ah ha! That did it! Digging through their scripts, I notice the
requirement you mentioned where it needs the nis libraries. This is
something that was missed in ALL the other chroot "tutorials" I've
read.

I copied over the nis_nss.so.1 and nis_files.so.1 and now it works!
Turns out they are required user passwd lookups.

Thanks much! My problem is now solved.
