Fedora directory users - Jan 2008 - "Add machine scripts" for Samba with FDS backend

Does anyone have some "add machine scripts" that they would like to
share?  I am having trouble getting any of the examples I find to
work, I am using FDS 1.1 on Fedora 8 with Samba 3.0.28.  I could use
all the useradd and groupadd scripts as well.  Thanks.
