"VOMS for GridPP and the NGS"

Dr Mike Jones, Dr Alessandra Forti and Dr Sergey Dolgobrodov, University of

Friday, 13th October 2006, 1400-1500 (UTC+1)

Room 1.10, Kilburn Building

An overview of the Virtual Organisation Membership Service and how it is being
deployed for GridPP and the National Grid Service.

We describe our experience in practical deployment of the gLite VOMS (Virtual
Organisation Management Service). The formation of all sizes of groups with
similar research agenda can be viewed as the emergence of Virtual Organisations
(VOs). The deployment of centralised VOMS servers at a national level as part
of a grid infrastructure facilitates the creation of these groups and their
subsequent registration to the existing grid infrastructures. It also helps
grid resources to engage user communities by dealing with them in a more
scalable way.

In this seminar we will lead in with an introduction to current authentication
and authorisation methods in use within existing grids and being developed for
grids. Continuing on through the emergence of relevant technologies, which try
to embrace the concept of virtual organisations, we will arrive at the VOMS.

We will describe our use cases, some of the technical aspects, and our
experiences of deployment and administration of such a VOMS. We aim to
highlight the impact, both the benefits and the costs, of adopting these
