+This file provides guidance to AI assistants when working with code in this repository. + +## Project Purpose + +A production-ready OpenID Connect (OIDC) Identity Provider (IdP) built in Flask. It is designed for self-hosting and homelab environments, uses a PostgreSQL database, and is deployed via Docker. It implements the full Authorization Code Flow with advanced user management. + +## How to Run the Server + +The primary way to run the server is with Docker Compose. + +```bash +# 1. Copy the production environment template +cp .env.production .env + +# 2. (Optional) Edit the .env file, especially OIDC_ISSUER +nano .env + +# 3. Build and start the services (in detached mode) +./deploy.sh +``` + +The server will be available on port 5000, with a PostgreSQL database running in a separate container. For local development outside of Docker, see the `README.md`. + +## Architecture Overview + +### Configuration (`config.py`, `.env`) + +- **Environment-based**: The application loads its configuration based on the `FLASK_ENV` environment variable (`development` or `production`). +- **`config.py`**: Contains three classes: `DevelopmentConfig`, `ProductionConfig`, and `TestingConfig`. The `get_config()` function returns the appropriate class. +- **`.env` file**: All secrets (like `SECRET_KEY`, `DATABASE_URL`) and environment-specific settings are loaded from this file using `python-dotenv`. +- **Validation**: `ProductionConfig` validates that all required environment variables are set, preventing startup with an incomplete configuration. + +### Main Application (`oidc_server.py`) + +- **Flask App**: The core of the application. It initializes the database, rate limiter, and loads the configuration. It also initializes `Flask-Migrate` for database schema migrations. +- **Blueprints**: The application is structured with Flask Blueprints for modularity: + - **OIDC Endpoints**: `/authorize`, `/token`, `/userinfo`, `/.well-known/openid-configuration`. + - **User-facing pages**: `/login`, `/register`, `/change-password`, `/dashboard`. + - **Admin Panel**: A complete admin section under `/admin/...` protected by an `@admin_required` decorator. +- **Templates**: All HTML templates are stored as strings in `templates.py` and `admin_templates.py` and rendered with `render_template_string` for simplicity. + +### Database Layer (`models.py`) + +SQLAlchemy ORM models define the database schema. + +1. **`User` Model**: + - Stores user credentials with **bcrypt-hashed** passwords. + - Implements roles (`role` field) and a flexible, JSON-based `permissions` system. + - Helper methods like `set_password()`, `check_password()`, `get_permissions()`, `has_permission()`. + - `is_admin` and `is_active` flags for access control. + +2. **`Client` Model**: + - Stores OIDC client applications. + - `client_id` is the public identifier. + - `client_secret_hash` stores the hashed client secret using bcrypt. + - `redirect_uris` and `allowed_scopes` are stored as JSON strings. + +3. **`AuthorizationCode` Model**: + - Stores temporary authorization codes with a configurable TTL (Time To Live). + - `is_valid()` method checks if the code is expired or has already been used. + - One-time use is enforced by the `used` flag. + +3. **`AccessToken` Model**: + - Stores issued access tokens with a configurable TTL. + - Can be invalidated using the `revoked` flag. + +4. **`AuditLog` Model**: + - **New**: Logs critical security events. + - A class method `AuditLog.log()` is used to easily create new log entries. + - Tracks actions like `login_success`, `login_failed`, `user_created`, `user_deleted`, etc. + - Stores IP address, User-Agent, and other relevant details. + +### Security Features + +- **Rate Limiting**: `Flask-Limiter` is used to protect sensitive endpoints like `/login`, `/admin/login`, and `/token` from brute-force attacks. +- **Audit Logging**: All important user and admin actions are logged to the `audit_logs` table for security analysis. +- **Password Security**: Passwords are never stored in plaintext. `bcrypt` is used for hashing. +- **Admin Protection**: The admin area is protected by a decorator (`@admin_required`) that checks for a valid admin session and ensures the user has admin privileges. + +## Key Implementation Details + +- **OIDC Flow**: The standard flow is implemented across `/authorize` and `/token`. The ID token is signed using **RS256** with a private key. The corresponding public key is exposed via the `/jwks` endpoint. +- **Database Migrations**: The database schema is managed by `Flask-Migrate` (Alembic). The `flask db upgrade` command applies migrations, and the `flask seed` command populates the database with initial users. +- **Token Cleanup**: `cleanup_expired_tokens()` provides a way to periodically remove expired tokens from the database. + +## Security Status + +This is an overview of security features from the `TODO.md` file. + +- ✅ **bcrypt password hashing** +- ✅ **Persistent database storage** +- ✅ **User self-service registration & password change** +- ✅ **Rate Limiting** on critical endpoints +- ✅ **Audit Logging** for security-relevant events +- ✅ **Environment-based config** (no secrets in code) +- ✅ **Asymmetric JWT signing (RS256)** +- ✅ **Database migrations (Alembic)** +- ✅ **Multi-client support** (managed in the database) +- ✅ **Docker support** with a non-root user + +- ⚠️ **Still needs for full OIDC compliance and higher security**: + - Refresh Tokens. + - PKCE support for public clients (SPAs, mobile apps). \ No newline at end of file diff --git a/Dockerfile b/Dockerfile new file mode 100644 index 0000000..499ee39 --- /dev/null +++ b/Dockerfile @@ -0,0 +1,51 @@ +# Multi-stage Build für OIDC Identity Provider +FROM python:3.10-slim as base + +# System dependencies +RUN apt-get update && apt-get install -y \ + gcc \ + postgresql-client \ + && rm -rf /var/lib/apt/lists/* + +# Working directory +WORKDIR /app + +# Copy requirements first (for better caching) +COPY requirements.txt . + +# Install Python dependencies +RUN pip install --no-cache-dir -r requirements.txt gunicorn + +# Copy application code +COPY config.py . +COPY models.py . +COPY oidc_server.py . + +# Copy app package with services +COPY app/ app/ + +# Copy templates directory with HTML templates +COPY templates/ templates/ + +# Copy migrations directory for database schema management +COPY migrations/ migrations/ + +# Copy instance directory with JWT keys +COPY instance/ instance/ + +# Copy static directory with CSS files +COPY static/ static/ + +# Create non-root user and set permissions +RUN useradd -m -u 1000 oidc && chown -R oidc:oidc /app +USER oidc + +# Expose port +EXPOSE 5000 + +# Health check +HEALTHCHECK --interval=30s --timeout=5s --start-period=10s --retries=3 \ + CMD python -c "import requests; requests.get('http://localhost:5000/health')" || exit 1 + +# Start with Gunicorn (production WSGI server) +CMD ["gunicorn", "--bind", "0.0.0.0:5000", "--workers", "4", "--threads", "2", "--timeout", "60", "oidc_server:app"] diff --git a/Dockerfile.debug b/Dockerfile.debug new file mode 100644 index 0000000..e630942 --- /dev/null +++ b/Dockerfile.debug @@ -0,0 +1,6 @@ +FROM python:3.10-slim +WORKDIR /app +COPY requirements.txt . +RUN pip install --no-cache-dir -r requirements.txt +COPY debug_import.py . +CMD ["python3", "debug_import.py"] diff --git a/README.md b/README.md new file mode 100644 index 0000000..8fa1bfe --- /dev/null +++ b/README.md @@ -0,0 +1,198 @@ +# OpenID Connect (OIDC) Identity Provider + +Ein produktionsbereiter OIDC Identity Provider (IdP) in Flask, konzipiert für Homelab- und Self-Hosting-Umgebungen.

