What authentication method can be configured for single sign-on in a middleware/server scenario?

In a middleware/server scenario, Kerberos is the authentication method that is ideally suited for enabling single sign-on (SSO) capabilities. Kerberos utilizes a ticketing system that allows users to authenticate once and gain access to multiple services without needing to repeatedly log in. This single sign-on experience is made possible by the way Kerberos securely handles user authentication and session management.

When a user logs in for the first time, they receive a Kerberos ticket that can be used to access various services within the network without requiring additional logins. This system is particularly effective in enterprise environments where multiple applications and services need to be accessed frequently by users, as it enhances user convenience and security.

Other methods like OAuth, Basic Authentication, and Token-based Authentication also provide authentication mechanisms but are generally not as streamlined for SSO in traditional middleware/server configurations when compared to Kerberos. OAuth, for example, is specifically designed for third-party authorization and may require more complex interactions with APIs, while Basic Authentication typically requires users to send credentials with each request, thus not providing a true single sign-on experience. Token-based authentication systems can also be used for SSO but often rely on JWTs or similar mechanisms that may not fit standard middleware scenarios directly.

Therefore, Kerberos stands
