Mar 1, 2025March 2025 Monthly Summary for MultiDirectory: Delivered core improvements to session management, LDAP reliability, and Traefik-based infrastructure integration, driving security, performance, and maintainability. Implemented a revamped session data model with sorted sets, IP metadata, and clear separation of HTTP vs LDAP sessions, enabling scalable session handling and better observability. Fixed critical LDAP 2FA edge-case, strengthened session lifecycle operations (clear and expire), and introduced a Redis-backed pipeline for efficient batch-clearing of user sessions. Expanded Traefik proxy protocol support with a dedicated proxy-protocol package and related configuration, and advanced code quality and test coverage through linting, refactors, and documentation updates. These changes reduce risk in auth flows, improve scalability for large user bases, and boost developer productivity through cleaner code and better test coverage.
