Passport Authentication .NET 3.5?

[qwedster]

Guys!

What happened to Passport Authentication .NET Framework 3.5? Then MSDN for .NET Framework 3.5,
http://msdn.microsoft. com/en-us/library/eeyk640h.aspx
describes only about,
Windows Authentication Provider
Forms Authentication Provider

whereas MSDN for .NET Framework 3.0,
http://msdn.microsoft. com/en-us/library/eeyk640h(VS.85) .aspx
describes only about,
Windows Authentication Provider
Forms Authentication Provider
Passport Authentication Provider

Is Passport Authentication Provider a legacy technology?

Please answer.

Yes, it's supposed to be a legacy technology.
Passport is a Centralized Directory of user information that web sites can use, in exchange for a fee, to authenticate users.
But you can download and review the free Microsoft .NET Passport Software Development kit from http://support.microsoft.com/?kbid=816418
