 * Interface for SSO (Single Sign-On) authenticator implementations.
 *
 * This interface defines the contract for SSO authentication providers that can be
 * integrated with Fess. Implementations handle specific SSO protocols like SAML,
 * OAuth, SPNEGO, or other authentication mechanisms. Each authenticator is responsible
 * for obtaining login credentials, resolving user information, and managing SSO
 * lifecycle operations like logout and metadata exchange.

Dex is an identity service that uses OpenID Connect to drive authentication for apps. Dex acts as a portal to other identity providers through "connectors." This lets dex defer authentication to LDAP servers, SAML providers, or established identity providers like GitHub, Google, and Active Directory. Clients write their authentication logic once to talk to dex, then dex handles the protocols for a given backend.

# Casdoor Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

Casdoor is a UI-first centralized authentication / Single-Sign-On (SSO) platform supporting OAuth 2.0, OIDC and SAML, integrated with Casbin RBAC and ABAC permission management. This document covers configuring Casdoor identity provider support with MinIO.
