Attributes and Elements

The following sections describe attributes, child elements, and parent elements

Attributes

Attribute	Description
value	The name by which a client uniquely identifies an instance of a service. If you install multiple instances of a service on computers throughout a forest, each instance must have its own SPN. A given service instance can have multiple SPNs if there are multiple names that clients might use for authentication.

Child Elements

None.

Parent Elements

Element	Description
<identity>	Specifies the identity of the service to be authenticated by the client.

Remarks

A secure Windows Communication Foundation (WCF) client that connects to an endpoint with this identity uses the SPN when performing SSPI authentication with the endpoint.
