I was setting up LDAP Client on a FreeBSD 11.0-RELEASE-p1 fresh installation. I followed the setup instructions from https://www.freebsd.org/doc/en/articles/ldap-auth/article.html0 Section 3.2 mentions that "The net/nss_ldap port uses the same configuration file as security/pam_ldap, and should not need any extra parameters once it is installed." However, in my setup, I found out that I need to copy /usr/local/etc/ldap.conf to /usr/local/etc/nss_ldap.conf
