Etienne raises a valid point...
Important is that old versions of GSI, which do NOT accept RFC-3820- compliant X509 proxies, block interoperability, and are then STRONGLY DEPRECATED.
These are still being used and supported (to provide legacy compatibility) but alongside support for the newer X509 proxy system.
Therefore, each provider of grid middleware using such an old version of GSI : - MUST establish and publish the list of the components which still uses it, - SHOULD migrate to a new version of GSI which also accepts RFC-3820- compliant X509 proxies.
This group has no right to mandate what middleware providers should or should not do! But if no provider is JUST using old versions of GSI and intend to migrate away from them I see no point in trying to define a profile around something that has no clear specification (just the GT implementation) and everyone intends to remove in the future. Surely its better to focus our energies on defining a profile around the new style proxies that groups intend to support going forward? Steven
