is an arrangement
that can be made among multiple enterprises that lets subscribers use the same
identification data to obtain access to the networks of all enterprises in the
group. The use of such a system is sometimes called identity federation.

standard that allows a user to log on once for affiliated but separate Web
sites or networks.
