Subject JMeter multiple NTLM authentication
Date Thu, 31 Mar 2011 19:34:49 GMT
I'm using JMeter 2.4 on Windows to test an II6 site which only supports NTLM
and Negotiation authentication.

NTLM authentication is working using the HTTP Authorization Manager, but
JMeter pre-emptively tries Basic Authentication on each request.  This
results in 3 attempts for every request whereas a browser would normally
only go through this process once per connection.

This puts an additional load on the web server and the Active Directory
domain controller which makes the test results less accurate than they
should be.

Is it possible for JMeter to pre-emptively send the NTLM challenge response
on subsequent requests once the initial authentication has completed?
