Multi-System SSO Authentication

소개

This skill provides production-grade implementation patterns for complex authentication architectures that integrate with multiple enterprise identity providers. It enables robust JWT RS256 signature validation with authoritative system verification, unified routing based on issuer claims, and seamless mapping of diverse permission structures into a unified application format. By handling everything from Redis session management to legacy Laravel session decryption, it ensures secure and scalable authentication across microservices and legacy integrations.
