Detect user logged on a computer using ASP.NET app

Question

I want to develop an ASP.NET application that can detect the user logged on a Window Domain. These credentials are going to be used to logging on the ASP.NET application.

How can I do this?

Thanks!

Answer 1

In IIS, turn on Integrated Windows Authentication, and in code, if you use:

Request.ServerVariables["LOGON_USER"]

it will return the windows username of the logged in user, i.e. MYDOMAIN\MYUSERNAME

Answer 2

For ASP.net, you can probably use

HttpContext.Current.User.Identity

If IIS is configured correctly (no anonymous logons, at least)
