FULL PRODUCT VERSION :
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux 2.6.32-220.13.1.el6.x86_64

A DESCRIPTION OF THE PROBLEM :
The NTLM authentication from Linux does not work as expected. The same code works in windows environment.

1. The sharepoint website is being accessed from java program using HttpUrlConnection which is hosted in windows and required NTLM authentication.
Sample code:
 CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
 Authenticator.setDefault(new MyAuthenticator(userName, password));
URL url = new URL(httpUrl);
HttpURLConnection connection =(HttpURLConnection)url.openConnection();

2. The happens when the user domain(a.company.com) is different from the sharepoint domain(exchad.company.com).
For example :
a. the  user:  a.company.com/user-id has permission setup in sharepoint on a document.
b. the user can access the sharepoint site. 
c. The java program works from windows environment.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
 CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
 Authenticator.setDefault(new MyAuthenticator(userName, password));
URL url = new URL(httpUrl);
HttpURLConnection connection =(HttpURLConnection)url.openConnection();
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
comment out the below line in class com.sun.security.ntlm.Client
under method public byte[] type3(byte[] type2, byte[] nonce) throws NTLMException {

     if (domainFromServer != null) {
         //   domain = domainFromServer;
     }


Note: Here since the user domain is different then the website host domain, the authentication fails only in linux.
