Thank you, I already switched to NethServer. Rock solid based on Centos with Samba4 included.Easy to configure as domain member and not Domain Controller. FreeNAS was also a great product but not for me. The reason is that FreeNAS need at least 8GB ram because of ZFS structure, so the support team of FreeNAS told me to switch to something for a simple share and so I ended up with NethServer
