Can't add user in ASP.NET Web Site Adminstration Tool

I have added the SQL Role Provider and SQL Membership Provider to an existing application and set the authentication mode to W开发者_运维问答indows. I have created roles, but I cannot add users.

In the Security Tab of Web Site Administration Tool, I search for my user name and get the following:

No users found for this search.

It is my expectation that the tool would search AD for users. Am I supposed to add users to the aspnet_Users table manually? Or is there some key configuration element I'm supposed to set in the Web.config?

Here is an article by Scott Gu on how to do what you want.

Forms authentication should be used in order to add users through the WebSite Administration Tool. WHen using Windows authentication new users must be added by creating a new account in ActiveDirectory on the domain.
