SoapUI 4.6.4 - Create project from WSDL under basic auth

hi,

i am unable to load my wsdl in SOAP UI .The web service is hosted on a server with Basic Kerberos authentication:

This is what I have tried so far :
http://www.soapui.org/SOAP-and-WSDL/spn ... ation.html
http://stackoverflow.com/questions/9148 ... entication

the ui prompts for authentication details like DOMAIN\USER , not able to proceed even after giving details.

if i use burp as a proxy im hitting 401 authentication error .

Could someone please help on the kerberos setup for Soap. ive tried with the latest soap 9.5. still no luck.

thanks,
Manushi.
