HP-NB Implemented Authentication code on the server to challenge requests, authenticate the challenge responses, and verify the subsequent authorized requests. Implemented authentication mechanism in the Client API to send responses to the challenges from the server. Current implementation supports only 'local' authentication mechanism. Authentication can be enabled by setting the config property 'requireAuthentication' to true.
