The maximum number of seconds an authenticated session may last
before termination of the session. A value of zero indicates
that no session timeout will be applied. This value MAY be
superseded by a session timeout value provided by the
authenticating server. For example, if a session is
authenticated by a RADIUS server, that server may encode a
Session-Timeout Attribute in its authentication response. The
operational timeout value of a given authenticated session
is specified by the etsysMultiAuthSessionSessionTimeout object.
