PrincipalPermis sion.Demand() always fail even user is authenticated?? ?


I have problem with below code:

WindowsPrincipa l principal ;

principal = new WindowsPrincipa l(WindowsIdenti ty.GetCurrent() );

WindowsIdentity identity = (WindowsIdentit y) principal.Ident ity;
PrincipalPermis sion permission = new PrincipalPermis sion(identity.N ame,
null, identity.IsAuth enticated );


permission.Dema nd();

catch(System.Se curity.Security Exception ex)
System.Windows. Forms.MessageBo x.Show(ex.Messa ge);

permission.Dema nd() always throws exception since
identity.isAuth enticated returns true, however, if using the below

PrincipalPermis sion permission = new PrincipalPermis sion(identity.N ame,
null, false );

then it passes the validation, I am really confused,
any one could help please???

I thought the last parameter is just extra check whether current user
is authenticated or not, if we set it to false, then it ignores it.
Maybe I misunderstand it.

Thanks in advance
