a) I setup an IIS test installation with the Windows Authentication module
and was able to test the "normal" HTTP authentication with Basic, Digest and
NTLM, and didn't see any problems - without cdccb422671aeb the base64
decoding fails and I get the 401 from the type-2 with NTLM authentication.

b) I setup FreeProxy for Windows so I could test the Proxy Authentication
but unfortunately mostly had success:

NTLM and Basic - worked.
Digest - FreeProxy always seem to respond with a HTTP 200 rather than 407
that I would have expected although I'm not sure I have users,
authentication settings and restriction settings set up correctly for digest

I also tried to creating a Visual Studio Solution to compile the various
parts of the test server: getpart, resolve, sockfilt, etc... and failed
miserable :(

In summary I have no idea why Test 206 is failing at present, so if you
could do some digging Daniel that would be great.

c) On other failures:

Test 220, 221, etc... appear to be failing because of getpart() returns -1.

I suspect this is because the <data base64="yes> tag has the base64 data
spread over many lines. I think this could be reworked so that getpart()
calls appenddata() to append the raw base64 encoded string to the buffer and
then when the end </data> tag is read it calls Curl_base64_decode() rather
than calling it on a line by line basis.

d) On other news:

I had some connection problems when I took my Proxy Server down which I
think could be related to the Happy Eyeball work but I will post this
information in that thread ;-)

Kind Regards
