[Pgi-wg] OGF PGI - Security - Interoperability in progress between EGEE and OSG (using COPS)

[Steven Newhouse]

It is my understanding that this work addresses a very different use case than we have been discussing within PGI. Its a deployment that is encapsulated within the service infrastructure (generally within a single site) to support authorization decisions. Not the user/role driven authentication tokens that we have been discussing within PGI - our primary use case.
