JAAS Shared State

The JAAS shared state enable sharing of both user ID and password between authentication module instances. Options are defined for each authentication module type by realm, user, service and role.

If an authentication fails with the credentials from the shared state, the authentication module restarts the authentication process by prompting for its required credentials. If it fails again, the module is marked failed. After a commit, an abort, or a logout, the shared state will be cleared.
