Rest Assured - NTLM Authentication

[Sarath Kumar]

Hi!

I'm trying to automate REST API of Microsoft MSD CRM application using Rest Assured and it requires NTLM Authentication. I have used the below line of code for NTLM authentication and getting the error message;

            given().

auth().ntlm("username", "password", Workstation/hostname, "domain").      

         when().

       get("https://request URL'").

   then().

   statusCode(200);

Error: WARNING: NEGOTIATE authentication error: No valid credentials provided (Mechanism level: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt))

Can anyone please help me how to do the NTLM authentication  - OR - if there is any alternate way to negotiate authentication as mentioned in error.

Please share your response immeditely if anyone knows as it's blocked with client deliverables.

Thanks,
Sarath
