Shibboleth-based federations emerge in numerous countries, especially in the academic sector. Leveraging these federations for authentication and authorization purposes in Grid computing is one aim of current research. In this paper an architecture for delivering attributes managed by both, Shibboleth IdPs and VOMS, to Grid resources for authentication and authorization purposes is presented. Special focus lies on linking web-based Shibboleth federations with the X.509 certificate-based grid security infrastructure by using a short lived certificate service as a trust-proxy between these worlds.
