[OpenSTA-users] OpenSTA on Clustered Environment with Kerberos

[Gary C. <gar...@gm...>]

Hello.

We use OpenSTA v 1.4.4.
We have 2 test environments:
1. Non-clustered, and using NTLM
2. Clustered, and using Kerberos (Negotiate) - where load testing will
be conducted
All web servers are Windows 2003 Server.

In the non-clustered env, we could record successfully. We need to
manually edit the script, though, for the NTLM change-response
authentication. But the script works, no problem with that. However,
in a non-clustered env, we get the 401 Unauthorized status most of the
time during the recording of the scripts. And afterwards, we would
also be getting this when we access the web app using just the browser
(without OpenSTA recording). After leaving the machine idle for a few
minutes, it returns back to normal.

We could actually record successfully sometimes. But most of the time,
it's unsuccessful. Nevertheless, a complete script usually gets the
Unauthorized status when ran. So we can't proceed with our load
testing because we're not sure if the error is caused by incorrect
scripting or by OpenSTA itself.

Does any of you know why this happens? Is this because of the
clustering or the Kerberos? Or both?

Regards,
