Dorian: Grid Service Infrastructure for Identity Management and Federation

Identity management and federation is becoming an ever present problem in large multi-institutional environments. By their nature, Grids span multiple institutional administration boundaries and aim to provide support for the sharing of applications, data, and computational resources in a collaborative environment. One underlying problem is to enable participating institutions to manage the identities of their own members by leveraging existing institutional identity management systems, while at the same time facilitating the participation in larger Grids through the deployment of grid-wide user credentials. Those grid-wide identities are used for features such as single sign-on, secure communication, and are the basis for authorization decisions. In this paper we will present the design and implementation of Dorian, a grid service infrastructure component that enables the federation of users across the collaboration.
