When using LDAP and TLS, the initial (unencrypted) connection is made to port 389 and the SSL connection is negotiated on-the-fly. Logically, the unencrypted connection is made initially, then the client and server start up an SSL handshake if both ends support it. The LDAP-over-SSL (LDAPS) method as been deprecated and the preferred method is LDAP and TLS. The TLS method is no less secure as the only thing that goes over the wire unencrypted is the SSL handshake. Just my $.02 -- Jay Leafey - jay.leafey at mindless.com Memphis, TN
