...If you have an AD go for a real business storage product....
So, what's preventing D-Link from including AD integration for the DNS-323?
Samba v3.x (in FWv1.04) already has AD support. Creating a web page option that would
modify the 'smb.conf' to include 'security = domain' and provide the 'net join' utility
to create the secrets.tbd file is all it would take (I believe) to achieve AD integration.
I imagine this enhancement would place a greater burden on you testing and QA procedures,
but AD integration would open up a whole new market for the DNS-323.
