In the ABFAB architecture, by its very nature users are active participants in the sharing of their identifiers, as they initiate the communications exchange every time they wish to access a server. They are, however, not involved in the control of information related to them that is transmitted from the IdP to the RP for authorization purposes; rather, this is under the control of policy on the IdP. Due to the nature of the AAA communication flows, with the current ABFAB architecture there is no place for a process of gaining user consent for the information to be released from the IdP to the RP.
