[Qt-interest] NTLMv1 HttpProxy in QT 4.5.3

[Сергей Н]

Yes, i have SSL libraries on the machine.
Problem happens not only when i try to connect via https, but even if
i'm connecting via http (through http proxy with ntlm auth).

I made a test for http connection through http proxy with ntlm auth.
I installed new Windows7 OS on my machine.
Visual Studio 2008 Team + SP1.
QT 4.7.1 - ftp://ftp.trolltech.com/qt/source/qt-win-opensource-4.7.1-vs2008.exe

on the server 3proxy is installed http://www.3proxy.ru/?l=EN
config:
---------------------------
#!/usr/local/bin/3proxy

nserver xxx.xxx.xxx.xxx

nscache 65536

users sh0375:CL:123

log d:\logs\3proxy.log D

auth strong
allow sh0375
proxy -p4777 -a

auth strong
flush
maxconn 32
socks -p4778
---------------------------------------

I open http QT example.
D:\Qt\4.7.1\examples\network\http

add these lines to httpwindow.cpp:

HttpWindow::HttpWindow(QWidget *parent)
    : QDialog(parent)
{
	QNetworkProxy proxy(QNetworkProxy::HttpProxy);
	proxy.setHostName("xxx.xxx.xxx.xxx");
	proxy.setPort(4777);
	proxy.setUser("sh0375");
	proxy.setPassword("123");
	qnam.setProxy(proxy);

launch example and try to download url http://qt.nokia.com/

receive the error:
---------------------------
HTTP
---------------------------
Download failed: Proxy requires authentication.
---------------------------
OK
---------------------------

If i turn off NTLM authorization on proxy server - add -n option -
everything is working well
proxy -p4777 -n -a

Is it bug of QT?
