The DBMS must map the authenticated identity to the user account using PKI-based authentication.

Description
The cornerstone of the PKI is the private key used to encrypt or digitally sign information. The key by itself is a cryptographic value that does not contain specific user information. When including the DBMS in the Private Key Infrastructure, the authenticated user must map directly to a user account in the DBMS. If the user account is not directly tied to the authenticated identity, there is no way to know which, if any, database user account has been authorized. Transport Layer Security (TLS) is the successor protocol to Secure Sockets Layer (SSL). Although the Oracle configuration parameters have names including 'SSL', such as SSL_VERSION and SSL_CIPHER_SUITES, they refer to TLS.
