Personally, I would find it much more useful to allow using cdbr(3) for
indexed access. Pad the username to the maximum length found and it all
boils down to the user having consistent crypt(3) hash settings. Even
without the latter, you can't distinguish a valid username from an
invalid one, just that you have a set of accounts using shared hash
settings.
