People Picker and claims provider planning (SharePoint Server 2010)
Published: February 3, 2011
People Picker is a Web control used to find and select users, groups, and claims to grant permission to items such as lists, libraries, or sites in Microsoft SharePoint Server 2010. When a Web application uses claims authentication mode, the People Picker control uses a claims provider to list, resolve, search, and determine the "friendly" display of users, groups, and claims. A claims provider in SharePoint Server 2010 issues claims, which SharePoint Server 2010 then packages into security tokens for users. Although People Picker is used by site, list, and library owners to assign permissions to sites and content in SharePoint Server 2010, its behavior is heavily dependent on how authentication has been configured for the whole Web application. It is important to plan for People Picker and claims providers when you plan authentication methods for your SharePoint Server 2010 solution.
