This is fine, if you mean that there is an LDAPS listener on port 636.

This works if you have a valid client certificate, issued by the same CA
that issued the server's certificate. It will only work on a plain LDAP port
if you use the StartTLS request first. It will work on port 636 if that port
has an LDAPS listener.

Generally SASL PLAIN is not supposed to be used with LDAP. Use LDAP simple
bind
instead. SASL PLAIN is turned off by default in slapd.
