I haven't checked glibc, but it may not have the functions needed to
find information about the users in it directly.  Try adding
libnss_files.so.2 to the /lib directory and see if that helps.

If not, /var/ftp (for the anonymous FTP chroot) is probably a good
example of a minimal setup to refer to, and it may include something
else you might be missing.
