jean-marc, i can't run your example...

I've some problems with my JAVA_HOME in C.\Programs Files (path with space):
Exception in thread "main" java.lang.NoClassDefFoundError: Files\Java\jre1/6/0_04\jre\lib\security\cacerts

Now i haven't the time to change the example...

edit :) ok I set my JAVA HOME to C:\Progra~1\Java\jre1.6.0_04\ and the examples runs ok ;)

It seems we are using NTLMv1: artifactory 2.0.6 uses httpclient 3.x lib which implements NTLMv1. This works fine and authentication is successful. So not (yet) a NTLMv2 issue for me.

Anyway maven 2.2.0 cannot access internet because of Authorization failed: Not authorized by proxy.

I have used the patched lib provided by Konstantin at http://issues.apache.org/jira/browse/HTTPCLIENT-579. You can downloaded it at http://issues.apache.org/jira/secure/attachment/12410908/NTLMV21.RAR 

Then I have rewritten his example see my attached file. Simply drop it to the example dir build and run.

Edit:
Steps to run the example:
1) go to src directory and typ:
$ant
2) go to examples dir
3) edit run.bat and put quotes around the %JAVA_HOME% if it contains spaces
4) edit the java file and put your information (proxy address, login password etc)
5) to compile type
$ ant
6) execute run.bat

Marco could you try the example to see if this works for you?

Marco, I don't know what that means. I am not an expert in this domain. I am just looking for solutions.

Are you sure to have provided all the required information? Do you use my example [1] or the one bundled in [2]?

Proxy authentication is just used in my example.

As far as my interpretation of the JCIF developers' position goes it sounds perfectly reasonable for them to discontinue development of components they consider out of scope and concentrate their efforts on the core competency, which is the NTLM authentication protocol.

> What sould we do?

General recommendation to all HttpClient users is to not use NTLM

That is no acceptable! We work in companies where they impose proxies that use such authentication scheme. We have no influence at all on this choice.

I would really be sorry to be obliged to drop maven because of connection issues that seem not impossible to fix...

> General recommendation to all HttpClient users is to not use NTLM

That is no acceptable! We work in companies where they impose proxies that use such authentication scheme. We have no influence at all on this choice.

I would really be sorry to be obliged to drop maven because of connection issues that seem not impossible to fix... Maven 2.1.0 works fine though...

John Casey commented on MNG-4228:
---------------------------------

Please rest assured that we're not simply going to drop support for users behind NTLM proxies. Our hands are somewhat tied with httpclient, it seems, but we're thinking about using a delegator Wagon implementation for Maven 2.2.1 that would allow you to specify which http wagon impl you want to use...the lightweight-http wagon used in Maven < 2.2.0, which supports NTLM but falls down in other fringe use cases, or the httpclient-driven wagon used in Maven 2.2.0. We're probably going to leave httpclient in as the default choice, but allow users to flip this if they run into problems.

    Resolution: Fixed

lightweight wagon is once again the default for http/s wagons, but httpclient-driven wagons can be selected using:

{noformat}
-Dmaven.wagon.provider.http=httpclient

-OR-

-Dmaven.wagon.provider.https=httpclient
{noformat}

Or, you can configure the provider per-server using the following <server> configuration:

{noformat}
<wagonProvider>httpclient</wagonProvider>
{noformat}

Jean-Marc Borer commented on MNG-4228:
--------------------------------------

So if I understand well:

lightweight wagon is based on Sun's Java implementation and http wagon  is based on Apache's HttpClient lib, right?

Anyway Artifactory (http://www.jfrog.org/products.php) uses plain vanilla httpclient lib version 3 and is able to access the internet through our NTLM corporate proxy. Why is then wagon no able to do that? I was able my self to build a small example with httpclient 3 that works fine...

Great that at least the previous behavior of maven is restored. When is 2.2.1 planned to be released?

@Jean-Marc

There are several versions of the NTLM authentication scheme [1]. HttpClient 3.x _partially_ supports only what is known as NTLMv1. Depending on the version of the ISA proxy and its configuration this may or may not be sufficient.

@Oleg

I totally agree with you, but:
1) httpclient 3.x works for me out of the box with my proxy
2) maven 2.2.0 fails where maven 2.1.0 succeeds to access the web

So I am wondering what is wrong anyway with the lib that wagon uses in maven 2.2.0 since httpclient 3.x works with my proxy? Something is "wronger" than just using another lib...
