does this email you've pasted not even come with a please or thankyou?

Whoever is doing this is, pardon me, insane. If you want to share files between UNIX machines, you should be using NFS. The excuse of:
is silly. You need to have permissions to do the same thing with other file "sharing" techniques like samba. Just set up an exportfs from the Linux server, and tell all the OS X machines to mount the filesystem via NFS. It's not difficult, and it's a hell of a lot more robust than the SMB garbage being used by samba (remember, samba is designed to interface UNIX and windows because windows doesn't know how to deal with a real network filesystem).
You already have a solution that, "works without error". Use it!
