[Samba] Samba3 joining W2k3 as member server

[Carlos R. Pena Evertsz]

Hi Pieter,

I need to do the same, join a Ubuntu 12.04 samba server to an existing 
Win2k3.

Could you post an example of the shares configuration (users and group 
read and write permitions) to be used in your example of a samba server 
as a domain member?

Thanks.
