I am using Java Servlets on an NT machine and was wondering how I could go about getting user authentication from the NT domain controller.

It's quite unclear to me just what you are trying to do.  

If it's to authenticate a remote user against the NT user account database, you'll need to call LogonUser() from advapi32.dll to get a token for that user.  Then what you do with the token depends on what you need to accomplish.

If you need to start an application you would use CreateProcessAsUser().  If you need to access a local resource on behalf of that user, you'll need ImpersonateLoggedOnUser().

How any of this is done from a Java Servlet is beyond me, however.  I'd suspect you need to implement this as a native class or use the JNI from JDK 1.2+

I solved the problem using the mod_ntlm module for apache.  It uses the .htaccess file and authenticates via the server.

I'd like to point out that my answer is STILL a valid answer to you question.  The fact that you decided on a different course of action doesn't make it less valid.

Actually, your answer did NOT answer my question.  You mentioned some windows function call, but not how you would use it from a Java servlet.  However, if you are going to cry about it, I'll give you your points.
