Account stores are used to log on a user with credentials and to extract security claims for the user.

Display name—Provides a space for you to type the friendly name of the AD LDS account store.

URI—Provides a space for you to type the Uniform Resource Identifier (URI) for the AD LDS account store. A URI is a compact string of characters that is used to identify an abstract resource or physical resource. A URI consists of a scheme name, followed by a colon, followed by some scheme-specific data. URLs such as http, ldap, gopher, and ftp are valid URIs, and Uniform Resource Names (URNs) such as urn:fed:companyname are also valid. You can also use your own custom URI format, for example, fed://identity-sts.
