Hi All, Following ops meeting, I've updated the doc to show that more than just the CEs/SEs need to be updated prior to any change to any UI. https://www.gridpp.ac.uk/wiki/Adoption_of_Backup_GridPP_Voms_Servers#Adoption_of_Backup_GridPP_Voms_Servers As Ewan said, for this to work, any grid systems that read/use proxies/credentials should be updated prior to any UI (that creates proxies/credentials). I'll go through this myself soon, time permitting etc. etc. In the meantime, Kashif, can you opine on whether this list of "proxy readers" is correct (or are there more out there)? * CE * SE * WN (???) * ARGUS (or equivalent credential servers) Cheers, Steve -- Steve Jones [log in to unmask] System Administrator office: 220 High Energy Physics Division tel (int): 42334 Oliver Lodge Laboratory tel (ext): +44 (0)151 794 2334 University of Liverpool http://www.liv.ac.uk/physics/hep/
