Adding a scenario with solution for cross-domain login

[fellyph]

Description

The current scenario for the SSO demo uses a third-party cookie to create a session between domains a and c; in this example, when the user has the 3PCD enabled, the session cannot be created. This scenario is a frequently reported issue in the Chrome issue tracker.

A demo using Related Website Sets can be created to demonstrate how to solve this issue to keep a session between cross-domains. For example:

domain-ccc.com

• domain-ddd.com
• domain-eee.com

Once the user is logged in at domain-aaa.com, he/she will have a link to navigate between the other subdomains and keep the session.
