how to force basic scheme authentication using HttpClient 4.0.2
I don't want to authenticate with the proxy using NTLM v2 (because it's not supported).
So is there a way to force basic authentication in 4.0.2?
I'm stuck with the 4.0.2 version because I'm using WebDriver 2.0a6.
For older 3.x HttpClients we could do:
HttpClient client = new HttpClient();
List authPrefs = new ArrayList(2);
authPrefs.add(AuthPolicy.DIGEST);
authPrefs.add(AuthPolicy.BASIC);
// This will exclude the NTLM authentication scheme
client.getParams().setParameter(AuthPolicy.AUTH_SCHEME_PRIORITY, authPrefs);
Am I able to do something similar with 4.0.2?
Thanks,
Nick Mills

I think HC 3.x should behave exactly the same way if the NTLM were
disabled. If the target server sends two challenges NTLM and BASIC back
and NTLM is not supported or disabled, BASIC will be used as a fall
back.
Hope this helps

Thanks Oleg,
Works like a charm. I noticed that if I leave the scheme preferences alone it tries to authenticate with NTLM then falls back to basic anyway. I don't remember HttpClient 3.x doing this, is this new in HttpClient?
cheers,
Nick

Yes, you can
With HttpClient 4.0.x one can override the
AbstractAuthenticationHandler#getAuthPreferences() method in order to
return a different sequence of preferred auth schemes
With HttpClient 4.1-alpha-x one can also use
'http.auth.proxy-scheme-perf' and 'http.auth.target-scheme-perf'
parameters to set a particular sequence of preferred auth schemes for
proxy and target authentication respectively.
Please also note HttpClient 4.1 HEAD (to be released as 4.1-beta1 soon)
fully supports NTLMv1 and NTLMv2 auth schemes out of the box
Hope this help

Yes, you can
With HttpClient 4.0.x one can override the
AbstractAuthenticationHandler#getAuthPreferences() method in order to
return a different sequence of preferred auth schemes
With HttpClient 4.1-alpha-x one can also use
'http.auth.proxy-scheme-perf' and 'http.auth.target-scheme-perf'
parameters to set a particular sequence of preferred auth schemes for
proxy and target authentication respectively.
Please also note HttpClient 4.1 HEAD (to be released as 4.1-beta1 soon)
fully supports NTLMv1 and NTLMv2 auth schemes out of the box
Hope this help

Hey Nick,
This is what I do for the basic authentication for my application. Hope this
helps.
-------------------------
private static void setAuthentication(DefaultHttpClient httpClient,
HttpRequest methodReq, Credentials credentials, AuthScope authScope) {
httpClient.getCredentialsProvider().setCredentials(authScope, credentials);
BasicScheme basicAuth = new BasicScheme();
try {
Header authHeader = basicAuth.authenticate(credentials, methodReq);
methodReq.addHeader(authHeader);
} catch (AuthenticationException e) {
e.printStackTrace();
}
}
