Doing ntlm authentication to access a .NET Webservice.
Unfortunately I am getting:
Unable to respond to any of these challenges: {negotiate=Negotiate}
When I access the site/uri with the browser (safari) I am getting the
login-Dialog to authenticate and can then access the webservice.
My auth-code looks alike
...
final NTCredentials ntCredentials = new NTCredentials( "<uid>", "<pw>", "",
"<domain>" );
final CredentialsProvider ntCredentialsProvider = new CredentialsProvider()
{
public Credentials getCredentials(final AuthScheme scheme, final String
host, int port, boolean proxy) throws CredentialsNotAvailableException {
return ntCredentials;
}
};
DefaultHttpParams.getDefaultParams().setParameter(
"http.authentication.credential-provider", ntCredentialsProvider );
...
Also trying to force NTML-only (in order to omit negotiation) fails:
...
// force NTLM
DefaultHttpParams.getDefaultParams().setParameter(
"http.protocol.handle-authentication", false );
List<String> authpref = new ArrayList<String>();
authpref.add( AuthPolicy.NTLM );
DefaultHttpParams.getDefaultParams().setParameter(
"http.auth.target-scheme-pref", authpref );
DefaultHttpParams.getDefaultParams().setParameter(
"http.auth.proxy-scheme-pref", authpref );
...
It used to work before the endpoint was moved to another host. There I
would/did see (in the log/console):
- ntlm authentication scheme selected
What can I do to narrow down this problem?
