I just added a reply in Bugzilla to your report of this.
Here, I can get nscd to work with "host: files ldap dns", but I had to restart it after I changed nsswitch.conf.
Ok: I finally got it (hopefully):
I missed that some libldap does a reverse lookup on the ip number in ldap.conf (or the like).
So I need to add the ldap-server in /etc/hosts avoiding the endless loop (and nscd so ping will not stop in futex).
