NTLM Authorization does not work with SOAPUI Opensource

Hi all,

Similar questions have been posted about this.  I have a web service that supports multiple authentication methods.  But I want to pass an NTLM authorization from SoapUI.  Unfortunately, the web service first attempts a Kerberos authentication, and that fails.  So the web service goes into "Negotiate" mode - it returns a message:

HTTP/1.1 401 Unauthorized
Content-Length: 0
Server: Microsoft-HTTPAPI/2.0
WWW-Authenticate: Negotiate

It is expecting the request to re-send the authentication, at which time it will then attempt an NTLM authentication.

When testing SoapUI, I struggled with this before I knew the reason, and I tried SoapUI Pro, which does not have this same problem.  SoapUI Pro will authenticate properly

Does anyone know if there is a setting or other workaround in SoapUI OpenSource?

Thanks,

Ron
