[keycloak-user] Getting the current user name in EJB

Hi All, Am trying to get the name and surname of the currently connected user by doing this : import java.io.Serializable; import java.security.Principal; import javax.annotation.Resource; import javax.annotation.security.RolesAllowed; import javax.ejb.EJBContext; import javax.ejb.LocalBean; import javax.ejb.Stateless; import org.jboss.ejb3.annotation.SecurityDomain; @Stateless(name="myEJB") @LocalBean @SecurityDomain("keycloak") public class MyEJB implements Serializable { private static final long serialVersionUID = 1L; @Resource private EJBContext ejbContext; @RolesAllowed("ADMIN") public void test() { Principal principal = ejbContext.getCallerPrincipal(); System.out.println("principal.getName() = " + principal.getName()); } } This works nicely as i get a 403 if my currently connected user does have the role : ADMIN. My question is : does keycloak propagate the username or any other information that would help me get the first name and last name of the currently connected user ? Unfortunately, principal.getName() returns a string like this : edd42240-85bf-4724-8d79-5374338506b7 which i don't know the interpretation ! Thanks for any help.
