using client application services with windows authentication - where are my roles? Hi, I am trying to use client application services. This is a new feature of .NET3.5 to leverage the ASP.NET provider model to winforms. I am using the sample application that can be found on http://aspalliance.com/1596_Client_Application_Services__Part_2.all. All the examples that I can find use the membership provider and the role provider together. However in my situation I have to use windows authentication instead of the membership provider and I want to combine that with a custom sql role provider and profile provider. I added a user to the aspnetdb database in the sample application with the same name (domain\username) as the windows login name. I then set the authentication in the sample winforms project to windows but I leave the role provider pointing to the website. Now I can log in using windows (leaving username and password blank) but the role provider can no longer find my roles even though there is a user in the database with the exact same name as the windows login. Does anyone know if there is a solution for this problem? Thanks, Martin.
