[SOAP Extensibility Samples] The authentication header received from the server was 'Negotiate'

Hi, I need to call a Soap WebService, from the cloud environment to a on-premises machine.

I was able to add the webservice to Outsystems using the following URL format:
http://[username]:[password]@[WebservicePath]?wsdl


When I try to call the webservice, I get the following error:

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

 

If I try with basic authentication, I get the same error, but this time regarding basic authentication.

Has anyone have any idea how can I send the credentials with the request? After researching, it seems I need to change the headers or the authentication type, using the Soap Advanced Extensibility, but I have no idea what is needed.

Has anyone encountered the same issue? Thank you for your help.
