There is no ssl port! SSL (Secure Socket Layer) is a proprietary,
licence based protocol, owned by Netscape? I don't know whether the
IPR of this protocol have been part of the Netscape/AOL deal. OpenLDAP,
and most other network based applications, have implemented Transport
Layer Security (TLS), RFC 2246. As a LPI certified professional you
should be aware of this.
OpenLDAP uses port 639, which has not been assigned by IANA to LDAP(S)
protocol, as TLS-enabled port. Port 389 is still required for the LDAP
extended operation startTLS (RFC-4513).

In my experience, OpenLDAP has no problems listening to port 636 as an
SSL enabled port. TLS (using STARTTLS) runs on 389.
