This is the pam config from libpam-ldap, not libpam-ldapd (at least not
0.8.4). If you have ldap as primary you need to disable shadow lookups
to ldap in /etc/nsswitch.conf.
I can't find an upgrade scenario that would leave your config like this.
Did you have libpam-ldap installed before? Can you check if
dpkg-reconfig libpam-ldapd changes /etc/pam.d/common-account and what
the contents of /usr/share/pam-configs/ldap is?

The host=10.x.x.x lookup is just the reverse hostname lookup that sshd
does on every connection (it doesn't have anything to do with
pam_authz_search). sshd doesn't ask for authentication (I'm assuming you
do key-based authentication here) and skips authorisation (account)
altogether.
If changing /etc/nsswitch.conf or fixing your PAM stack doesn't help,
can you send output of nslcd -d without nscd (or unscd) running?
