Hi Kennon,

Thanks for you quick update!
I am sorry to inform you that we current don’t support the window NTLM and Negotiate provided in your service.
If you service supports Basic Authentication, you can work around the issue using the following code:
coderObject    luo_base64
luo_base64 = Create coderObject
lb_data = Blob(ls_user+":"+ls_pwd, EncodingUTF8!)
ls_Basic = luo_base64.base64encode( lb_data)
lnv_restclient.setrequestheader( 'Authorization', 'Basic ' + ls_Basic  )
Anyway, thanks for reporting this problem and for your valuable suggestion.
We'll record it as a new requirement/enhancement request.
We'll transfer it to our product team for consideration.

Mark Lee,
OAuth does not help, we are using Windows authentication.

Hi Kennon,

I am sorry to inform you that at least there is no such plan in PB 2018. 
As to whether there will be such plan in the future, it depends on the results of a follow-up analysis from our product team. 

BTW, PB R3 now supports OAuth 2.0. Hope it is useful for you. See link below:

Is it planned?

Hi Kennon,

I’ve checked with our developers; The current RESTClient doesn’t have this feature.

Here is a simple test case: Instantiate the object, then call restclient_test(..) or httpclient_test(..), passing a URL to a webservice running on IIS with IWA (Integrated Windows Authentication) activated.
In our case this is Microsoft Dynamics running on our intranet.

Hi Kennon,

PowerBuilder 2017 R3 now includes the OAuth2.0 functionalities. Is this what you are looking for? If so, you may find more info here:

If not, can you share with us a simple reproducible test case? That way we can better understand the problem.

Using RESTClient object, issuing a Retrieve(...) fails when service host is using Windows authentication.
