AFP permits Apple MacOSX users to access the storage resources of XigmaNAS.
This is a short description to get the XigmaNAS server act as a Mac-File Server using Netatalk 2.2.4 File Services.
I assume the XigmaNAS server is up and running…
mkdir /mnt/yourvolume/yoursharedfolder
chown macuser:macgroup /mnt/yourvolume/yoursharedfolder
chmod 2775 /mnt/yourvolume/yoursharedfolder
(if you have other users you dont want insider there at all use 2770)
chomd -R 2775 /mnt/yourvolume/yoursharedfolder
and simply dont work on the top-level. this seems to be some umask-mac specific problem
