Is it possible to use the Windows 2003 user names instead of pre-Windows 2000 user names in Windows Authentication?

[Brian Desmond [MVP]]

IIS must be making the translation internally from the UPN to the 
sAMAccountName. It's not hard to get the UPN given the WindowsIdentity 
object that you have at hand, and relying on the UPN for the user's true 
name is bad programming practice IMHO.

My recommendation is to search AD for that user's object in the directory 
and retrieve the first and last name properties or whatever else you need in 
your code.
