You can't use netgroups with FreeBSD/ldap, only passwd and group
databases can be used with ldap AFAIK.

If your users have "objectClass: account" there is an attribute "host"
that can be used for limiting access to certain machines. You need the
entry "pam_check_host_attr yes" in your ldap.conf for pam and perhaps
some modifications of the files in /etc/pam.d.

I have never used or tested this but it is a standard feature of
pam-ldap and I guess it should work.
