JMeter v. 4 NTLM Authentication

Question

I have an issue with NTLM Authentication, I'm using JMeter v. 4 and this is first time I'm using JMeter, so I'm beginner.

I've tried to follow couple of solutions that I found here but I'm still facing issue.

HTTP Authorization Manager has following values:

Base URL: http:// [test site]
Username: [my user name] - (have even tested with user@domain)
Password: [my password]
Domain: Domain
Realm: Empty - (have even tested with domain.local)
Mechanism: BASIC_DIGEST - (have even tested with KERBEROS)

My HTTP Request has following:
Basic
Server Name or IP: http:// [test site]
Method: GET
Use KeepAlive is enabled
Browser.compatible headers is enabled
Advanced
Implementation: HttpClient4

I have tried to edit \\bin\\user.properties\\ and added Setting httpclient4.auth.preemptive=true or httpclient4.auth.preemptive$Boolean=true but still having issue:

Response message: Unauthorized

Response headers:
HTTP/1.1 401 Unauthorized
Content-Type: text/html
Server: Microsoft-IIS/8.5
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
X-Powered-By: ASP.NET
X-UA-Compatible: IE=Edge
Date: Fri, 02 Mar 2018 08:42:30 GMT
Content-Length: 1293

HTTPSampleResult fields:
ContentType: text/html
DataEncoding: iso-8859-1

The configurations that I have are based on JMeter NTLM authentication failing 1 . Is there any difference between versions? What am I missing? What could be wrong?

Answer 1

1. According to HTTP Specification there could be multiple WWW-Authenticate headers in the server response.
2. According to RFC 2617 the client must choose the strongest option, in your case it is Negotiate which most probably means Kerberos so I would suggest trying out configuring JMeter for Kerberos.
