asp.net - Windows authentication - testing for different users -

There is no role in my application, however I use Windows authentication to prevent anonymous users from accessing webpages. I need to test different users who use the system. I do not want to know different user passwords and I can not set dummy users in Active Directory. So how can I do this?

Set up virtual server with Active Directory Domain Services and IIS. After creating your own domain for your test and creating your own dummy user there, you can test your app using different ASP.NET applications and your app, but it is complete with your Live Active Directory setup. Like will be sandboxed.
