NTLM Authentication with JMeter is receiving a SocketException

Question

I'm trying to load test a SSO request with JMeter (version 2.13). I followed this tutorial and set up an HTTP Authorization Manager with Username, Password, Domain and Mechanism = BASIC_DIGEST.

When I set the proxy server settings of my HTTP Request to Server Name or IP = 127.0.0.1 and Port Number = 8888, I can see my request go through fiddler where it gets two 401 responses and then succeeds. This shows up in the JMeter View Results Tree as a single successful request. However, when I remove the proxy server settings, the request fails and I get the following response:

java.net.SocketException: Connection reset

The log viewer also says this:

org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl$6: I/O exception (java.net.SocketException) caught when connecting to the target host: Connection reset

I have been trying all sorts of things to get this working without the proxy settings including using the HttpClient4 implementation, setting the following in user.properties

hc.parameters.file=hc.parameters

and the following in httpclient.parameters

http.protocol.reject-relative-redirect$Boolean=true

I will also note that when I run the test through Fiddler, I get a prompt asking if I want to ignore remote certificate errors

Session #106: The remote server (server name here) presented a certificate that did not validate, due to RemoteCertificateChainErrors.
0 - Unknown error.

I am assuming this won't make any difference in JMeter as I read that JMeter HTTP samplers are configured to accept all certificates.

Any help getting this up and running (without Fiddler) would be much appreciated.

The problem was that the Secure Credential Store I was trying to connect to required TLS version 1.0. I had to tell JMeter to use this by updating the jmeter.properties file with:

https.default.protocol=TLS
https.socket.protocols=TLSv1
