Here's what my Gentoo-default auth-passwdfile.conf.ext says:

passdb {
  driver = passwd-file
  args = scheme=CRYPT username_format=%u /etc/dovecot/users
}
userdb {
  driver = passwd-file
  args = username_format=%u /etc/dovecot/users
}

But I don't have an /etc/dovecot/users file.  I also don't seem to
have any mail user uid lower than 1000, but I do have some users above
1000 which aren't mail users (nobody, etc).

Hello Grant,

So as to avoid any ambiguity, could you post the output of "doveconf
-n"?
