This project authenticates with System.Security.Principal.WindowsIdentity
I had a look at this: Can't get HttpContext.Current.User.Identity to work in my WebMatrix project
IIdentity WinId = HttpContext.Current.User.Identity;//returns no data
WindowsIdentity wi = (WindowsIdentity)WinId;
I have disabled anonymous in my Web.config
<authorization>
<deny users="?" />
</authorization>
The wierd part is I have another project that uses the same code and has has the same .config but works,
