CAS allows a virtual organization to express policy regarding resources distributed across a number of sites. A CAS server issues assertions to the virtual organization users, granting them fine-grained access rights to resources. Servers recognize and enforce the assertions. CAS is designed to be extensible to multiple services and is currently supported by the GridFTP server.
