Okay thanks, can I create more than one long term proxy on the RAL myproxy server then (I'd still like to delegate to my UI and I think this still needs the password)? Also, we use several WMS: "https://lcgwms03.gridpp.rl.ac.uk:7443/glite_wms_wmproxy_server" "https://wms01.ific.uv.es:7443/glite_wms_wmproxy_server" "https://wms01.grid.hep.ph.ic.ac.uk:7443/glite_wms_wmproxy_server" "https://wms02.grid.hep.ph.ic.ac.uk:7443/glite_wms_wmproxy_server" How do I find out who trust who?! Cheers Jon
