Secure communication with SSL
Depending on the authentication type being used between the LDAP client and server, passwords are sent in either crypted format (unix_auth) or in clear text (ldap_auth). Use Secure Socket Layer (SSL) to protect against security exposure when you send even encrypted passwords over the network, or, in some cases, the Internet. AIX provides packages for SSL that can provide secure communication between directory servers and clients.
