Hi Nathan,

Indeed that was the reason. With your hint I was able to find the
relevant documentation:

https://docs.ceph.com/docs/master/cephfs/client-auth/

that is completely absent from:

https://docs.ceph.com/docs/master/cephfs/quota/#configuration

I will send a pull request to include the link to client-auth in the
CephFS quota page.

thanks
Mattia
