Is there an easy way to auto enable eDirectory users for LUM?

I have configured a SAMBA server on OES2 using NSS. I want to put all user
home directories on a NSS volume so they can either be accessed via NCP or
via Windows domain logon. I am able to make everything work, but I have to
keep manually adding Samba users using iManager.

I was under the impression that if I LUM enable a group in eDir, that when I
add users to that group, that they would be able to access the Samba server