For a general overview, see the `README.md` file. + +## 1. High-Level Overview + +The application is a standard Flask web server that follows a monolithic architecture. It is designed to be run as a containerized service using Docker. + +The main components are: + +- **Flask Application (`oidc_server.py`)**: The core of the application, which handles all incoming requests, business logic, and OIDC flows. +- **Database (`models.py`)**: A PostgreSQL or SQLite database, managed by SQLAlchemy, that persists all data, including users, clients, tokens, and logs. +- **Configuration (`config.py` & `.env`)**: A flexible, environment-based configuration system for managing settings and secrets. +- **Templates (`templates.py` & `admin_templates.py`)**: In-memory HTML templates for rendering the user interface. + +## 2. Configuration System + +The application uses a layered configuration approach to separate concerns and keep secrets out of the codebase. + +- **.env File**: This file (which is not committed to version control) is used to store all secrets and environment-specific settings. It is loaded at startup using `python-dotenv`. +- **`config.py`**: This file defines several configuration classes (`DevelopmentConfig`, `ProductionConfig`, `TestingConfig`) that inherit from a base `Config` class. It reads values from the environment (populated by the `.env` file) and sets sane defaults. +- **`oidc_server.py`**: At startup, the main application file reads the `FLASK_ENV` environment variable to determine which configuration class to load from `config.py`. This ensures that the correct settings (e.g., database URI, debug mode) are used for the environment. + +## 3. Application Structure (`oidc_server.py`) + +The main application file is responsible for: + +1. **Initialization**: + - Creating the Flask `app` instance. + - Loading the correct configuration object. + - Initializing the database connection (`db.init_app(app)`). + - Initializing `Flask-Migrate` for database schema management. + - Initializing `Flask-Limiter` for rate limiting. + +2. **Routing**: All of the application's routes are defined here. They can be grouped into: + - **OIDC Endpoints**: Standard endpoints required by the OpenID Connect specification (`/authorize`, `/token`, `/userinfo`, `/.well-known/openid-configuration`, `/jwks`). + - **User-Facing Pages**: Routes for user interaction, such as `/login`, `/register`, and `/dashboard`. + - **Admin Panel**: A set of routes under the `/admin/` prefix for managing users and clients. These routes are protected by the `@admin_required` decorator. + +3. **CLI Commands**: The application defines custom `flask` commands, such as: + - `flask db`: For managing database migrations (e.g., `flask db upgrade`). + - `flask seed`: For populating the database with initial test data (users and clients). + +## 4. Database Models (`models.py`) + +All data is stored in a relational database, and the schema is defined using SQLAlchemy ORM models. + +- **`User`**: Stores user information, including a hashed password (using `bcrypt`), role, and a flexible JSON-based permissions list. +- **`Client`**: Stores information about OIDC client applications. Each client has a `client_id`, a hashed `client_secret`, a list of allowed `redirect_uris`, and a list of `allowed_scopes`. +- **`AuthorizationCode`**: A temporary, single-use code that is issued during the first leg of the OIDC flow. It has a short TTL and is marked as used after it is exchanged for a token. +- **`AccessToken`**: A token that grants access to the `/userinfo` endpoint. It has a configurable lifetime and can be revoked. +- **`AuditLog`**: Records important security-related events, such as login attempts, user creation, and client modifications. + +## 5. OIDC Authorization Code Flow + +The core logic of the IdP is its implementation of the OIDC Authorization Code Flow. + +1. **`/authorize` (GET)**: + - A client application redirects the user to this endpoint. + - The server validates the `client_id` and `redirect_uri` against the `Client` table in the database. + - It stores the authorization request parameters in the user's session and displays a login page. + +2. **`/authorize` (POST)**: + - The user submits their credentials. + - The server validates the username and password against the `User` table. + - On success, it generates a new `AuthorizationCode`, saves it to the database, and redirects the user back to the client's `redirect_uri` with the code included as a query parameter. + +3. **`/token` (POST)**: + - The client application makes a direct, back-channel request to this endpoint, sending the authorization code along with its `client_id` and `client_secret`. + - The server validates the client's credentials and the authorization code. + - It marks the authorization code as used. + - It generates a new `AccessToken` and an `id_token` (a JWT signed with the `RS256` algorithm). + - It returns the tokens to the client in a JSON response. + +4. **`/userinfo` (GET)**: + - The client can use the `AccessToken` to request information about the user from this endpoint. + - The server validates the access token and returns the user's claims (e.g., name, email). + +This flow ensures that the user's credentials are never exposed to the client application and that tokens are securely issued and validated. diff --git a/docs/PRODUCTION_READY.md b/docs/PRODUCTION_READY.md new file mode 100644 index 0000000..4c7d692 --- /dev/null +++ b/docs/PRODUCTION_READY.md @@ -0,0 +1,285 @@ +# Production Deployment - Ready to Deploy! 🚀 + +Your OIDC Identity Provider is now production-ready with minimal configuration needed. + +## What Was Created + +### 1.

