-Default behavior of Spring Security is to allow user to submit credentials through form submission. We need to override this behavior and user to authenticate to our API by sending XMLHttpRequest with JSON Payload included.
+By default Spring Security has number of authentication filters implemented and configured in Spring Security filter chain. However, support for Ajax authentication is not added by default. In the first part of this tutorial we will implement support for Ajax authentication by following standard patterns found in Spring Security framework.
