solution myproxy
Solution: “MyProxy”
  • Myproxy allows you to store a long-lived proxy in a “MyProxy repository” and derive a proxy certificate when needed.
  • Allows you to:
    • Interact with a grid from many machines
      • And you realise that you must NOT, EVER leave your certificate where anyone can find and use it.
    • Use a portal, and delegate to the portal the right to act on your behalf (by logging in to an account that can make a proxy certificate for you)
    • Run jobs that might last longer than the lifetime of a short-lived proxy
