== Welcome to Hub


Hub is a single sign-on solution for multiple Ruby On Rails applications which
are running under the same domain but different paths within that domain. When
a user signs into Hub, they don't have to individually sign in to other
applications on the domain provided that those applications are integrated
with the Hub mechanism. This requires software development effort on behalf of
the application installer or application developer.

Hub provides a solution to a different problem from that addressed by cross
domain single sign-on solutions such as OpenID, wherein a user will typically
have to sign in to domain individually, but is at least able to do so using a
single set of identifying credentials.
