I receive the above error when trying to configure a share using a directory taken from a NFS mount.
The NFS mount is needed because that folder is a QNAP NAS and I will use separately my zentyal server in a virtual environment (this is the de-facto standard for domain servers).
How to solve? The NFS hasn't got the option acl (nor xattr) but it obviously supports it. It's Zentyal that doesn't recognize them as you don't specify them in the fstab (I suspect).
Thank you in advance.
