Hi,
I am trying configure openldap work with tls , but I have two question about this, first when I use tls openldap use port 389 and ssl port 639 , is this correct ? Second How I can test connection between client and server, cryptography is working ?
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).
# getent services ldaps ldaps 636/tcp
In my experience, OpenLDAP has no problems listening to port 636 as an SSL enabled port. TLS (using STARTTLS) runs on 389.
