The issue of synchronization of authorization flow with work object flow in a document production workflow environment is presented and discussed in this paper. We have shown how a work object flow is synchronized with the authorization flow using a central arbiter in Web service paradigms. The co-ordination of Web services is done using WS-BPEL which supports orchestration and XACML provides authorization for Web services. The synchronization is achieved by exploiting the obligation provisions in XACML.
