Description

The requirement is to have multiple Usergrid systems, each with its own Cassandra cluster, be able to authenticate Admin Users with one central Usergrid system – giving Admin Users Single-Sign-On (SSO) across all of those systems.

We can do this by adding just one new end-point to Usergrid.

This Google Doc explains a complete design for "Usergrid Central SSO":

The design is based on earlier work by Ed Anuff and Nate McCall.
