  • [SharePoint]SharePoint Claim base Authentication的一个比较好的介绍

    User identity in AD DS is based on a user account. For successful authentication, the user provides the account name and proof of knowledge of the password. To determine access to resources, applications might have to query AD DS for account attributes and other information, such as group membership or role on the network. While this works well for Windows environments, it does not scale out to third-party authentication providers and multi-vendor environments that support Internet, partner, or cloud-based computing models.

    With claims-based identities, a user obtains a digitally signed security token from a commonly trusted identity provider. The token contains a set of claims. Each claim represents a specific item of data about a user such as his or her name, group memberships, and role on the network. Claims-based authentication is user authentication that uses claims-based identity technologies and infrastructure. Applications that support claims-based authentication obtain a security token from a user, rather than credentials, and use the information within the claims to determine access to resources. No separate query to a directory service such as AD DS is needed.

    Claims-based authentication in Windows is built on Windows Identity Foundation (WIF), which is a set of .NET Framework classes that is used to implement claims-based identity. Claims-based authentication relies on standards such as WS-Federation, WS-Trust, and protocols such as the Security Assertion Markup Language (SAML).

    简洁的翻译一下:Claim-based 使用的不再是像过去那样用户名和密码一样的东西,而是一个Security token串,这个串种包含用户该有的一些基本信息,这样在登陆的时候,就可以直接获取到这些信息,而不用再次去query AD了
