ntlm authentication
I have a Web application online running on a Linux server. I need to access files located on a private network running Windows server. The client has given me a public IP which uses port 8080 that I can use to access the reources that I need.
If I type the IP plus the port in IE like so: http://[my ip addres]:8080 I get the prompt to enter the appropriate user and password. When I enter the user and password that were given to me by the client, I’m able to access the directories that I need.
Now, I want to this from my application without user intervention. In other words, I want to be able to pass the IP, port, userid and password from within my routine and then access the necessary resources.
I’ve been working with several samples but the result is always the same. When I run the JSP page, I get prompted for the userid and password.
Could you please take a look at the code snippet and give me a heads-up.
HttpClient client = new HttpClient();
// Set credentials on the client
Credentials credentials = new NTCredentials("userid", "password",
"http://0.0.0.0:8080", null);
//HttpState state = client.getState();
//state().setCredentials(null, null, credentials);
client.getState().setCredentials(null, null, credentials);
String url = "http://0.0.0.0/PathToFiles";
HttpMethod method = new GetMethod(url);
client.executeMethod(method);
// String responseStr = method.getResponseBodyAsString();
// System.out.println(responseStr);
// method.releaseConnection();
String redirectURL = "http://0.0.0.0:8080/PathToFiles" ;
response.sendRedirect(response.encodeRedirectURL(redirectURL));
Thanks so much for the help

Judging by the code snippet you posted in your first message, you are
still using HttpClient 3.1. So, you need to make sure the target server
is configured to allow older version of the NTLM protocol (NTLMv1).

Which version of HTTPClient are you using?
BTW, HTTPClient 3.x only ever supported NTLMv1, it does not support NTLMv2.

Which version of HTTPClient are you using?
BTW, HTTPClient 3.x only ever supported NTLMv1, it does not support NTLMv2.
