JMeter NTLM authentication failing

Question

I'm relatively new to JMeter, but I am having a hard time getting an HTTP Sampler to land on a secured webpage. I think it requires NTLM authentication, so I used the HTTP Authorization Manager to pass credentials as specified in the BlazeMeter guide

My Authorization Manager has the following values:

• Base URL: https:// [test site]
• Username: [my user name]
• Password: [my password]
• Domain: Same as base URL
• Mechanism: BASIC_DIGEST

However, I just get a 401 error (see Sampler Message below)

I tried the following, but still get a 401 error. Any suggestions?

• Changing all HTTP Request implementations to HTTPClient4
• Setting httpclient4.auth.preemptive=true in the user.properties
• Enable Use KeepAlive option

As per Windows Authentication with Apache JMeter guide you should replace Domain to not to be your base URL but rather Windows Domain name. As per the referenced guide:

Domain: should be “what you see in Windows Security pop-up” as this is what real browsers do. If you are uncertain you can type a fully qualified domain name into that field.

You can also figure out your domain name by running systeminfo command like:

systeminfo | find "Domain"
