The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'default'.'

Question

I am writing API automation via. MStest framework. The wsdl I am trying to automate takes Kerberos authentication. Even though I have provided client_Id, client_secret and user/pass authentication I am still getting 401 unauthorized error. As I am new to this, I might be asking something silly here but I didn't get any answer anywhere so far.

Exception : "The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'default'."

Inner Exception: "The remote server returned an error: (401) Unauthorized."

You can try to set the security mode in the config:

<security mode="TransportCredentialOnly">
  <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" />
  <message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
