User interface
Log in to GRIDportal
Provide a valid username and password to log into GRIDportal.
NOTE: the login procedure assumes you already have stored your certificate on the server, otherwise you must complete that procedure first.
Design
The user supplies a username/password, which is used to query myProxy for a proxy. Once a proxy is available, the authentication is deemed successful. The proxy is now used to interact with NorduGrid/ARC. The session is managed on GRIDportal rules (default WebKit session timeout is 1h). GRIDportal renews the proxy if necessary (if it were to expire before the session).