For testing, it's easiest to run it locally: + +```bash +# In your first terminal +export FLASK_APP=oidc_server.py +export FLASK_ENV=development + +# Make sure your database is up-to-date +flask db upgrade +flask seed + +# Run the OIDC server (defaults to port 5000) +flask run +``` + +### Step 2: Run the Test Client + +The test client is pre-configured to work with the default settings of the OIDC server running on `localhost:5000`. + +In a second terminal, run the `test_client.py` application: + +```bash +# In your second terminal +python3 test_client.py +``` + +This will start the test client on `http://localhost:8080`. + +### Step 3: Perform the Test + +1. **Open your browser** and navigate to the test client's URL: `http://localhost:8080`. +2. **Click the "Mit OIDC einloggen" button.** This will redirect you to the OIDC server's login page. +3. **Log in** with one of the test user accounts (e.g., `test` / `test123`). +4. **Successful Login**: After a successful login, the OIDC server will redirect you back to the test client's callback URL (`/callback`). +5. **Token Exchange**: The test client will automatically exchange the received authorization code for an access token and an ID token. +6. **View Results**: The test client's homepage will now display the user information retrieved from the `/userinfo` endpoint, as well as the contents of the access token and the ID token. + +This process allows you to manually verify that the entire OIDC flow is working as expected. + +## Future Improvements + +- **Automated Integration Tests**: The `test_client.py` could be extended to make automated requests and assertions instead of requiring manual browser interaction. +- **Unit Tests**: A suite of unit tests should be created to test individual functions and components in isolation (e.g., model logic, specific OIDC validation rules). +- **PyTest Framework**: The project should adopt the PyTest framework for writing and running tests in a structured way. diff --git a/docs/TODO.md b/docs/TODO.md new file mode 100644 index 0000000..f63ee17 --- /dev/null +++ b/docs/TODO.md @@ -0,0 +1,210 @@ +# OIDC Server - TODO & Roadmap + +## ✅ Bereits implementiert + +### Core OIDC Funktionalität +- ✅ Authorization Code Flow (vollständig implementiert) +- ✅ Discovery Endpoint (`/.well-known/openid-configuration`) +- ✅ `/authorize` - Authorization Endpoint +- ✅ `/token` - Token Exchange +- ✅ `/userinfo` - User Info Endpoint +- ✅ JWT ID Tokens (signiert mit RS256) +- ✅ Access Tokens mit Validation +- ✅ Authorization Codes mit TTL + +### User Management +- ✅ User Registration (Self-Service) +- ✅ Password Change (Self-Service) +- ✅ Bcrypt Password Hashing +- ✅ User Login mit Session +- ✅ User Dashboard + +### Admin Features +- ✅ Admin Login (separate Session) +- ✅ CRUD für User-Verwaltung +- ✅ Rollen-System (user, admin, moderator, readonly) +- ✅ Permissions-System (JSON Array, comma-separated UI) +- ✅ User Activate/Deactivate +- ✅ **(NEU)** Multi-Client Support - OIDC-Clients können über das Admin-Panel verwaltet werden. + +### Security & Data +- ✅ SQLite Database (PostgreSQL-ready) +- ✅ Session-based Authentication +- ✅ CSRF Protection (state parameter) +- ✅ Sichere Landing Page (keine Secrets exposed) +- ✅ **(NEU)** Rate Limiting - Schutz vor Brute-Force auf Login/Token Endpoints +- ✅ **(NEU)** Audit Logging - Loggt Logins und Admin-Aktionen in die Datenbank +- ✅ **(NEU)** Asymmetric Token Signing (RS256) - ID Tokens werden mit RS256 signiert und der Public Key per `/jwks` Endpoint bereitgestellt. + +### DevOps/Production +- ✅ **(NEU)** Environment Configuration - `.env` File Support für Secrets (Development/Production) +- ✅ **(NEU)** Health Check Endpoint - `/health` für Monitoring und Load Balancer +- ✅ **(NEU)** Docker Support - `Dockerfile` und `docker-compose.yml` für einfaches Deployment +- ✅ **(NEU)** Production WSGI Server - Gunicorn wird im Docker Container verwendet +- ✅ **(NEU)** Database Migrations - Schema-Änderungen werden mit Flask-Migrate (Alembic) verwaltet. + +### UI/UX +- ✅ Modernes Dark Mode Design +- ✅ Responsive Layout +- ✅ Alle Templates mit Theme Toggle + +--- + +## 🚀 TODO - Nächste Features + +### Security Improvements (Priorität: HOCH) + +#### 2.

