If you're looking for a solution that can keep a little more state you
may be interested in nss-pam-ldapd (shameless plug here). It started out
based on nss_ldap but has a local daemon that connects to the LDAP
server. You can more debug fail-overs (and other things) more easily
because ik can run in debug mode.

You can even use it with the nssov overlay in slapd to provide the local
daemon part and increase the reliability even further (using replication
or caching).

Hope this helps
