Hi,
Trying stuff out. I have this code at startup:

GenericIdentity g = new GenericIdentity("Viv");
GenericPrincipal p = new GenericPrincipal(g,new string[]{"Admin","Backup"});
Thread.CurrentPrincipal = p;                                                  
// System.AppDomain.CurrentDomain.SetThreadPrincipal(p);  //Works

then later (in a different form)

System.Security.Principal.IPrincipal g = System.Threading.Thread.CurrentPrincipal;

but g.Identity at this point is an empty,unauthenticated instance (as it is before setting the Thread.CurrentPrincipal). If I use the CurrentDomain.SetThreadPrincipal version above instead then g.Identity is as expected. AFAICS this is still the same thread so why the difference?

TIA,
Viv
