barbara.gm.86: Thanks for the log. The status code windows is returning in
this case is SEC_E_INTERNAL_ERROR. The documentation for
InitializeSecurityContext gives a pretty vague explanation for this
error: "An error occurred that did not map to an SSPI error code."
http://msdn.microsoft.com/en-us/library/aa375507(v=VS.85).aspx

I would normally guess that this is a problem with your environment, but
your initial bug mentions that other browsers have worked without a hitch.
I'll try to get more information about this error.

esteban.liberty: Thank you for testing and providing debug logs. As we
discussed, with 514.0 this returned an ERR_INVALID_HANDLE, which indicates
a programming error on Chrome's end. I also noticed that your handshake
went through a third round of authentication handshakes, whereas my local
tests have all been with two. I'll see if there are any logic issues in
that case.

Interestingly enough the "About" dialog that checks for updates appear to
work okay (the POST to http://tools.google.com/service/update2), despite
the fact that allow browsing has been broken by this issue. So whatever
the interaction is with the proxy for the update check appears to be
different than regular browsing. That, or it's different because it's a
POST. I see that's using a separate exe, so something has clearly changed
between Chrome itself and the updater app.

Hi

I have the same exact error.
After installing Chrome 6 (6.0.472.53) I use it regularly at home (no
proxy) and in my corporate network (linux SQUID NOT authenticated proxy).

BUT
here in my client's network I cannot use it anymore.
I work with my notebook configured with his own workgroup (OS: Windows 7 32
bit) so I'M NOT attached with the domain of the client.
With previsous versions of chrome (eg 5) I was required to insert the
authentication credentials as soon as I tried to navigate the web; with
Chrome 6.0.472.53 I'm not asked anymore and I get the following error:

Errore 9 (net::ERR_UNEXPECTED): Unknown error.

If I open and internal URL (one listed in proxy exception list), I run it
regularly..

Please help

Paolo


I also ran chrome with logging options ... I attach my log file.

Hi again

update:
yesterday evening I tryed Chrome at home (no corporate firewall) ad I
confirm that it WORKED PERFECTLY.
This morning, back again in my client's corporate network, Chrome still
DOES NOT WORK.

Few minutes ago (16:00 italian time) I updated to Chrome 6.0.472.55
version, hoping it could solve the problem .. NOPE!! Same problem again!!!

I produced the log file again, and it looks more detailed than yesterday,
so I attach it back.

Hope it helps...

Cheers,
Paolo

This is ridiculous. Doesn't someone have a fix? Just when I made the big
step to make Chrome my default browser this bug hits and I'm back to MSIE.
Its likely MSIE 9 will come out before this is fixed judging by the posts
so I will probably never standardize on Chrome. As an architect for a
Fortune 500 company I can see CHrome is not for enterprise use.

@barbara.gm.86
thanx for your answer. Sure, not surprising it was working at home, mine
was just a confirmation that the problem is narrowed to authenticated
corporate proxy (ISA in may case).

Just a question: I cannot find which is the last build you report as
working.
If you could tell me I would really apprecciate :D
Another question: I "debug-log" chrome by simply running it with the
following command line flags: --enable-log --log-level=0
Is this enough? I ask it because I noticed that I have no log if everything
works fine (as it happens when I'm home)

For those of you experiencing problems, could you try a more recent
(pre-canary build) to see if some of the changes resolve your issues?

Retrieve the build from
http://build.chromium.org/buildbot/continuous/win/2010-09-12/59195/chrome-win32.zip

Unzip, and run chrome-win32\chrome.exe locally.

Weeks later, still not working. Incredible. I think it say something
serious about how ready this browser is for more than casual use.

MSIE is still our corporate standard, but I would prefer a webkit browser.
I am not at all impressed by MSIE 9 - mostly the lack of extensions that I
started to rely on in Chrome.

I am personally switching to a Mac today or tomorrow and will consider
Safari.

Side note: the response, or lack thereof, of this case also gives me an
indication of the readiness of Google services in general for the corporate
user. As an architect that makes these decisions for a Fortune 500
company I find this rather ridiculous. Maybe I don't understand the
process happening behind the scenes.

