Question regarding NTLM
Hello everybody,
This is my first message here.
I am load testing an IIS application which using NTLM to authenticate.
I am using the latest - 2.5 JMeter and trying to use the HTTP Authorization
Manager.
Firstly - it seems like only with HttpClient3.1 Implemented HTTP Request the
NTLM string is being sent (I can see it on the view results tree for the
relevant request).
When using the new HttpClient4 or the old Jave implementation - this NTLM
Authorization string is not being sent or not being visible on the view
results tree.
Secondly - I configure as best as I understand the Base URL, the Username
and Password, also tried to play with the Realm and Domain but I keep on
getting 401 error.
I tried different combination like username = domain\uname, uname@domain,
uname and on Realm and Domain separately and so on.
Is there someone who actually succeed on authenticate with IIS NTLM ?
Best Regards,
Shmuel Krakower.

And even if the proxy did support mulitple users, the load test would
test the proxy+server.
If there are performance problems it could be difficult to determine
if the proxy is to blame rather than the server.

I only see " The code was refactored to facilitate future support of
multiple profiles and other planned extensions." - not that it actually
supports , and their config doesnt seem to indicate otherwise. Without
multiple users there isn't really a load test.

According to their web page they added multiple user support back in 2007.
It would hardly be an optimal solution, but might work as a stopgap measure
until something else could be figured out. If I had a choice between that
and not testing, I'd be willing to give it a shot. My methods tend to be a
bit... unorthodox... though.

There's an open source NTLM proxy, cntlm, which might let you work around
it. It wasn't terribly difficult to configure when I looked at it. Works on
UNIX too. If you're really hard up...

The HC4 sampler in JMeter might well need tweaking to work properly
with NTLM; patches welcome (via Bugzilla).
It's rather difficult to test the NTLM implementation - as far as I
know there are no publicly accessible servers which support NTLM
authentication.
If you know of one - or even a semi-public one that could be used by
selected developers only - please let us know.
As far as I know, the Java implementation only supports NTLM on Windows.
I don't know if it supports anything other than NTLMv1.
The HC3 implementation only supports NTLMv1

hi
seems there are some issues with HttpClient4 and NTLM
http://hc.apache.org/httpcomponents-client-ga/ntlm.html.
You might give the sample code a try and see if it works (standalone) , and
if it does you might need to modify the Jmeter code to work with HttpClient4
