On a Ceph Monitor:
# ceph auth get client.openstack | grep caps
exported keyring for client.openstack
	caps mon = "allow r"
	caps osd = "allow class-read object_prefix rbd_children, allow rwx 
pool=ssdvolumes, allow rxw pool=ssdvolumes-13, allow rwx 
pool=sasvolumes-13, allow rwx pool=sasvolumes, allow rwx pool=vms, allow 
rwx pool=images"
#


On the problematic Openstack cluster:
$ ceph auth get client.openstack --id openstack | grep caps
Error EACCES: access denied
$


When I change "caps: [mon] allow r" to "caps: [mon] allow *" the problem 
disappears.
