When I try to open the Active Directory extension configuration page, there's an error in the middle:

Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Authentication.ActiveDirectory.Settings.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

I've tried searching google and the DNN forums, and I see a lot of references to the impersonate=true in web.config.  I've tried to access the page with identity impersonate=true, with and without username/password set, and without identity impersonate=true.  And I've seen a few references to some kind of AD manual; but the links for that manual don't seem to work.

 This is a new portal site that we're hoping to deploy very soon.  We have a number of portals already running on the same db, same server, same IIS app.

So, what can I do to fix this?
