Delegation of authority (DOA) is an essential procedure in every modern business. This chapter enumerates the requirements for a delegation of authority web service that allows users and services to delegate to other users and services authority to access computer based resources. The various models and architecture that can support a DOA web service are described. A key component of the DOA service is the organisation’s delegation policy which provides the rules for who is allowed to delegate what to whom, and which needs to be enforced by the DOA service. The essential elements of such a delegation policy are outlined. The chapter then describes a practical DOA web service that has been built and piloted in various grid applications. It concludes by reviewing some related research and highlighting where future research is still required.
