Using a Grid Certificate

The preferred method for obtaining Proxy Certificates is to use the MyProxy server at NCSA, described here.

Creating the Proxy Certificate: Every Time

Now log in to the machine with your grid certificate. Make sure the Globus tools are in the path, and enter the following:

userjd@some:~> grid-proxy-init
Your identity: [...]
Enter GRID pass phrase for this identity:
Creating proxy ............................. Done
Your proxy is valid until: [...]

Enter the 12+ character passphrase you chose when creating the cert, and you should be good to connect to XSEDE sites without further passwords for the duration of the proxy.

Managing Certificates

Proxy certificates are usually valid for 12 hours. If you finish early, it is a good practice to remove the proxy certificate using grid-proxy-destroy. To check a proxy certificate, use grid-proxy-info, or to check a grid certificate, use grid-cert-info. In general, myproxy-* commands communicate with the myproxy server, grid-proxy-* commands deal with your proxy certificate, and grid-cert-* commands deal with your local grid certificate (when using the MyProxy method, you do not need a grid certificate).
