* This is passed to the ZAP handler in the 'domain' field * If not set, or empty, then NULL security does not call the ZAP handler * This resolves the phantom ZAP request syndrome seen with sockets where security was never intended (e.g. in test cases) * This means if you install a ZAP handler, it will not get any requests for new connections until you take some explicit action, which can be setting a username/password for PLAIN, a key for CURVE, or the domain for NULL.
