Logging onto mac workstations using accounts stored on server?

Simple question, with perhaps a not so simple answer.

We have a set of workstations running on panther, and an xserve G5 that acts as a file server. We would like to push "login" accounts to the macs, similar to the manner in which windows domain accounts work (set them up at a centralized location in a domain, add the computer to the domain, log in using your domain account). Is this possible using Panther on the workstations and 10.3 server on the xServe? We would like to control log on accounts from a centralized location.

Thanks in advance for any clues.
