##### To Configure a Site Identifier

This attribute defines any site hosted by the server on which OpenSSO is installed. A default value and an automatically generated Site ID are defined for the host during installation. Multiple entries are possible. For example, load balancing or multiple instances of OpenSSO sharing the same Directory Server would all need to be defined. The starting point is the Site Identifiers attribute on the SAML screen under the Federation interface. Site IDs are defined in the Servers and Sites configuration screen. For more information, see Servers and Sites.

1. Click New to add a new site identifier or click on the name of a configured site identifier to modify its profile.

   The Site Identifier attributes are displayed.

2. Provide values for the Site Identifier attributes based on the following information:
   Instance ID

     The value of this property is protocol `://`host`:` port.

     If configuring SAML for SSL (in both the source and destination site), ensure that the protocol defined here is `https//`.

   Site ID

     The site ID is an identifier generated for each site (although the value will be the same for multiple servers behind a load balancer). There is a class in the `com.sun.identity.saml.common` package that can be used to generate this identifier manually, if needed. Type the following at the command line:

         % java -classpath FM-classpath com.sun.identity.saml.common.SAMLSiteID protocol://host:port

   Issuer Name

     The default value of this property is host `:`port, but it could be any URI.

3. Click OK to complete the Site Identifier configuration.
4. Click Save on the Local Site Properties page to complete the SAML configuration.
