[openstack-dev] Replication multi cloud

Hi Chmouel,

using this approach should I need to have the same users in both keystone?

Is there any way to map user A from cloud X to user B in cloud Y?

Our clouds have different users and replicates the keystone could have
some problems, not only technical.

Cheers,
Marco
