I installed a VDT 1.3.9 client at AFS: VDT_LOCATION = /afs/slac/package/globustools/vdtclient/vdt1.3.9 This includes globus tools clients, voms proxy tool and DRM 1.2.9, etc. For Atlas to test DRM, the configuration file to use by drm commands is $VDT_LOCATION/drm/conf/drm.rc. There are many other tech info in this configuration file. Wei Yang | [log in to unmask] | 650-926-3338(O)
