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 <a href="https://www.blazemeter.com/blog/windows-authentication-apache-jmeter" rel="nofollow">BlazeMeter guide</a>

My Authorization Manager has the following values:

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

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

Thread Name: Thread Group 1-1 Sample Start: 2018-02-21 15:55:18 PST Load time: 26 Connect Time: 0 Latency: 26 Size in bytes: 1602 Sent bytes:229 Headers size in bytes: 309 Body size in bytes: 1293 Sample Count: 1 Error Count: 1 Data type ("text"|"bin"|""): text Response code: 401 Response message: 401 Response headers: HTTP/1.1 401 401 Content-Type: text/html Content-Language: en Server: Microsoft-IIS/7.5 WWW-Authenticate: Negotiate WWW-Authenticate: NTLM WWW-Authenticate: Basic realm="BasicSecurityFilterProvider" X-Powered-By: ASP.NET Date: Wed, 21 Feb 2018 23:55:18 GMT Connection: close Content-Length: 1293 HTTPSampleResult fields: ContentType: text/html DataEncoding: iso-8859-1

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

<ul><li>Changing all HTTP Request implementations to HTTPClient4</li> <li>Setting httpclient4.auth.preemptive=true in the user.properties</li> <li>Enable Use KeepAlive option </li> </ul>

As per <a href="https://www.blazemeter.com/blog/windows-authentication-apache-jmeter" rel="nofollow">Windows Authentication with Apache JMeter</a> guide you should replace Domain to not to be your base URL but rather Windows Domain name. As per the referenced guide:

<blockquote>

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 <a href="https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-xp/bb491007(v=technet.10)" rel="nofollow">systeminfo</a> command like:

systeminfo | find "Domain"
