Apparently both smb and nfs access are provided to the shares. As was
suggested in another response adding the user and password of the client
system to the NAS allowed access. Also it was suggested that ssh access
had been noted elsewhere. The web page for the NAS provides a check box
to enable ssh access with a disclaimer about any changes voiding the
warranty. To be explored.

See: https://community.wd.com/t/mounting-mycloud-ex2-on-a-linux-desktop/98215
was able to mount the NAS using nfsv4.  

See the client parts of https://fedoraproject.org/wiki/User:Renich/HowTo/NFS
and https://access.redhat.com/solutions/3773891 and leave the server config alone
for now.  The first thing to check is the NFS version support.  On the client run:

# rpcinfo -p <NAS-ip> 

You may need id mapping if user and group ID's differ (to check, use "id username").
