> Validate External Token for Usergrid Central SSO
> ------------------------------------------------
>
> Key: USERGRID-567
> URL: https://issues.apache.org/jira/browse/USERGRID-567
> Project: Usergrid
> Issue Type: Story
> Reporter: David Johnson
> Assignee: David Johnson
>
> 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":
> https://docs.google.com/document/d/12kXgaYcB6L9JoTyRGn0ZHEMg3vL1LJDqvtnltIBDa1Y/edit?usp=sharing
> The design is based on earlier work by Ed Anuff and Nate McCall.
