Description

I want to extend a website monitoring application to support sites using NTLM (aka: Windows Authentication).
The application is written in Java and uses the HTTPClient/Core 4.2 package, running against sites using basic HTTP authentication and client certificates.

It runs on Windows servers and I would like it to poll NTLM-secured sites too, using the credentials of the current Windows user - NOT having to supply a name&password to the application.

I have tried upgrading to both 4.3 and 4.4-beta1 (with httpclient-win-4.4-beta1.jar).
But I cannot find any way to get the HttpClientBuilder/CloseableHttpClient to use the current user's windows persona.

Is there a way to do this, or will I have to revert to plan B which is to convert the app to .NET (which I would hate to do!).
