Here is the actionable refactor checklist toward: reusable npm core + standalone server + nfpm packaging.

High-Level Phases
[ ] Phase 1: Workspace bootstrap
[ ] Create root package.json (private, workspaces: npm, server)
[ ] Move current package.json to package.json (adjust paths)
[ ] Add root .npmrc (save-exact=true optional)

[ ] Phase 2: Core module scaffold (@ldap-gateway/core)
[ ] Create package.json (name, version 0.1.0, build script)
[ ] Add interfaces: AuthProvider, DirectoryProvider
[ ] Add LdapEngine skeleton (bind + minimal search)
[ ] Export via npm/src/index.js
[ ] Build: npm -w npm run build (ensure dist/index.js produced)

[ ] Phase 3: Adapt existing server into server/ package
[ ] Copy legacy src/ code into server/src/
[ ] Rename original server.js to serverMain.js
[ ] Replace direct ldapjs usage with LdapEngine
[ ] Implement provider factory that wraps existing backends
[ ] Ensure env loading isolated (bootstrapEnv.js if needed)
[ ] Update scripts (bundle, bin) to point to serverMain.js

[ ] Phase 4: Resolve path + runtime concerns
[ ] Standardize config search order (.env in CWD, /etc/ldap-gateway/.env)
[ ] Centralize logging adapter (map existing Winston config)
[ ] Extract reusable utilities (filter parsing, entry mapping) into core (one at a time)
[ ] Remove duplicated logic remaining in server after extraction (DRY pass)

[ ] Phase 5: Stabilize Core API
[ ] Flesh out search handler parity (users, groups, filters)
[ ] Add error normalization (map internal errors to ldapjs errors)
[ ] Add event hooks (bindSuccess, bindFail, searchRequest, searchResponse)
[ ] Document provider contracts (README in npm/)

[ ] Phase 6: Packaging (binary)
[ ] Confirm build: npm -w server run build (pkg outputs dist/ldap-gateway)
[ ] Add .env.example to server/
[ ] Smoke test binary without Node installed

[ ] Phase 7: nfpm packaging
[ ] Create nfpm/nfpm.yaml
[ ] Add nfpm/systemd/ldap-gateway.service
[ ] Add nfpm/scripts/postinstall.sh (user/group creation, mkdir /var/log/ldap-gateway)
[ ] Add nfpm/scripts/preremove.sh (optional cleanup)
[ ] Generate .deb/.rpm locally (nfpm pkg -f nfpm/nfpm.yaml)

[ ] Phase 8: Homebrew (later)
[ ] Produce tarball (binary + .env.example + LICENSE)
[ ] Create Formula template (defer until versioning stable)

[ ] Phase 9: CI workflow
[ ] GitHub Actions: build core -> build server -> produce binary -> nfpm -> upload artifacts
[ ] Cache node_modules per workspace
[ ] Optional release tagging flow

[ ] Phase 10: Cleanup & Docs
[ ] Remove obsolete top-level server.js and old scripts
[ ] Update README with new structure + embedding example
[ ] Add migration notes for downstream consumers
[ ] Update copilot-instructions.md to reflect modular layout

Quality / Guardrails
[ ] Keep each extraction commit behavior-neutral (KISS/DRY)
[ ] Run manual ldapsearch before/after major refactors
[ ] Avoid circular deps (core must not import server code)
[ ] Ensure no backends leak server-only env assumptions into core

Optional Enhancements
[ ] Add TypeScript typings (index.d.ts) for core
[ ] Add lightweight integration test (spin engine with mock providers)
[ ] Add version sync script (bump core + server referencing it)

🚀 Key Features

For Package Users

const { LdapEngine } = require('@ldap-gateway/core');
// Embed LDAP server in your app

For Server Operators

# Install package
sudo dpkg -i ldap-gateway_amd64.deb
sudo systemctl start ldap-gateway

For Developers

npm install
npm run build:all
npm test

🔄 Migration Path

v0.x → v1.0:

Old: Monolithic src/server.js
New: Modular @ldap-gateway/core + ldap-gateway-server
Breaking: Import paths changed, config structure standardized
Guide: See MIGRATION.md for detailed steps

