The '''U'''BIK '''S'''ession '''A'''uthentication '''M'''anagement (USAM) is a mechanism for managing all connected users logged in to one or more {{UBIK}} databases. There are three modes of session authentication: Single Local Application, '''L'''ocal '''A'''pplication '''S'''ervice (LAS) and '''G'''lobal '''A'''pplication '''S'''ervice (GAS).
== Single Local Application ==
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. See how to [[HowTo:Configure Single Local Application Authentication|configure authentication using Single Local Application]].

== GAS (Global Application Service) ==
GAS means the session management is managing connections for one or more databases via a separate database used to manage these sessions. A client has to be configured to use the session management service address for athentication and to use a different data service address. See how to [[HowTo:Configure GAS Authentication|configure authentication using GAS]].
