for all users, use * in the search.
