SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires jose, httpx, redis, pycryptodomex, phpserialize.

What problem does it solve?

This Skill eliminates the complexity of integrating multiple enterprise Single Sign-On (SSO) providers, handling intricate JWT validation, session management, and permission mapping. It reduces development effort and enhances security for applications operating in diverse authentication environments.

Core Features & Use Cases

  • Unified Authentication Adapter: Routes tokens to the correct SSO adapter based on the JWT issuer, streamlining integration with various identity providers.
  • Secure JWT RS256 Validation: Implements robust token verification, including backwards checks with authoritative SSO systems, to prevent token replay and ensure validity.
  • Laravel Session Decryption & Redis Management: Supports seamless integration with legacy Laravel session-based authentication alongside modern JWT, facilitating smooth transitions and unified user experiences.
  • Use Case: Integrate a new microservice into an existing enterprise ecosystem that uses multiple SSO providers (e.g., Okta, Azure AD, custom systems) and legacy Laravel applications, ensuring consistent and secure user authentication and authorization.

Quick Start

Implement a new authentication adapter for a new SSO provider, ensuring it adheres to the IAuthAdapter interface and integrates seamlessly with the UnifiedAuthAdapter.

Frequently Asked Questions about multi-system-sso-authentication

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I integrate multiple SSO providers into a single application?▼

Multi-system SSO authentication unifies several identity providers through a routing adapter that directs tokens to the correct SSO handler based on JWT issuer, eliminating separate integration logic for each provider and centralizing authentication control.

Can I validate JWT tokens from different enterprise SSO systems securely?▼

Yes, secure JWT RS256 validation performs token signature verification against issuer public keys, executes backwards checks with authoritative SSO systems to prevent replay attacks, and ensures tokens remain valid across your application ecosystem.

How do I handle both modern JWT and legacy Laravel session authentication together?▼

This Skill decrypts Laravel sessions and manages them alongside JWT via Redis-based session storage, allowing gradual migration from legacy frameworks to modern token-based auth without breaking existing user experiences or requiring simultaneous system rewrites.

What's the best way to map SSO provider permissions to internal application roles?▼

A unified adapter architecture normalizes permissions from different SSO providers into your internal role structure, supporting token issuer routing and cross-system permission mapping so authorization remains consistent regardless of which provider authenticated the user.

Do I need to build separate adapters for each new SSO provider I add?▼

Yes, you implement a new adapter adhering to the `IAuthAdapter` interface for each SSO provider, but the unified architecture handles integration automatically—new adapters slot into the existing routing system without modifying core authentication logic.

What happens if a JWT token is revoked or becomes invalid mid-session?▼

Token revocation is managed through Redis-based session tracking and backwards verification with authoritative SSO systems, ensuring revoked tokens are immediately rejected and invalid sessions cannot grant access to protected resources.
