    the directory the client is restricted too (e.g., ``/home/user``)
    or something nested beneath it.
 
+   In case of a kernel client, it needs to have access to the parent
+   of the directory inode on which quotas are configured in order to
+   enforce them. If quota is configured on a directory path
+   (e.g., ``/home/volumes/group``), the kclient needs to have access
+   to the parent (e.g., ``/home/volumes``).
+
+   An example command to create such an user is as below::
+
+     $ ceph auth get-or-create client.guest mds 'allow r path=/home/volumes, allow rw path=/home/volumes/group' mgr 'allow rw' osd 'allow rw tag cephfs metadata=*' mon 'allow r'
