> and/or data integrity protection (which protects the data from 
> tampering). During TLS negotiation the server sends its X.509

> (such as TLS). Though technically the server may use any identity 
> information established at any lower level, typically the server will 
> use the identity information established by TLS.

> default 636. LDAPS differs from LDAP in two ways: 1) upon connect, the 
> client and server establish TLS before any LDAP messages are transferred 
> (without a StartTLS operation) and 2) the LDAPS connection must be 
> closed upon TLS closure.
