You can do one of two things here - create certs for ldap to use (zmcreateca, zmcreatecert, zmcertinstall mailbox)

OR

edit /opt/zimbra/bin/ldap, and remove the "ldaps://" specifier, and the last four lines of /opt/zimbra/conf/slapd.conf (start with TLS). (You may need to make that change in /opt/zimbra/openldap/etc/openldap/slapd.conf)
