fix: Complete Keycloak external IdP integration with all tests passing
...
This commit completes the Keycloak external IdP integration for the MCP
server, implementing ADR-002 Tier 2 (External Identity Provider) with
full Bearer token authentication support.
Key Changes:
1. **Keycloak backchannel-dynamic configuration**
- Added --hostname-strict=false and --hostname-backchannel-dynamic=true
- Allows external issuer (localhost:8888) with internal endpoints (keycloak:8080)
- Solves Docker networking issue where containers can't reach localhost
2. **CORSMiddleware Bearer token patch**
- Created app-hooks/patches/cors-bearer-token.patch from upstream commit 8fb5e77db82
- Allows Bearer tokens to bypass CORS/CSRF checks (stateless authentication)
- Applied via post-installation hook 20-apply-cors-bearer-token-patch.sh
- Enables app-specific APIs (Notes, Calendar, etc.) to work with Bearer tokens
3. **Patch organization**
- Moved patches to app-hooks/patches/ directory
- Updated docker-compose.yml to mount entire app-hooks directory
- Consolidated patch management for better maintainability
4. **Test improvements**
- All 11 Keycloak integration tests passing
- Tests validate OAuth token acquisition, MCP connectivity, token validation,
tool execution, token persistence, user provisioning, scope filtering,
and error handling
Architecture:
- Keycloak acts as external OAuth/OIDC identity provider
- MCP server uses Keycloak tokens to access Nextcloud APIs
- Nextcloud user_oidc app validates Bearer tokens from Keycloak
- No admin credentials needed - all API access uses user's OAuth tokens
Cache Note:
- Discovery and JWKS caches must be cleared when switching Keycloak configurations
- Use: docker compose exec redis redis-cli DEL "<cache-key>"
- Or: docker compose exec app php occ user_oidc:provider keycloak --clientid nextcloud

test: Replace persistent OAuth client cache with session-scoped fixtures
...
Remove file-based caching of OAuth client credentials and implement automatic
client lifecycle management for test fixtures.
Changes:
- Add RFC 7592 client deletion function in auth/client_registration.py
- Remove cache_file parameter from _create_oauth_client_with_scopes helper
- Update all OAuth credential fixtures to use yield/finalizer pattern
- Add automatic client cleanup at end of test session (best-effort)
- Remove persistent .nextcloud_oauth_*.json cache files
Benefits:
- No persistent cache files cluttering repository
- Fresh OAuth clients created for each test session via DCR
- Automatic cleanup attempts (RFC 7592 DELETE endpoint)
- Cleaner test environment with proper fixture lifecycle
Note: Client deletion may fail due to Nextcloud authentication middleware
(logged as warning). The key improvement is removing persistent cache files.
OAuth clients may accumulate in Nextcloud but can be cleaned manually.
