Hi!

Is using windows auth an exceptable workaround? Turning off anonymous and turning on windows does make ria service work under UWS. We are still working on the issue.

Requiring windows authentication is not going to really be workable for us. Our product already requires non-windows credentials (we talk to a legacy app) to log in so "logging in" twice with windows and then proprietary credentials would confuse our users.

Surprisingly few customers have had a problem with installing IIS, mostly since MS has linked IIS to the "professional" versions of its OS and also linked joining a domain to the "professional" version or higher. This means we have not run into many customers using a "home" version of the OS. Our main problem with IIS is that sometimes local IT has locked it down in weird ways or added group policies which effect it in weird ways. So the main benefit of using UWS would be cut down our support costs by a) the client does not have to figure out how to install IIS and b) offer a quick alternative when when IIS was setup in some way that causes problems for our app. Making them log in twice would negate those support savings.

Thank you much for the details.

We most certainly are going to try to fix this problem in the next release. But while you use existing build, using Windows authentication in the Intranet/inside-the-LAN setting could be a temporary fix. With modern browsers Integrated Windows authentication (NTLM/Kerberos) does not pop up prompts for username/password if server and client are on the same or related domain - browsers just pass current client user token.

Sorry it's taking a while. We have contacted Microsoft RIA folks and gearing up for RIA code tracing. We should have more information in a couple of days.

Hi,

Microsoft RIA Services people investigated and were able to reproduce the problem. They said that authorization fails in WCF pipeline, before control reaches RIA. We have forwarded this issue to WCF folks, and will keep you posted regarding the progress.

Hi there!

It took us a few attempts to solve this, including protracted and largely futile dialog with Microsoft, but we can offer a simple work-around: please set <authentication mode="None" /> in the <system.web> section of the web.config (see attached), if you use Anonymous auth in your application's UWS authentication settings. In order to continue using Windows auth (default in web.config) in your app, please select "negotiate" or NTLM auth option in UWS application settings and clear Anonymous checkbox.

We are working on making Windows auth in UWS behave in a way that is more consistent with how IIS does it. Hopefully next build (16) will have solution that will let you keep default web.config auth settings (Windows) and combine it with "Anonymous" auth in UWS.

Best regards,
UltiDev Team.
