9. London e-Science Centre 9 myproxy:MyProxyServer: MyProxy server hostname myproxy:ProxyServerDN: Expected MyProxy server distinguished name so GridSAM can authenticate the server. myproxy:ProxyServerPort: MyProxy server port. The default is 7512. myproxy:ProxyServerUserName: The MyProxy username myproxy:ProxyServerPassPhrase: The plain-text MyProxy passphrase. User should authenticate and authorise the GridSAM server before passing this information across the network. myproxy:ProxyServerLifetime: The lifetime of the delegated proxy retrieved from the MyProxy server. myproxy:MyProxyServer: MyProxy server hostname myproxy:ProxyServerDN: Expected MyProxy server distinguished name so GridSAM can authenticate the server. myproxy:ProxyServerPort: MyProxy server port.
