Hy@everybody,

in the last few days I play around with QWebKit (and network). I only wanna do a simple thing: I want do dowload only a simple webpage. My problem is the proxy in our comapny, it requires and authentication. All works well. But I want to setup my program in the way the the user should not setup the proxy himself. I have searched the web for it and find out that (in Windows) the key-technique is SPPI (NTLM) => and here is my problem:How can I tell Qt to use SSPI instead of "handmade" proxy username and password. I only can get the hostname and the port, but the username and password has to be sent from windows (secutiry) itself (using SSPI).

Here is my Testcode (only.cpp):
Qt Code: 
  1. #include "httpui.h"
  2.  
  3. HttpUi::HttpUi(QWidget *parent, Qt::WFlags flags)
  4. 	: QMainWindow(parent, flags)
  5. {
  6. 	ui.setupUi(this);
  7.  
  8. 	nam = new QNetworkAccessManager(this);
  9. 	HideWidgets();
  10. 	connect(ui.getButton,SIGNAL(clicked()),this,SLOT(activateGetWidgets()));
  11. 	connect(ui.submitButton,SIGNAL(clicked()),this,SLOT(DoHttpGet()));
  12. 	connect(ui.resetButton,SIGNAL(clicked()),this,SLOT(clearWidgets()));
  13. 	connect(nam,SIGNAL(finished(QNetworkReply*)),this,SLOT(finished(QNetworkReply*)));
  14. 	connect(ui.postButton,SIGNAL(clicked()),this,SLOT(activatePostWidgets()));
  15.  
  16. 	connect(nam, SIGNAL(proxyAuthenticationRequired(const QNetworkProxy&, QAuthenticator*)), this, SLOT(onProxyAuthenticationRequired(const QNetworkProxy&, QAuthenticator*)));
  17. }
  18.  
  19. HttpUi::~HttpUi()
  20. {
  21.  
  22. }
  23.  
  24. void HttpUi::onProxyAuthenticationRequired(const QNetworkProxy &prox, QAuthenticator *auth)
  25. {
  26. 	auth->setUser("myuser");
  27. 	auth->setPassword("mypassword");
  28. }
  29.  
  30. void HttpUi::changeEvent(QEvent *e)
  31. {
  32. 	QMainWindow::changeEvent(e);
  33. 	switch (e->type()) {
  34. 	case QEvent::LanguageChange:
  35. 		ui.retranslateUi(this);
  36. 		break;
  37. 	default:
  38. 		break;
  39. 	}
  40. }
  41.  
  42. void HttpUi::activateGetWidgets()
  43. {
  44. 	ui.urlLabel->setHidden(false);

  57. 	ui.dataLine->setHidden(false);
  58. 	activateGetWidgets();
  59.  
  60. }
  61.  
  62.  
  63.  
  64. void HttpUi::finished(QNetworkReply *reply)
  65. {
  66. 	if(reply->error() == QNetworkReply::NoError)
  67. 	{
  68. 		ui.textBrowser->setText(reply->readAll());
  69.  
  70. 	}
  71. 	else
  72. 	{
  73. 		ui.textBrowser->setText(reply->errorString());

  85. 	{
  86. 		nam->get(QNetworkRequest(QUrl(url)));
  87. 	}

  89. 	{

  91. 	}
  92.  
  93. }

  124. }

The code is from here. I only add the connect for proxyAuthenticationRequired-SIGNAL => so if a password is required i can set it.
I can't get it work over SPPI because I don't know how to use SSPI in Qt!

So my question is: How can I use SSPI-Authentication instead of setting it myself?

Qt: 4.7.3
OS: Windows 7 x64
