It will be easy as soon as we switch to VOMS. Currently we have several people who are members in multiple VOs. They have a different certificate for each membership and register with the VOs with different certs. You have to contact your CA and explain why you need multiple certs. markus -----Original Message----- From: LHC Computer Grid - Rollout on behalf of Gergely Debreczeni Sent: Fri 1/7/2005 3:20 PM To: [log in to unmask] Cc: Subject: [LCG-ROLLOUT] multiple VO membership Dear * As far as I know, it is not possible in the current releases.
