Enabling windows authentication for Java application

Question

We are running a Java application hosted on a windows service.

We have the latest version of Jetty web server embedded on the java application.

We are running servlets on the Jetty webserver.

We have a VB application and another Java application consuming these servlets.

We have a requirement:

• to enable windows authentication on the server application.

We tried:

• we tried Waffle but we are observing memory leak while using that.
• we are reluctant to try SPNEGO and other Kerberos based solutions because of the amount of configuration required.

Can someone suggest approaches for enabling widows authentication on Java application hosting Jetty server or just help us with Waffle if we are doing something wrong, following is the code that we have to enable windows authentication on Waffle:

waffle.servlet.NegotiateSecurityFilter securityFilter = 
        new waffle.servlet.NegotiateSecurityFilter();
  FilterHolder filterHolder = new FilterHolder();
  filterHolder.setFilter(securityFilter);  
  EnumSet<DispatcherType> enums = EnumSet.of(DispatcherType.REQUEST);
  enums.add(DispatcherType.REQUEST);  
  servletContext.addFilter(filterHolder, "/*", enums);
