Middleware: Strategies for Directory Deployment--Centralized, Distributed, Federated, and Decentralized

Time 10/14/03 01:15PM-02:30PM

Session Abstract

State university systems (and in some contexts other closely affiliated higher ed institutions) aim to provide integrated services to students and a unified interface to external constituents. Middleware architecture supporting these aims may be crudely characterized as centralized, distributed, federated, or decentralized. Each alternative exacerbates some policy and turf issues among units providing source data and services. The proposed session aims to elucidate the consequences of alternative choices by describing alternative implementations and the unique issues or problems each has faced. The University of Alaska is implementing a distributed directory structure; the University System of Maryland is planning a more decentralized infrastructure. Other university systems will be asked to participate. The UA architecture includes both comprehensive central registry and directory of people at all 15 campuses, and tools to facilitate ownership and update of some attributes (e.g., local email) by campus IT organizations through the registry. Such tools also preserve some local campus-specific policy setting for people affiliated primarily with that campus. Policy and practical issues that have been negotiated among the campuses include conventions for names and public identifiers, unique ids, directory schema, and processes for protecting privacy
