How can a service verify the credentials provided by a consumer?
Problem
Some of the capabilities offered by a service may be intended for
specific groups of consumers or may involve the transmission of
sensitive data. Attackers that access this data could use it to
compromise the service or the IT enterprise itself.
Solution
Service capabilities require that consumers provide credentials
that can be authenticated against an identity store.
Application
The service implementation is provided access to an identity
store, allowing it to authenticate the consumer directly.
Impacts
Consumers must provide credentials compatible with the
service's authentication logic. This pattern may lead to multiple
identity stores, resulting in extra governance burden.
