Hi, Norbert,

I am not quite sure what GlobusProxy does. But if you have the DOEGrids 
certificate, you can generate your proxy by using "grid-proxy-init" or 
MyProxy. You can run your workflow based on that proxy till your proxy 

The Kepler authentication framework can help you get the proxy directly. 
You don't even need a certificate installed on you machine. Basically you 
just need an account and password. The authentication framework will 
generate the proxy based on your certificate stored on the GAMA server.

I doubt DOEGrids uses GAMA server as its front. So Kepler authentication 
framework may not help in your case.

Another benefit for using Kepler authentication framework is that it is 
designed (though current GAMA server does not support) to automatically 
renew your proxy so you don't need to re-login after each 12 hours 
(default expire time for a proxy) when you execute a long-running 

Please let me know if DOEGrids does use GAMA server. I will be happy to 
integrate DOEGrids into our authentication framework.
