shared address book

hi I'm administrating a small Mac network with about 10 clients, and i'm in the progress of porting to Mac OS X. I have the Mac OS X server up and running. (v. 10.2.1) and two os X clients for testing. I would like to create a shared address book, residing on the server, for the clients to access, containing all our customer contacts etc. The clients should be able to add/delete contacts. Can this be done using the system Address Book? if so, how? I have read: https://www.afp548.com/Articles/Jaguar/ldapcontact.html But that is not what I want. The article describes how I can share the emails etc. for the registred users on the network. thanks, (great website, keep it up)
