Hi Im trying to use NTLM to
get a user name. I keep getting this
error :

jcifs.smb.SmbException: Timeout trying to open socket Failed to establish session with
at Source)

I tried the following :

public void init(ServletConfig config)
throws ServletException
System.out.println("Initializing Servlet "); }
public void doGet( HttpServletRequest req, HttpServletResponse response throws IOException, ServletException

String auth = req.getHeader("Authorization");
if (auth == null)
System.out.println("flushing buffer");
response.setHeader("WWW-Authenticate", "NTLM");
System.out.println("flushing buffer");
if (auth.startsWith("NTLM "))
byte[] msg = new BASE64Decoder(). decodeBuffer (auth.substring(5));
int off = 0, length, offset;
if (msg[8] == 1)
byte z = 0;
byte[] msg1 = {(byte)'N', (byte)'T', (byte)'L', (byte)'M', (byte)'S', (byte)'S', (byte)'P',
z,(byte)2, z, z, z, z, z, z, z,(byte)40, z, z, z,
(byte)1, (byte)130, z, z,z, (byte)2, (byte)2,
(byte)2, z, z, z, z, z, z, z, z, z, z, z, z};
response.setHeader("WWW-Authenticate", "NTLM " +
new sun.misc.BASE64Encoder().encodeBuffer(msg1));
else if (msg[8] == 3)
off = 30;

length = msg[off+17]*256 + msg[off+16];
offset = msg[off+19]*256 + msg[off+18];
String remoteHost = new String(msg, offset, length);

length = msg[off+1]*256 + msg[off];
offset = msg[off+3]*256 + msg[off+2];
String domain = new String(msg, offset, length);

length = msg[off+9]*256 + msg[off+8];
offset = msg[off+11]*256 + msg[off+10];
String username = new String(msg, offset, length);


please help ? Do I need extra info in my web.xml ? Here it is :

<servlet-name>NTLM Servlet</servlet-name>
<servlet-name>NTLM Servlet</servlet-name>
