Hi.

I have a fresh install of DNN 4.8.2

When I instal the AD Provider and try to login from /DesktopModules/AuthenticationServices/ActiveDirectory/WindowsSignin.aspx i see the runtime error. In event viewer it like

8/8/2008 7:32:53 AM   General Exception       AssemblyVersion: 04.08.02; PortalID: 0; PortalNa ...

And I can not login from login page (windows Login).

In IIS WindowsSignin.aspx have only integrated Windows authentication.

Yes. I'm try to uncomment the <identity impersonate="true"/>  tag and adding my username and password.

What kind of authentication must be in the IIS for my site (without WindowsSignin.aspx)?

P.S. Sorry for my english, i'm russian

When I set <customErrors mode="Off" /> I see
