[keycloak-user] How to get online users

Good morning, I am trying to set up an application that uses: 1. Spring 3.2.x I used to have spring security for the authentication of the users, and I could get all the online users by a bean called SpringRegistryImpl. Here is an example how I could get all the logged in users: In the controller class I had: @Autowired private SessionRegistryImpl sessionRegistry; and then: List<Object> principals = sessionRegistry.getAllPrincipals(); for (Object principal : principals) { if (principal instanceof UserDetails) { //Add user to the list with the logged in users (in session). } } Now, I have configured my application’s authentication with keycloak and removed spring-security. How can I retrieve all the users in session with keycloak? Thanks in advance, Jason
