About:
Dex is a federated identity service that enables single sign-on (SSO) for applications using the OpenID Connect and OAuth 2.0 protocols. It acts as a central authentication authority, issuing tokens after authenticating users against an external identity source like LDAP, SAML, or GitHub. This allows organizations to consolidate user management and provide secure, standardized access control to their internal services.

Key Features:

Federated authentication with external identity providers (LDAP, SAML, GitHub, etc.)
Native support for OIDC and OAuth 2.0 standards
Pluggable storage backend for user data (e.g., SQL, Kubernetes CRDs)
Lightweight and easy to deploy as a single binary

Use Cases:

Implementing centralized SSO for internal developer tools and dashboards
Providing a unified authentication layer for microservices architectures
Bridging legacy identity systems like LDAP to modern OIDC applications

Alternatives:

Keycloak – More feature-rich but significantly heavier and more complex to deploy than Dex.
Authentik – Offers a modern UI and built-in identity management workflows, whereas Dex is focused purely on being a lightweight OIDC provider.
