You can require TLS (SSL) via the slapd.conf(5) security directive.
The client can then either use ldap:// (to whatever port(s) you have
configured slapd(8) to listen on) and initiate TLS via
the Start TLS operation or use ldaps:// (to whatever port(s)
you have configured slapd(8) on) and initiate TLS upon
connecting. If you want to restrict clients to using just the
former or the latter, eliminate one or the other listener.

While ldap:// uses 389 by default and ldaps:// uses 636 by default,
one can actually use ldap:// or ldaps:// on any port.

ldap:// on port 389 and use of Start TLS operation to initiate
TLS (SSL) is the standard way of securing LDAP with TLS.
