feat: HR Portal - Complete Multi-Tenant System with Redis Session Storage
Major Features: - ✅ Multi-tenant architecture (tenant isolation) - ✅ Employee CRUD with lifecycle management (onboarding/offboarding) - ✅ Department tree structure with email domain management - ✅ Company info management (single-record editing) - ✅ System functions CRUD (permission management) - ✅ Email account management (multi-account per employee) - ✅ Keycloak SSO integration (auth.lab.taipei) - ✅ Redis session storage (10.1.0.254:6379) - Solves Cookie 4KB limitation - Cross-system session sharing - Sliding expiration (8 hours) - Automatic token refresh Technical Stack: Backend: - FastAPI + SQLAlchemy - PostgreSQL 16 (10.1.0.20:5433) - Keycloak Admin API integration - Docker Mailserver integration (SSH) - Alembic migrations Frontend: - Next.js 14 (App Router) - NextAuth 4 with Keycloak Provider - Redis session storage (ioredis) - Tailwind CSS Infrastructure: - Redis 7 (10.1.0.254:6379) - Session + Cache - Keycloak 26.1.0 (auth.lab.taipei) - Docker Mailserver (10.1.0.254) Architecture Highlights: - Session管理由 Keycloak + Redis 統一控制 - 支援多系統 (HR/WebMail/Calendar/Drive/Office) 共享 session - Token 自動刷新,異質服務整合 - 未來可無縫遷移到雲端 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
