> I have found when using the org.apache.http.impl.auth.win patch for Kerberos authentication
in our corporate environment the InitializeSecurityContext *pszTargetName parameter must be
set to the service principal name (http://msdn.microsoft.com/en-us/library/windows/desktop/ms721625(v=vs.85).aspx#_security_service_principal_name_gly)
for the Kerberos handshake to succeed. 
> This patch allows the service principal name to be provided to the WindowsNegotiateScheme
constructor via the Factory classes. 
> I am unsure if this is required or correct for NTLM.
> For reference the SPN we use is of the form: HTTP/myserver.mycomp.com@REALM.MYCOMP.COM
> * "myserver.mycomp.com" is the host name of the server we want to connect to
> * "REALM.MYCOMP.COM" is the active directory realm.
