On the client side, simply modify /etc/pam_ldap.conf to include these lines:
pam_check_host_attr yes
pam_filter |(host=client_hostname)(host=*)
NSCD daemon is the culprit. Here's the error when I do id tony:

Still the same outcome. I can ldapsearch, getent, etc. but id cannot show the ldap users.
here's my /etc/ldap.confcat /etc/ldap.conf | grep -v ^# | grep -v ^$

I'll start a reinstall of the other packages instead of libnss-ldap and libpam-ldap.
Thanks for the tips.

$ getent passwd |grep tony
$ getent passwd tony
If the first succeeds (returns a line looking like /etc/passwd), and the
second fails (returns nothing), then you probably have a negative cache from
nscd. Stop nscd, and test again.

In some environments, I do use nss_ldap+nss_db/nss_updatedb+nscd, but one of

the newer options (e.g. sssd) may be a better option.
