Consider the problems of linking together networks controlled by different administrations, and allowing these administrations to maintain autonomy but to use each others services. Consider also what happens if these administrations have different policies on how access should be controlled and security maintained.
We present a model for access control which has been developed to cope with these situations. The model allows administrations to control their own services and users from an "Authority". Services rely on their local authority to control access correctly, and Authorities can exchange information about users and services by the use of a controlled trust mechanism.
