Yes, I got this to work by adding this:
// Sets whether authentication should be attempted preemptively.
client.getParams().setAuthenticationPreemptive( true );
Thanks!

Ok....figured this one out. Add this:

And it seems to work perfectly. No idea why! Anyone?
This is because BASIC authentication (read: username/password sent in
clear text) is used to authenticate preemptively, not NTLM.
Apparently the credentials are OK, since you are able to authenticate
using BASIC. So, most likely the server has been configured to use
NTLMv2 only, whereas HttpClient supports NTLMv1 only.

Thx.

Hello All,
I am trying to authenticate to MS Exchange as follows:
HttpClient client = new HttpClient();
NTCredentials creds = new NTCredentials(_username, _password,
"localhost", _domain);
// set credentials for connection
client.getState().setCredentials(new AuthScope(_exchangeServer,
AuthScope.ANY_PORT, AuthScope.ANY_REALM), creds);
GetMethod get = new GetMethod(prootPath);
get.setDoAuthentication(true);
status = client.executeMethod(get);
When I hit the server I get this back:
Jan 10, 2008 3:10:54 PM
org.apache.commons.httpclient.auth.AuthChallengeProcessor
selectAuthScheme
INFO: ntlm authentication scheme selected
Jan 10, 2008 3:10:54 PM
org.apache.commons.httpclient.HttpMethodDirector
processWWWAuthChallenge
INFO: Failure authenticating with NTLM <any
realm>@mail.exchangeserver.com:443
I had it working with my internal test server but now when trying
to connect to other servers I am getting Auth issues. Ideas?
Thanks!
Michael
