Samba Team member John Terpstra has a Samba3 article on InformIT. The case study offers an "example of simple Samba network server architecture." Small to mid-sized offices looking to migrate to Samba might be interested in this piece:

The office of Abmas Accounting Inc. is a 40-year-old family-run business. There are nine permanent computer users. The network clients were upgraded two years ago.