📊 Test Coverage

✅ Core package builds successfully
✅ Server package builds successfully
✅ Binary executable runs
✅ Configuration loading works (env + file + CLI)
✅ LDAP operations functional (bind, search)
⚠️ Integration tests pending
⚠️ Package installation testing pending

🎯 Next Steps

Code Review: Review modular structure and patterns
Integration Testing: Test with real LDAP clients (SSSD, SSH)
Package Testing: Test .deb/.rpm installation on target systems
Performance Testing: Compare with legacy performance
Documentation Review: Ensure all docs are accurate
Merge to Main: After approval and testing

📝 Notes

All legacy code preserved in .attic/legacy-src/
No functionality lost - all features migrated
Backward compatible configuration (same .env format)
CI/CD ready for automated releases
Following DRY, KISS, and folder philosophy principles

Pull Request Overview

This PR introduces a massive architectural refactor that transforms the LDAP Gateway from a monolithic server into a modular system with a reusable npm core package and standalone server implementation. The refactor separates concerns between authentication/directory providers while adding comprehensive distribution support (binary releases, .deb/.rpm packages, Homebrew formula).

Key changes:

Introduced modular architecture with @ldap-gateway/core npm package and ldap-gateway-server standalone implementation
Added provider pattern with pluggable authentication and directory backends
Implemented comprehensive CI/CD pipeline with automated builds and releases
Created distribution packages for multiple platforms

server/package-lock.json: Language not supported

…lar-architecture-v1

Implement plugin-style backend architecture allowing custom auth and directory providers to be loaded from JavaScript files without rebuilding. Core Changes: - Add BackendLoader utility to scan and load backends from server/backends/ - Enhance ProviderFactory with dynamic backend support and fallback logic - Update serverMain.js to initialize dynamic loading at startup - Add comprehensive validation for backend interfaces Documentation & Examples: - Create detailed backend development guide (README.md) - Add template.js with auth and directory skeletons - Provide working examples: API auth and JSON file directory - Add QUICKSTART.md with Redis backend tutorial - Include IMPLEMENTATION.md documenting the complete feature Testing: - Add comprehensive test suite (12 test cases) - Cover valid/invalid backend loading - Test file filtering and fallback behavior - Verify options passing to constructors Key Features: - Drop JS files in server/backends/ to add custom backends - Automatic validation of required methods - Graceful fallback to compiled backends - Support for BACKEND_DIR environment variable - Full backward compatibility Files Changed: - server/utils/backendLoader.js (new, 230 lines) - server/providers.js (enhanced, +40 lines) - server/serverMain.js (updated initialization) - server/backends/ (new directory with 5 files, ~900 lines) - server/test/backendLoader.test.js (new, 250 lines) - README.md (added custom backends section) - .github/copilot-instructions.md (updated patterns)

…atterns - Add NotificationAuthProvider for MFA wrapper pattern - Move certificate logic to ConfigurationLoader - Remove duplicate LDAP server code from serverMain.js - Clean up LdapEngine by removing notification coupling - Delete authService.js (absorbed into provider architecture) - Centralize all environment variable access in config loader Establishes proper separation of concerns and clean abstraction boundaries.

…and updating build commands

- Replace generic 'db' backend with database-specific implementations - Add mysql.auth.js and mysql.directory.js for MySQL-specific operations - Add mongodb.auth.js and mongodb.directory.js for MongoDB-specific operations - Remove legacy DatabaseService and dbConfig.js dependencies - Fix database schema: use gid_number instead of gid for LDAP compatibility - Update MySQL init.sql and MongoDB init-mongo.js with correct schema - Update mysql.js driver to return gid_number for proper LDAP mapping - Add MongoDB test setup scripts and documentation - Update .env.example and setupUtils.js for new backend options BREAKING CHANGE: Legacy 'db' backend removed. Use 'mysql' or 'mongodb' instead. Fixes SSSD 'no gid provided' errors by ensuring proper gidNumber attributes.

Looks good to me, let's get an ldap-dev server in the opensource.mieweb.org cluster going to QA the changes before merging.

runleveldev

Ran acceptance tests against the staging server in the opensource cluster. Results follow:

On logging in to QA the changes, my account appears to have lost it's group membership. This breaks SUDO failing acceptance test 2:
