TLS, SSL, and data privacy

Both HTTP and LDAP can use Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to secure authentication credentials and data sent over a network.

Both TLS and SSL are supported. Any time an application server has been configured to support TLS, it has also thereby been enabled for SSL 3.0. Whether it actually uses SSL or TLS depends on the runtime negotiation between client and server.
TLS or SSL can be used to verify the identity of one or both of the parties engaged in a network connection.
TLS or SSL can also provide data integrity (proof that the data has not been modified since the sender sent it).
TLS can provide data confidentiality (obscuring the data from third parties observing the dialog over the connection).
