Call Web Service located on site with Negotiate provider


Badge +3

Hello! I'm trying to use Call web service action in my worklow to request data from web service, which is located on IIS web site with the following list of auth providers:

And I'm always getting 401 unauthorized error when just trying to get the list of available methods:

   205903_pastedImage_2.png

I remember, that i faced this issue before, with different serversitewebservice and fixed that by leaving only NTLM in list of providers. But now I can't do that, since we need Negotiate (and Kerberos) by design )

As I understand, it just can't negotiate Kerberos and fallback to NLTM, simply giving me "Unauthorized".

Any ideas are welcome!

What response to you get from a browser when trying to get to the wsdl?

If you use POSTMAN chrome extension, can you perform a get with the same credentials?

Heh, in browser I've got triple loginpassword request, then 401.5 error.

So, I think, I'll go to webservice owner to fix this ) Thank you!

Anyway, can Nintex perform fallback to NTLM in case of Negotiate doesn't work, who knows?
