On the server (but would it not be slapd.conf for the server?):
more /etc/openldap/ldap.conf
BASE         dc=home,dc=htt
HOST         127.0.0.1
TIMELIMIT    30
SIZELIMIT    0
TLS_REQCERT  allow

And on the AD (but I don't know what classicupgrade is using):

more /etc/openldap/ldap.conf
#
# LDAP Defaults
#

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

#BASE    dc=example,dc=com
#URI    ldap://ldap.example.com ldap://ldap-master.example.com:666

#SIZELIMIT    12
#TIMELIMIT    15
#DEREF        never

TLS_CACERTDIR    /etc/openldap/certs

# Turning this off breaks GSSAPI used with krb5 when rdns = false
SASL_NOCANON    on
