Entity Configuration of PID/(Q)EAA Providers

The PID/(Q)EAA Providers, as Federation Entity, are required to adhere to the guidelines outlined in Section Configuration of the Federation. Specifically, they MUST provide a well-known endpoint that hosts their Entity Configuration. The Entity Configuration of PID/(Q)EAA Providers MUST contain the parameters defined in the Sections Entity Configuration Leaves and Intermediates and Entity Configurations Common Parameters.

The PID/(Q)EAA Providers MUST provide the following metadata types:

  • federation_entity

  • oauth_authorization_server

  • openid_credential_issuer

In cases where the (Q)EAA Providers authenticate Users using their Wallet Instance, then the metadata for wallet_relying_party MUST be provided in addition to the metadata above. In case a national eID scheme is used by the PID/(Q)EAA Providers for the User authentication, they MAY include a metadata for openid_relying_party within their Entity Configuration. The openid_relying_party metadata MUST be compliant with the current version of SPID/CIE id OIDC Technical Specification.

Metadata for federation_entity

The federation_entity metadata MUST contain the parameters as defined in Section Metadata of federation_entity Leaves.

Metadata for oauth_authorization_server

authorization_servers

OPTIONAL. Array of strings, where each string is an identifier of the OAuth 2.0 Authorization Server (as defined in [RFC 8414]) the PID/(Q)EAA Provider relies on for authorization. If this parameter is omitted, the entity providing the PID/(Q)EAA Provider is also acting as the Authorization Server.

credential_configurations_supported

JSON object that outlines the details of the Credential supported by the PID/(Q)EAA Provider. It includes a list of name/value pairs, where each name uniquely identifies a specific supported Credential. This identifier is utilized to inform the Wallet Instance which Credential can be provided by the PID/(Q)EAA Provider. The associated value within the object MUST contain metadata specific to that Credential, as defined following. See OpenID4VCI Sections 11.2.3 and A.3.2.
