The UBIK Session Authentication Management (USAM) is a mechanism for managing all connected users logged in to one or more UBIK databases. There are three general modes of session authentication:
Single Local Authentication
This means that no explicit authorization mechanism is used. The user's session is a single session which cannot be terminated by another user or the system itself.
LAS (Local Authentication Service)
When a local authentication is used, the session management and the data share the same database. This does not mean that a local authentication service has to share a location for the data webservice, only the database connection for both the data service and the session management service have to use the same database connection.
GAS (Global Authentication Service)
Global session management means that the session management is managing connections to one or more databases via a separate databse used to manage these sessions.
