DFS Questions

If you install DFS Juncitions to volumes and shares that are on a
cluster do you need to have edirectory installed on each of your nodes
in the cluster?

I have read that Apple File Protocol does not support DFS. I am curious
what will a Apple user then see. For example if I the following
"shared" folder with a DFS junction they could see data at this level
but nothing below this?

server volume folder
server1 soft shared
server2 vol1 marketing
