Does anyone have any code to query active directory via an ASP classic application. Basically, I want the application to verify that the user is logged into the network, and simply return the username they are using. This is done on a single signon network, so there is no interaction with the end user.

if you were using .NET 2.0 and Visual Studio 2005 you could generate a managed class from the Active Directory WMI provider to easily access the AD schema.
