GT4 Delegation Service Factsheet

1. Brief component overview

The Delegation Service is a new component in Globus Toolkit 4.0. This component provides an interface for delegation of credentials to a hosting environment. This enables a single delegated credential to be shared across multiple invocations of services on that hosting environment (e.g. it could be used for multiple GRAM job submissions or across GRAM and RFT submissions.)
