You enable EventFlow engine API listener authentication and authorization by activating a ClientAPIListener root object of
                  configuration type sbclientapilistener that contains an authenticationRealmName property whose value is the name of an authentication realm. That realm's configuration file must be activated before the
                  listener's configuration, or the reference to the realm fails to resolve and the activation attempt fails.
               
You enable LiveView engine API listener authentication and authorization by activating a ClientAPIListener root object of
                  configuration type ldmclientapilistener that contains an authenticationRealmName property whose value is the name of an authentication realm. That realm's configuration file must be activated before the
                  listener's configuration, or the reference to the realm fails to resolve and the activation attempt fails.
               
You specify node administration authentication and authorization realms with the epadmin setadmin realm command and the realm name. That realm's configuration file must be activated before the command is invoked, or the reference
                  to the realm fails to resolve and the command fails. If you do not specify a realm name, the realm used is the default local
                  authentication realm named default-realm.
