Use Case 4: Extended Networks
In Use Case 4, smcompany.com, ahealthco.com, and discounts.com all participate in an extended federated network. This case is an extension of the use cases presented previously.

In this network, not all customers of ahealthco.com work at smcompany.com, so ahealthco.com provides discounts to its customers by establishing a relationship between themselves and discounts.com. Because ahealthco.com maintains user identities for every customer, it is possible for ahealthco.com to manage local credentials, such as a password for each user. By managing local credentials, ahealthco.com can authenticate users and provide single sign-on access to its partners.
In this extended network, the users access each website differently:
- User1 accesses health benefit information at ahealthco.com website. User1 can access partsco.com website by clicking the PartsSupplier link at smcompany.com, the employee portal. User1 can also click a link at the employee portal to access discounts at discounts.com.
- User2 authenticates at ahealthco.com website and clicks a link to access discounts at discounts.com, without logging in to discounts.com website. The discounts presented to User2 reflect the business arrangement between ahealthco.com and discounts.com. Being employee of smcompany.com, User2 can also click a link at ahealthco.com and access the employee portal at smcompany.com without logging in to smcompany.com website.
- User3 (not shown in example), is a customer of ahealthco.com, but is not an employee of smcompany.com. User3 authenticates at ahealthco.com website and clicks a link to access discounts at discounts.com without logging in to discounts.com website. The discounts presented to User3 reflect the business arrangement between ahealthco.com and discounts.com. Because User3 is not an employee of smcompany.com, User3 cannot access smcompany.com website.
