Hi guys,
to keep you informed.
I got in contact with the WD support, and the issue is still pending. The first attempts by a helpful guy at WD did not solve it, but the case got now forwarded to the technical department for a while now. When they answer, I will report.
To remember:
Access to all share without any password was possible via NFS, but not (correctly) via e.g. SMB.
During my search I found this link - thanks to the original poster:

I connected via SSH (using Terminal on a Mac) and disabled these services permanently from the startup-options of the MyBook:
/etc/init.d/nfs-kernel-server stop
/etc/init.d/nfs-common stop
So there is no NFS support and so no access anymore - at least using this protocoll. SMB still works fine - sufficient for my needs.
While solving this „hole“, the situation stays with the unpleasant feeling that other holes do still exists, without being aware of them.
