Share files between RedHat and Mac

view story

http://unix.stackexchange.com – I have one RedHat 6 machine and three Mac OS machines. I want the RedHat one to be a file server, so that all files will be stored there. All Mac clients will access this server according to their rights. It seems that this will not use samba. Could you please let me know what should I do in this case? (HowTos)
