Grid single sign-on in CCLRC

This paper presents the latest results in on-going work on developing a single sign-on solution to access Grid resources. Since last year's e-Science All Hands Meeting, we have adapted a Java terminal by integrating it with site authentication infrastructures to provide access to the NGS and CCLRC's SCARF cluster, using MyProxy to manage the certificates and proxies that are essential for Grid access. We describe the architecture and details of the implementation, and how it fits into the site infrastructure, as well as future Shibboleth deployments. Although the work is done at CCLRC, this work is applicable to any site with a Kerberos or Active Directory infrastructure, and will be of interest to anyone working with authentication technologies.
