------------------------------------
Attachment: HTTPCLIENT-1540.patch.diff
I've confirmed our company's outbound approval so here's my patch for this
issue.
I'm setting the bit as documented in [Microsoft's
documentation|http://msdn.microsoft.com/en-us/library/windows/desktop/aa375509(v=vs.85).aspx].
> Support delegated credentials (ISC_REQ_DELEGATE) via ClientWinAuth

> If you use this Wikipedia graphic as a reference,
> http://en.wikipedia.org/wiki/Kerberos_(protocol)#mediaviewer/File:Kerberos.svg,
> the current implementation in HttpClient 4.4alpha1 does the first (red) and
> last (green) steps but it doesn't do the middle one (middle). By adding a
> parameter, it won't skip out on the middle step (where the Windows LSA will
> ask the Windows domain controller to generate a ticket-granting-ticket for
> the requested service).
> In {{WindowsNegotiateScheme.getToken()}}, the change would be to update
> {{Sspi.ISC_REQ_CONNECTION}} to {{Sspi.ISC_REQ_CONNECTION |
> Sspi.ISC_REQ_DELEGATE}}.
