Introduction
For users who want to deploy and experience the Notes federated login (federate login), the first thing to know and understand is that the Notes federated login is actually through SAML (Security Assertion Markup Language, assertion Markup Language) to complete the single sign on feature, if the user is also able to understand the "federated identity", will have a great help in configuring a Notes Fe
globally, when accessing another service provider, the service provider that is accessed first interacts directly with the identity provider to ask if the user is globally logged on, and if the user is determined to be globally logged in, allows the user to access the services he or she provides, otherwise redirects the user to the identity provider. For a global login.In a specific single sign-on implementation, the identity provider and service provider interact in different ways. If Microsof

The client uses the certificate key to sign the message to the RP. The RP must be able to decrypt the proof key in the SAML token or reject the message. If the proof key in the token matches the signature in the

The above section describes the failure of Microsoft's passport and traditional SSO in the software architecture. Both of them need to store the user name and password in one place, so no one is willing to, unless one side is particularly strong, otherwise, neither Google nor Baidu is willing to compromise.
So how can we solve the storage problem of this user credential?

The latest Code released by Microsoft is Geneva Beta 1, and the previous code is Zermatt.

WIF (Windows identity Foundation) is a framework for building identity applications. The framework abstracts the Ws-trust and ws-federation protocols, and renders the APIs for building security token services and declarative-aware applications to developers. Applications can use WIF to handle tokens issued by the security token service and make decisions based on identities in Web applications or Web services.
WIF has the following main features:
