I'm having a curious problem when using Windows authentication with a web
service. I can successfully retrieve the correct user name. I can also use
code like the following to test if the user in an administrator:
Dim Principal As WindowsPrincipal
Principal = CType(User, WindowsPrincipal)
Return Principal.IsInRole(WindowsBuiltInRole.Administrator)
However, if I use the overloaded IsInRole() method that requires the
string name of the group, it always returns false. For example, neither of
these code statements give me the right answer:
Return Principal.IsInRole("Administrators")
Return Principal.IsInRole("MYCOMPUTER\Administrators")
(Where MYCOMPUTER is the name of my local machine.) Has anyone else
discovered this discrepancy?
