Is there a way to "link" windows authentication mode with a membership provider?

Question

Edit:

I think I can boil it down to: I want to use windows authentication mode, but be able to get a list of users like you would with Membership.GetAllUsers().

---

I'm trying to develop a solution for use on an intranet, so all the users will be authenticated. I guess I'm looking for a best of both worlds solution.

Here's the gist (I'll edit later for clarification)

• I want to use Windows authentication mode. But then Membership.GetUser() is null.
• I need a consistent foreign key in my data to reference the authenticated user. Also I need to have the users email address for notifications; Windows auth doesn't provide this.
• Any queries to ActiveDirectory will require impersonation of the WindowsIdentity. IT won't provide a "system" account for this use.

Are there any such examples or solutions which fit my needs?

Answer 1

When using Windows Authentication, System.Web.HttpContext.Current.User.Identity.Name will give you the user's name. As for the email address, are you using Exchange?
