Oddly enough I have two servers set up. One will allow me to automount, the other one won't. Unfortunatley the test server works, while the production one won't. Both are G4's, the only real difference is that the G4 that won't work has 2 Nics, on has 4 ports on it, I don't see this being a hold back.
Good luck to you guys, let me know if you figure anything out, I will continue to play with it. Let me know how things go on your end.
