##### To Configure a Service Description

The Service Description attribute defines a running web service at a distinct protocol endpoint. It is defined when you configure Resource Offerings for Bootstrapping. Information about service instances needs to be communicated in various contexts. For example, the Discovery Service defined is an identity service which provides an enumeration of resource offerings (each of which includes a service instance description).

1. Click Add Description to display the new service description attributes or click Edit to modify an existing description.
2. Provide values for the attributes based on the following information:
   Security Mechanism ID

     This attribute is where authentication methods supported by the Discovery Service are added. These security mechanisms refer to the way a web service consumer authenticates to the web service provider or provides message-level security. By default, all available methods that the service instance supports are selected. If an authentication method is not selected, and a web services consumer sends a request using that method, the request is rejected. See Supported Authentication Mechanisms.

   End Point URL

     The value of this attribute is the URL of the SOAP-over-HTTP endpoint. The URI scheme must be HTTP or HTTPS as in `https://soap.profile-provider.com/soap`.

   SOAP Action

     The value of this optional attribute is the equivalent of the `wsdlsoap:soapAction` attribute of the `wsdlsoap:operation` element in the service's concrete WSDL-based description.

3. Click OK to complete the service configuration.
4. Click Save on the Discovery Service page to complete the service configuration.
