As no delegation takes place, the legal entity fulfilling the Entitled Party-role also fulfils the Service Consumer-role.
Note that an Identity Broker can be introduced to broker the relation between the Service Provider and the Identity Provider(s). This is optional and useful in situations with several Identity Providers.
It is prerequisite of this use case that:
The Service Provider has and manages its own entitlement information indicating what Entitled Parties are entitled to what (parts of) services*;
The Service Consumer has and manages its own authorization information indicating which Human Service Consumers are authorized to act on its behalf**;
The Service Consumer registers the authorization information at the Identity Provider;
The Human Service Consumer is able to authenticate the Service Provider;
The Service Provider is able to authenticate the Human Service Consumer;
The Identity Provider is able to authenticate the Service Provider;
The Service Provider is able to authenticate the Identity Provider;
The Human Service Consumer has been issued identity credentials by the Identity Provider.
In this use case the Entitled Party is also the Service Consumer.
*The Service Provider can outsource this function to a third party
**The Service Consumer can outsource this function to a third party
The use case consists of the following steps:
The Human Service Consumer requests a service from the Service Provider;
The Service Provider asks the Human Service Consumer to select his Identity Provider;
The Service Provider requests a login from the Identity Provider;
The Identity Provider authenticates the Human Service Consumer;
The Identity Provider issues an identity assertion and authorization assertion to the Service Provider;
The Service Provider validates the identity assertion and authorization assertion through the following steps:

The Service Provider authorizes the Human Service Consumer of the Service Consumer based on the authorization assertion and the entitlement information registered with the Service Provider;
The Service Provider executes the requested service;
