Java – Apache HttpClient 4.1.1 NTLM authentication not SPNEGO

The problem here is consuming a web resource that has NTLM authentication while using the Apache HttpClient on the client side. The issue I am having is forcing the client to use NTLM authentication. here is a code sapmle.

DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.getAuthSchemes().register("ntlm",new NTLMSchemeFactory());
NTCredentials creds = new NTCredentials("_myUSer_","_myPass_","_myWorkstation_","_myDomain_");
httpclient.getCredentialsProvider().setCredentials( new AuthScope("serverName",80), creds);
List<String> authpref = new ArrayList<String>();
authpref.add(AuthPolicy.NTLM);
httpclient.getParams().setParameter(AuthPNames.PROXY_AUTH_PREF, authpref);
HttpHost target = new HttpHost("serverName", 80, "http");
HttpGet httpget = new HttpGet("webResource");
HttpContext localContext = new BasicHttpContext();
HttpResponse response = httpclient.execute(target, httpget, localContext);

Here is the error from Java:

org.apache.http.client.protocol.RequestTargetAuthentication process
SEVERE: Authentication error: Invalid name provided (Mechanism level: Could not load configuration file C:\WINDOWS\krb5.ini (The system cannot find the file specified))

The web server response is a 401.

Any ideas on why the auth policy not being set correctly?
Am I missing something in the code?
