Implement Official Keycloak JS Adapter with Proxy-Aware Configuration
MAJOR ENHANCEMENT: Complete Keycloak integration with proper HTTPS/proxy handling ## Core Improvements: ### 1. Enhanced Configuration (nuxt.config.ts) - Added proxy trust configuration for nginx environments - Configured baseUrl for production HTTPS enforcement - Added debug mode configuration for development ### 2. Proxy-Aware Keycloak Composable (composables/useKeycloak.ts) - Intelligent base URL detection (production vs development) - Force HTTPS redirect URIs in production environments - Enhanced debugging and logging capabilities - Proper PKCE implementation for security - Automatic token refresh mechanism ### 3. Dual Authentication System - Updated middleware to support both Directus and Keycloak - Enhanced useUnifiedAuth for seamless auth source switching - Maintains backward compatibility with existing Directus users ### 4. OAuth Flow Implementation - Created proper callback handler (pages/auth/callback.vue) - Comprehensive error handling and user feedback - Automatic redirect to dashboard on success ### 5. Enhanced Login Experience (pages/login.vue) - Restored SSO login button with proper error handling - Maintained existing Directus login form - Clear separation between auth methods with visual divider ### 6. Comprehensive Testing Suite (pages/dashboard/keycloak-test.vue) - Real-time configuration display - Authentication status monitoring - Interactive testing tools - Detailed debug logging system ## Technical Solutions: **Proxy Detection**: Automatically detects nginx proxy and uses correct HTTPS URLs **HTTPS Enforcement**: Forces secure redirect URIs in production **Error Handling**: Comprehensive error catching with user-friendly messages **Debug Capabilities**: Enhanced logging for troubleshooting **Security**: Implements PKCE and secure token handling ## Infrastructure Compatibility: - Works with nginx reverse proxy setups - Compatible with Docker container networking - Handles SSL termination at proxy level - Supports both development and production environments This implementation specifically addresses the HTTP/HTTPS redirect URI mismatch that was causing 'unauthorized_client' errors in the proxy environment.
