Federation transactions occur between multiple parties that are often controlled by multiple entities, and different stages of the federation transaction can lead to situations in which a subscriber would need to seek redress from the other parties.

As the recipient of a subscriber’s identity attributes, the RP is the subscriber’s primary view into the federated system. In some instances, the subscriber may be unaware that an IdP is involved with their use of the RP. Therefore, it falls to the RP to provide the subscriber with a clear and accessible method of contacting the RP to request redress. For matters that involve the RP subscriber account (including any attributes stored in the account), RP functionality, bound authenticators, RP allowlists, and other items under the RP’s control, the RP SHALL provide a clear and accessible means of redress to the subscriber. For matters that involve the IdP or CSP, the RP SHALL provide the subscriber with a means of initiating the redress process with the IdP or CSP, as appropriate.

For matters that involve the use of the subscriber account in federation transactions, including attribute values and derived attribute values made available over federation transactions, IdP functionality, holder-of-key authenticators, IdP allowlists, and other items in the IdP’s control, the IdP SHALL provide a clear and accessible means of redress to the subscriber. For matters that also involve a particular RP, the IdP SHALL provide the subscriber with a means of initiating the redress process with the RP. For matters that involve a subscriber account that has been made available to the IdP, the IdP SHALL provide the subscriber with a means of initiating the redress process with the CSP.

For matters that involve the subscriber account, including identity attributes and authenticators in the subscriber account, the CSP SHALL provide the subscriber with a clear and accessible means of redress.

See Sec. 3.6 of [SP800-63] for more requirements on providing redress.
