I just figured this part out.  The radiusd.conf file has an Include
/etc/freeradius/modules statement, and there was a file in the modules
directory called ldap.dpkg-old in that directory that was overiding the
ldap config file.  That doesn't mean everything works, but at least that
mystery is solved.
