network users without OS X Server

Is it possible to set up networked users without having OS X server? From Directory Access Help: [quote:818c15a247]Shared domains generally reside on Mac OS X Servers because servers are equipped with the tools, such as Workgroup Manager and Server Settings, that facilitate managing network resources and network users.[/quote:818c15a247] This seems to suggest it can be done, but I can find no help on how to do it. thanks in advance
