Security is often enhanced in large, heterogeneous applications by authenticating logins with a central repository. Adaptive Server supports a variety of external authentication methods:
Kerberos – provides a centralized and secure authentication mechanism in enterprise environments that includes the Kerberos infrastructure. Authentication occurs with a trusted, third-party server called a key distribution center to verify both the client and the server.
LDAP user authentication – Lightweight Directory Access Protocol (LDAP) provides a centralized authentication mechanism based on a user’s login name and password.
PAM user authentication – Pluggable Authentication Module (PAM) provides a centralized authentication mechanism that uses operating system interfaces for both administration and runtime application operations.
For more information about each of these methods of external authentication, see Chapter 5, “External Authentication.”
