There's no specific error when normal HTTP authentication fails either, since
the error codes are (with some rare exceptions) saved for transfer errors and
as long as the transfer went fine it isn't considered a libcurl error but a
higher level error that should be extracted with curl_easy_getinfo() or
similar.

In this case, I figure you getting a 407 back would be indication enough,
won't it?
