Understanding Single Signon for Unified Navigation

In a PeopleSoft environment, single signon is deployed for a number of reasons. For users, single signon provides the ability for them to navigate freely within a environment of multiple applications after being authenticated only once. For integration of PeopleSoft applications and systems, single signon identifies those systems that are trusted participants in the integration. With unified navigation, single signon is deployed for both purposes: to identify those trusted systems and to allow users to navigate freely to resources on those trusted systems.
