Yes. Please check out


Only difference in the config for you is that you will exclude following 
two lines

                identity = "uid=onex,cn=users,dc=cs,dc=school,dc=edu"
                password = "oursecret"


ldap ldap_1x {
                server = "ldap1.cs.school.edu"
                basedn = "dc=cs,dc=school,dc=edu"

                base_filter = "(objectclass=radiusprofile)"
                start_tls = yes
                # This is your Certificate Authority (CA) certificate
                tls_cacertfile = /etc/ldap/csca.crt
                tls_require_cert = "demand"
                access_attr = "radiusFilterId"
                dictionary_mapping = ${raddbdir}/ldap.attrmap
                authtype = ldap

                ldap_connections_number = 5
                timeout = 4
                timelimit = 3
                net_timeout = 1

Hope this helps,
