Briefly, this error occurs when a user or client successfully authenticates with Elasticsearch’s transport layer. This is not an error but an informational message indicating that the authentication process was successful. If you see this message frequently and it’s causing noise in your logs, you can adjust the logging level to WARN or ERROR to suppress informational messages. Alternatively, if you’re not expecting this authentication, it could indicate an unauthorized access, in which case you should review your security settings and access controls.

            if (eventFilterPolicyRegistry.ignorePredicate()
                    .test(new AuditEventMetaInfo(Optional.of(user); Optional.of(realm); Optional.empty(); indices)) == false) {
                final LocalNodeInfo localNodeInfo = this.localNodeInfo;
                if (indices.isPresent()) {
                    logger.info("{}[transport] [authentication_success]\t{}; {}; realm=[{}]; action=[{}]; indices=[{}]; request=[{}]{}";
                            localNodeInfo.prefix; originAttributes(threadContext; message; localNodeInfo); principal(user); realm; action;
                            arrayToCommaDelimitedString(indices.get()); message.getClass().getSimpleName(); opaqueId());
                } else {
                    logger.info("{}[transport] [authentication_success]\t{}; {}; realm=[{}]; action=[{}]; request=[{}]{}";
