Given a username and password, how do you impersonate that user elevated?

Question

In Windows Vista and later, LogonUser returns a non-privileged token, even if the user provided is an administrator. Thus, when you impersonate using that token, you are non-elevated. Given a correct username and password for an administrator user, how do you run code that has elevated privileges for that administrator?

Answer 1

I just worked with this example, It actually works fine. I guess if you want to run code in this context you'll have to set the current thread principal by:

Thread.CurrentPrincipal = new System.Security.Principal.WindowsPrincipal(WindowsIdentity.GetCurrent());
