As you told there is no authorization header in the Raw request of ReadyAPI. However even after selecting Raw tab in the request I am getting same error. Please see attached screen shots of ReadyAPI and SoapUI and let me know your thoughts. Thanks & Regards, Arul ReadyAPI throws 401 unauthorized error when accessing kerberos authenticated wsdl. I have Kerberos authenticated webservice deployed in application server. By following steps in below url I am able to setup Spaui 5.30 version for kerberos testing. However in the same system ReadyAPI is throwing unaauthorized error.
