Description
Passwords need to be protected at all times, and encryption is the standard method for protecting passwords during transmission. Application servers have the capability to utilize LDAP directories for authentication. If LDAP connections are not protected during transmission, sensitive authentication credentials can be stolen. When the application server utilizes LDAP, the LDAP traffic must be encrypted.
