The question how to handle authorization of digital identities in a Service-Oriented Architecture (SOA) remains an open issue. In this paper, the authors present a design pattern for the integration of legacy systems with SOA using out-of-the-box (unmodified) application servers and discuss how the architecture has to be extended by an Identity Management (IdM) infrastructure. The authors claim that the IdM infrastructure itself must be designed in a service-oriented way to fit into the overall SOA approach. The authors introduce a possibility how to decouple the policy enforcement point from the application server and propose an architectural design pattern to seamlessly integrate the SOA's business-related functionality and the IdM infrastructure. An implementation case study illustrates how to apply the invocation pattern for secured web services.
