Mark,
Thank you for steering me in the right direction! After fixing the bad
key in /var/lib/ceph/bootstrap-mgr/ceph.keyring at what will be the
mgr hosts, I updated the caps and then was able to deploy mgr
successfully. Curiously, `ceph -s` shows only one of the three mgr
deployed as running.
History follows for deploying mgr to 3 hosts.

Ahhh - probably my fault that, sorry.
Where I have:
$ sudo ceph auth get-or-create client.bootstrap-mgr mon 'allow profile
bootstrap-mgr'
I should have:
$ sudo ceph auth get-or-create client.bootstrap-mgr mon 'allow profile
bootstrap-mgr' > /var/lib/ceph/bootstrap-mgr/ceph.keyring
or something similar - i.e better fix up that file to match the
new key!
Cheers
