[keycloak-dev] Initial Client Storage SPI

[Francis Pouatcha]

PSD2 does not define any client registration process. But after reading the
last release of the RTS (Regulatory Technical Standard), we have the
following plan for a reference implementation:

1- Certificate based Dynamic Client Registration
The EBA (European Banking Association) requires each TPP (Thirs Party
Provider) to have a digital certificate issued by their country authority.
Based on the RTS (Regulatory Technical Standard) released so far, the flow
we are modelling plans some sort of Certificate Based Dynamic Client
registration.

2- Activity and Fraud Reporting
PSD2 requires ASPSP (Account Servicing Payment Service Provider) to report
irregular activity on a regular basis. Many banks will extend existing
fraud reporting systems to fulfill this requirement. Most of these system
will store more information on the client than required by the identity
provider.

3- Managing the Client Life Cycle
For same reasons (like fraud management), managing the life cycle of TPPs
(Keycloack Clients, including temporary suspensions) shall be delegated to
the PSD2 specific backend.

4- Adding TPP Specific Information to the Access Token
I hope the "Client Attributes Map" will help pass over some client specific
information to the OIDCProtocoMapper so we can add this to the access token.
