Java, Client-Side NTLM Authentication
<p>I'm charged with building an app health monitoring system, and one of the requirements is to check both if our various java services are up and if our reverse proxy is up. The reverse proxy is a .NET application that gets a user's AD Groups and passes them along to our apps via a header for monitoring/security reasons.</p>

<p>Obviously the rinky dink input and output stream http request isn't enough, but I haven't found information or guides about client-side NTLM authentication for Java.</p>

<p>I'm guessing there's a library (probably Oracle or Apache) that provides a handler that can do this, but I have come up empty trying to find it. Please help.</p>
