Which type of authentication is used in an SSO configuration with LDAP?

In a Single Sign-On (SSO) configuration that utilizes LDAP (Lightweight Directory Access Protocol), web-tier authentication is the most relevant method. This approach allows users to authenticate to multiple applications without needing to log in to each one individually, using credentials that are validated against an LDAP directory.

Web-tier authentication serves as an intermediary layer between the application and the authentication services, allowing the application to rely on the network identity provider (in this case, the LDAP server) to manage the credentials and authentication. When a user logs in from a web application, their credentials are sent to the web-tier, which then communicates with the LDAP for validation. If successful, the user gains access to various resources associated with their identity without needing to authenticate separately for each resource.

Other forms of authentication such as form-based, token-based, or network authentication might not align directly with the principles of SSO in this context. Form-based authentication typically requires users to provide their credentials through a Web form, while token-based authentication relies on the use of security tokens that may not directly integrate with LDAP for centralized user management. Network authentication often refers to securing a network connection and is less about user identity management across multiple services.

Therefore, in the context of SSO integration with