+**Date**: 2025-11-28 +**Duration**: ~1.5 hours +**Status**: ✅ **COMPLETE** + +--- + +## 🎯 Objective + +1. **Unify Login System**: Merge separate admin and user login into a single endpoint +2. **Implement Analytics Dashboard**: Create comprehensive session analytics for admins and users +3. **Improve Navigation**: Add clear navigation links to new features + +--- + +## ✅ What Was Accomplished + +### **Phase 1: Login System Unification** + +#### **Removed Duplicate Login Infrastructure** +1. ✅ Deleted `/admin/login` endpoint (oidc_server.py:73-96) +2. ✅ Removed `authenticate_admin()` method from AuthService (auth_service.py:169-216) +3. ✅ Unified session handling - only `session['user_id']` (previously: `admin_user_id` + `user_id`) +4. ✅ Updated `/admin/logout` to use unified session clearing + +#### **Updated Authentication Flow** +**Before:** +```python +# Two separate login endpoints +/login → session['user_id'] = user.id +/admin/login → session['admin_user_id'] = user.id + +# Admin decorator checked both +admin_id = session.get('admin_user_id') or session.get('user_id') +``` + +**After:** +```python +# Single login endpoint +/login → session['user_id'] = user.id + ↓ + is_admin? → /admin/users + ↓ + regular? → /dashboard + +# Admin decorator checks one session +user_id = session.get('user_id') +``` + +#### **Enhanced Login Redirect Logic** (oidc_server.py:509-519) +- Supports `?redirect=admin` parameter for direct admin access +- Auto-redirects admins to `/admin/users` +- Auto-redirects regular users to `/dashboard` +- Handles access denied scenarios with error messages + +--- + +### **Phase 2: Analytics Dashboard Implementation** + +#### **Service Layer Enhancement** + +**AnalyticsService**

sessions system-wide +- See total active users count +- See total active tokens count +- See total clients in use +- View sessions grouped by client application +- See each session: username, email, created time, expiry + +**Access Control:** +- Requires `@admin_required` decorator +- Must have `user.is_admin = True` +- Must be logged in via `/login` + +**Use Cases:** +- System monitoring +- Security audits +- Usage analytics +- Capacity planning +- Identifying inactive clients + +### **User Analytics** (`/my-sessions`) + +**Capabilities:** +- View OWN active sessions only +- See personal session count +- See how many apps user is using +- View session details per application +- Check session expiration times + +**Access Control:** +- Requires login (any active user) +- Automatically filtered to `user_id` +- No admin privileges needed + +**Use Cases:** +- Session management +- Security awareness +- Logout from unknown sessions (future feature) +- Check which apps are connected +- Monitor session expiration + +--- + +## 💡 Benefits Achieved + +### **User Experience:** +1. **Simplified Login**: One login page for everyone +2. **Transparency**: Users can see their active sessions

analytics data as CSV/JSON +- [ ] Add date range filters to analytics + +### **Medium Term:** +- [ ] Session activity timeline +- [ ] Login location/IP tracking +- [ ] Suspicious login alerts +- [ ] Session activity graphs (Chart.js) + +### **Long Term:** +- [ ] Refresh token analytics +- [ ] Failed login attempt dashboard +- [ ] User behavior analytics +- [ ] API usage statistics per client + +--- + +## 📝 Key Learnings + +### **Architecture Decisions:** + +1. **Single Login Pattern**: + - Simpler UX and fewer security edge cases + - Role-based routing after authentication + - Consistent audit trail + +2. **Privacy by Design**: + - Filter at service layer, not template layer + - Clear separation: admin sees all, user sees own + - No accidental data leakage + +3. **Auto-Refresh Analytics**: + - 30-second refresh provides near real-time view + - No WebSocket complexity needed + - Simple JavaScript timeout + +4. **Repository Pattern**: + - Complex SQL queries isolated in repository + - Service layer focuses on business logic + - Easy to swap database if needed + +### **Code Quality:** + +- ✅ Type hints on all service methods +- ✅ Comprehensive docstrings +- ✅ Clear separation of concerns +- ✅ No business logic in endpoints +- ✅ DRY principle applied + +--- + +## 🙏 Summary + +**Mission Accomplished:** Successfully unified the login system and implemented a