A workaround fix. It looks like it is an authentication issue. If I try
to hit an Intranet site that needs authentication, I get this error in
Chrome. If I go into IE and make this site a trusted site, I get the login
box in Chrome and no error.

@willie55 - I've tried this with no avail. Its not really much of a

There's a lot of understandable frustration here. Unfortunately, many of
the fixes made in trunk of Chromium are unlikely to be merged into Chrome 6
at this point.

To help us fix any outstanding issues with authentication, please use the
canary and/or dev channel and see if you run into any problems.

If you do, there are some concrete ways to help:

- Validate that the proxy/server works on IE or Firefox (many of you have
done this already, so thank you).
- Read
http://dev.chromium.org/developers/design-documents/http-authentication for
more information on command line flags for configuring authentication. For
example, you could try specifying --auth-schemes=digest to validate that
the problem is isolated to Negotiate or NTLM authentication.
- Start up Chrome and open chrome://net-internals. Go through the proxy
or reach the problematic server. Click "dump to text" and copy/paste into
the bug report. Please feel free to remove any private data you do not want
to sure, and you can email me directly at cben...@chromium.org if that is
more comfortable.
- Optionally, enable debug logging using the directions at
http://dev.chromium.org/for-testers/enable-logging and provide the debug
logs.

Many of you have provided useful reports and these have helped us correct
issues that are not triggered in our test environment.

While the 7.0.524.0 build would semi-work in the sense that it prompted me
incessantly for credentials, it appears, for me anyway, that this latest
build of 7.0.529.0, is working correctly for all sites now. Thank you!

7.0.529.0 Canary build partially works. If I set --auth-schemes=basic;
username/password is asked once per browser session and all sites seem to
work fine. However, when I set --auth-schemes=NTLM or Negatite (Digest is
not supported) I get random popups repeatedly asking for username and
passwrd (mostly for all the images on a page). Even entering the username
and password correctly doesn't work and after a few retires, my account is
locked which is quite frustrating.

I think I talked so early.

Build 7.0.530.0 (60017) works partially.
It works fine with the sites I've formerly entered. But still keeps asking
for new web sites. And asks for every image on the page. As as enter my
username and password and click "log in" button in the background I can see
the images loading. Each time I hit "log in" button an image is loaded.
They load one by one.

I saw that there were some changes checked in by cben...@chromium.org
regarding some other Proxy Authentication problems. So, it could be the
right time to see whether the problem has disappeared...
No, 7.0.533.0 (60432) is still broken, and I just managed to lock my
user-account...

This latest version shows an new pattern. Earlier builds displayed several
empty proxy user/pwd dialogs. The 7.0.533.0 (60432) still shows several
proxy user/pwd dialogs but they are sometimes already filled with the right
username (and stars for the password)

Going back to 6.0.492.0 (55845) which is the last build taht works for me…

The latest version shows a different pattern: Earlier builds displayed
several empty proxy user/pwd dialogs. The 7.0.533.0 (60432) still shows
several proxy user/pwd dialogs, but they are sometimes already filled with
my username (and probably my password, because there are a few stars in the
password text-box).

external websites via a proxy that uses NTLM authentication (McAfee SCM for

@lajos.vetek (#125)
I can't see a "failing proxy authentication". I can't see authentication at
all. Chromium doesn't prompt me to insert my username/password.
WHY?

@tratrie (#126)
Maybe I'm wrong, especially for the first times the problem appeared, but
as far I can remember I've never tried to navigate to more than one site.
I've gave up after the first failing attempt. Tomorrow I'll try that with a
new build.

@paolo.franceschini (#128)
You said that you "would swear that it begun NOT WORKING after a reboot due
to a windows update session".
But can this explain why going back to 6.0.440.0 it works again??

What is really sad is that 2 months passed after I filed this bug (and
nearly 4 after the problem appeared) and it seems that no one can fix it.

@barbara.gm.86 (#129)
Same thing here: the authenication dialog does not pop up. But
authentication the against the proxy itself does work. All the webpages I
tried were loading fine.

