The way it works here (openldap on Linux - RHEL AS4) is that nss_ldap will first
attempt to bind using the binddn specified in /etc/ldap.conf. This requires it
be able to read /etc/ldap.secret. If it is unable to do this it will attempt an
anonymous bind. In either case the bind must have read access to sufficient
information to satisfy the request. I'm not exactly sure what attributes
check_local_user requires to satisfy its requirements that a user is actually local.

FreeBSD may, of course, be different from Linux in this respect. How, if
nss_ldap is failing to bind, does normal authentication work for you?
