We've done some work on trying to manage a common authentication system for
Kepler. There is an AuthenticationManager that provides authentication,
certificate management, and session management on behalf of the user. By
using the API that we provide, the AuthenticationManager can store and
authenticate using several different mechanisms that are encapsulated as
AuthenticationService classes, including on service that handles the
generation and use of proxy certificates. When a client like an actor makes
a call to the AuthenticationManager, a UI can be displayed to ask the user
to provide credentials specific to the domain being handled. The API for the
AuthenticationManager and AuthenticationService is described here:
When the API is used, a specific AuthenticationService class is instantiated
based on the domain of the service request. The set of service classes is
determined at run time from a properties file (also described above), so new
AuthenticationService types can be added as needed.
