Installing the Discovery Service
This section describes the Centralized Discovery Service which is primarily aimed at providing a backstop service for Federation and other metadata aggregating and distributing agences. Outside this scope it is very limited. Service Providers are recommended to install the Embedded Discovery Service.
Before You Begin
The first question you should ask is whether you need to install the DiscoveryService. If you're working in a non-Java environment, you may find it easier to build a selection page in a more native fashion. The SP also supports the Embedded Discovery Service which is usually a better choice for SPs which need to implement discovery.
