We recently published new content that describes the People Picker control and its relationship with custom claims providers. People Picker (shown below) is a Web control used to find and select users, groups, and claims and then grant them permissions to items such as lists, libraries, or sites in Microsoft SharePoint Server 2010 and Microsoft SharePoint Foundation 2010.
In order to use People Picker effectively in your site collections, it is important to understand the relationship between People Picker and the authentication method used by the Web application that contains the site collections. The information that People Picker resolves and displays is dependent on whether classic or claims-based authentication is used with the Web application. Before reading the new People Picker content, we recommend that you first read Plan authentication methods.
Also note that there are no Windows PowerShell cmdlets for configuring People Picker. People Picker configuration is performed using properties for the Stsadm setproperty operation, but only when the Web application uses Windows authentication.
The newly published content includes the following articles:
I want to thank Steve Peschka for his invaluable help in writing the custom claims provider content. For more great information about claims and SharePoint, see his blog http://blogs.technet.com/b/speschka/.
