[Samba] A question about samba and quote

[ARPAV\atomelleri in locale]

Hi,

We've a Samba server as purely fileserver in AD windows enviroment with
a 2k3 server as bdc.
Our goal is implement quote to manage disk space usage on samba server.
Is it supported by samba ?! if not, which is the best way to approach it ?
I did a little search on google but I've not found a clear way or
documentation about it, so any advice is really appreciated.

thx in advance, Alessio
