I read all docs from FreeNAS, Openfiler, NASLite, Darma a.s.o.
The main thing that I see about them is that they are small embedded OS-es (mainly based on xNIX flavours). They have cute web interfaces but Slackware can do also do all that stuff.
What I'm asking is how do I map a samba share (or some other kind of share) onto the Windows server in such a way that Windows manages access rights and quota? The server is an AD, so I cannot let linux manage users and such (anxiously waiting for Samba 4

)
