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.
