Ok, I guess my previous post was a bit winded, and I got no response. No big
deal. I was able to get my application working using HC 4.3 for NTLMv2
authentication. I used your ClientPreemptiveDigestAuthentication class as a
guide, and replaced all DigestScheme stuff with NTLM scheme stuff. I attach my
code that is a slight variant of the Digest class. You may add this to your
examples package if you wish.
I do see one issue you may want to address. This call in the code below (line
44): entity.getContentLength() always returns -1 for me.
The entity does unpack properly containing my SOAP response, even though
getContentLength does not tell me the size of the payload.
Of secondary importance, the symmetry is missing for the NTLMScheme class. You
cannot instantiate an NTLMScheme object like you can a DigestScheme object, you
need to go directly to an AuthScheme through the NTLMSchmeFactory. And the
NTLMSchemeFactory does not have a getNTLMScheme method, just a method that
returns an AuthScheme object. I don't see any way of actually handling an
NTLMScheme object. Or perhaps you meant to hide the DigestScheme object behind
a factory? I suppose not a big deal, but maybe something you want to consider.
