[ceph-users] How to map 2 different Openstack users belonging to the same project to 2 distinct radosgw users ?

I have a question regarding ceph-openstack integration for object storage. Is there some configuration/hack/workaround that allows to map 2 different users belonging to the same OpenStack project to 2 distinct radosgw users ? I saw this old bug: https://tracker.ceph.com/issues/20570 but it looks like it isn't going to be addressed in the near future Thanks, Massimo
