NTLM proxy doesn't work (and, I suspect kerberos proxy)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start Browswer behind NTLM proxy such as Network Appliance NetCache proxy
2. No web-page loads (www.google.com) (e.g. browser no workie)
3. There is no step 3.

What is the expected output? What do you see instead?

I expect to see a web-page.

What version of the product are you using? On what operating system?

Latest 5-22-2008 snapshot.  Windows Vista, Windows XP SP1

Please provide any additional information below.

I think this has to do with the fact that QAuthenticator doesn't support
multi-challenge responses.  See documentation inside qauthenticator.cpp
[C:\Qt\4.4.0\src\network\kernel]:

    /*
      Fun from the HTTP 1.1 specs, that we currently ignore:

      User agents are advised to take special care in parsing the WWW-
      Authenticate field value as it might contain more than one challenge,
      or if more than one WWW-Authenticate header field is provided, the
      contents of a challenge itself can contain a comma-separated list of
      authentication parameters.
    */

Just to confirm: Did you have this problem with Qt 4.4.0?

I can confirm proxy issues, too, with the snapshot from 5/28/08. Not sure if 
it's the
same problem, but I use an identical proxy configuration in Firefox.

I also have a problem with proxy with qt 4.4.0
We already talked about it on irc.

I looked at the tcpdump, and the problem is that qt does request but does not 
send authentification.

This is an issue with Qt and not Arora so I am close/moving it.

On NTLM: Testing against squid it does work, Qt's isn't perfect and because 
NTLM is a
closed spec support for it will improve when the Qt devs have time or are paid 
by a
customer to support box X, or get patches.

Qt does have authentication support and Arora hooks into that (tested against 
squid).

There is an open Qt task for kerberos/ntlm here:

Hello. I know this post is closed/moved since Jun 2008.
I just read it, and this post aplies to my problem. I am trying to implement 
Arora in
the institution I work for, but no lucky because NTLM dont work with Arora + 
ISA.
Firefox has addicional configuration options, where you can include some 
options to
make it working. I rather be using Arora, cause its very light and fast, and 
also
works with Citrix (thats a must for me).
Don't think we should depend only on QT. Unless we really have to admit that 
Arora
Browser don't work with ISA and there is nothing to be done about it.
Should I drop Arora until QT make that work?

Thank you for reading.

Looks like someone outside of Trolltech will have to make a patch to Qt if they 
want this feature.
