* UNIX extension are smb1 only and are only implemented by the Samba
  server (not windows).
* POSIX extensions are for smb2+ and are still experimental.

The fact that serverino gets disabled looks like a bug. As Steve said,
the problem seems to be related to ACL.

You should open a bug and provide dmesg and network capture as
documented here:
