NTLM type1msg not getting expected response

[powercat92]

Hello there. Using Node-SP-Auth, it seems that when I get the response to type1msg, I do not get the 'www-authenticate' hash. The value of that header is simply 'NTLM'. From everything I can determine, the module is submitting the correct headers to my 2013 On-prem SP site (type1msg hash, URL, options all look correct). I have the same site working using httpNTLM module and using that module I do get NTLM [hash] in 'www-authenticate' response. I do not get any errors, the request gets sent, the type1msg response gets returned and it just hangs there.

My primary goal here is to use node-sp-auth for AD login, but since I already have NTLM working I am trying to verify that I have the module configured correctly before working on AD login. Once I have it working with NTLM, I'll be certain that the module is set up and working in my environment.

Any thoughts?
