Security is often enhanced in large, heterogeneous applictions 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 include the Kerberos infrastructure. Authentication occurs with a trusted, third-party server calls a Key Distribution Center (KDC) 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 interfaces provided by the operating system for both administration and runtime application interfaces.
For more information about each of these methods of external authentication, see Chapter 16, “External Authentication.”