The fix is also in the latest canary build (7.0.548.0 canary build), but
the latest dev channel build (7.0.544.0 dev) is somewhat older, and so it
is still broken.

The proxy server returns the ffg error (from log file) "HTTP/1.1 407 Proxy
Authentication Required ( The ISA Server requires authorization to fulfill
the request. Access to the Web Proxy filter is denied. )"

A few things to note,
1) I am on a corporate network and I have a normal domain account.
2) Access to the proxy server uses a different set of credentials! i.e. the
credentials used to access/authenticate against the proxy server is
different to the my normal domain credentials.
3) The last working version of Chrome that works
Google Chrome 6.0.437.3 (Official Build 50164)
WebKit 534.1
V8 2.2.17
I get a pop-up box which allows me to enter the user details to
authenticate against the proxy server.
4)I also have Firefox installed. So I am not sure why its also failing to
retrieve the proxy setting from Firefox (which is setup correctly)

Comment #159 on issue 51404 by Anthony....@gmail.com: "Error 9
(net::ERR_UNEXPECTED): Unknown error." / Error 338
(net::ERR_INVALID_AUTH_CREDENTIALS) while behind a proxy
http://code.google.com/p/chromium/issues/detail?id=51404

Error 9 (net::ERR_UNEXPECTED): Unknown error.

Attempting to access a website hosted on an IIS6 server on Windows 2003
with "Integrated Windows Authentication" located in a DMZ.

If I access that website using Chrome 15.0.874.121 m, from another Windows
7 64bit PC that is NOT behind a proxy then it works just fine.

If I access that website using a Windows 7 64bit PC that is behind a ISA
Proxy then it almost always (98%) dies with the above error. Occasionally
it will work or work partially (a partial page will load). This might
happen if I poke at it long enough by flipping between various browsers and
loading up multiple tabs in chrome.

All other browsers (BB, IOS, FF, IE 7,8,9) work just fine.

Proxy auto-configuration (PAC) instructions do not work correctly in Chrome
whilst doing OK in Internet Explorer. Chrome is using "system settings".

if (
(host.substring(0, 4) == '127.') ||
(host.substring(0, 8) == '192.168.')
) {
return 'DIRECT';
}

I can't give much technical information except to say that I'm behind a
Bluecoat corporate proxy and using Chrome version 23.0.1271.97. When
websites are on the "blocked" list to which my Windows user has explicit
access (i.e. Bluecoat needs to know who I am) Chrome fails miserably. IE 9
works fine as does latest build of FF.

I would greatly appreciate some assistance with this as it means I have to
use IETab for those sites or fire up the dreaded IE.

I too have been receiving the Error 338 (net::ERR_INVALID_AUTH_CREDENTIALS)
however I am not behind a proxy. I am attempting to access a website hosted
on an IIS7.5 box with windows authentication enabled. The website should
authenticate without prompting for credentials. This website works
correctly when viewed via Firefox and Internet Explorer 9, and does not
prompt for credentials.

The only solution that I have found to get the site to work with windows
authentication in Chrome is to remove Negotiate from the list of Windows
Authentication providers in IIS7. This leaves only NTLM as the windows
authentication provider in IIS. Since the website works fine in FF and IE9,
I guess this is a bug with Chrome and IIS negotiate windows authentication.
Are there any solutions to this issue other than removing Negotiate as a
provider for windows authentication in IIS?

lmanders2: Can you answer the question from comment #164, as well as
indicate on what platform and Chrome version you're attempting to auth with?

I assume that the question you would like answered is the last question
asked in Comment #164 about having Extended Protection for Integrated
Windows Auth enabled. To answer the question I guess that I do not have
Extended Protection enabled since I do not have the registry keys for
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA\SuppressExtendedProtection
or for
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LmCompatibilityLevel.

I am running Windows 7 64bit and the latest version of Chrome (23.0.1271.97
m)

cbentzel: Is this still relevant, or should it be archived since the NTLM
issues are being investigated in #168034?
