WCF-BasicHttp and PreAuthenticate RRS feed

  • Question

  • Hi there, 

    I have a basic question : 

    • An ERP exposes a WebService that expects Basic Authentication
    • With SOAP UI when I do preemptive authentication it works, when there is no preemptive authentication it fails.

    So basically the behavior of the WebService is : get the request if there is no authentication information in the header send a soap exception (this is not the standard behavior of returning a 401 and then the caller send the Authentication information on the second call)

    Thanks for any help
