The EGEE PORTAL working group aims to propose "best-practice" rules for the access of portals to the grid. By
access to the grid, we mean that the portal should be able to store data and run job on the grid by delegation
of real users, or by itself with its own credentials. To do so, a portal responsible should be able to get a server
certificate for his portal from the EUGridPMA CAs, and then to be able to register this portal certificate to a VO
allowed on the grid. Once the portal have been accepted into the concerned VO, it should be able to store and
access data inside the VO area, and also to run job on site accepting this VO. The usage of these grid
resources by the portal can be done by delegation of a grid- and VO-registered user, or as a resource provider
for an user not registered in the grid.
