I would like to create a proxy for the Migdal group, with production role. I would like to use this to then register the Migdal files on PPD dCache with the GridPP instance at Imperial. How would I go about creating the Dirac proxy for this? I tried something along the following lines but it did not work. Migdal is not a VO on its own, but is a group within the gridpp VO. dirac-proxy-init -g gridpp.migdal_user -M gridpp:/gridpp/migdal/Role=production -U I am obviously trying to replicate the following voms-proxy-init command within the Dirac environment voms-proxy-init --voms gridpp:/gridpp/migdal/Role=production --valid 168:0 Any help on this would be wonderful! Thanks and Cheers, Raja.
