c# - A GINA replacement in a .NET language?

I have searched quite a lot of places and I only found one GINA replacement called pGINA but it is in C++ which I don't know at all.

Does anybody know one in either C# or VB.NET?

(I'm writing software for use at work to control what employees are doing)

See Question&Answers more detail:os

Hosting .NET in Winlogon (where GINA dlls are loaded) is probably not such a hot idea- could cause all sorts of conflicts if something else decides to do the same thing, and if you trash winlogon, you're not getting anywhere with that PC. Also, GINA has been replaced as of Vista with ICredentialProvider (see here)- so your investment would be lost as soon as you move to a newer OS. Even there, the same thing applies: custom credential providers are loaded into Winlogon, so probably not a great idea to use .NET there.

Regardless, both of these are intended to support custom authentication modules, not "controlling what employees are doing". There are other ways to run software on the logon desktops, if that's what you're trying to do.

All that said, if you still want to try it, you'll need an unmanaged shim DLL, C++/CLI or some IL hacking (see here) to export the GINA functions because C# can't directly export DLL functions. A pure managed C# solution isn't possible.
