▼
Show error: "Authentication not available"
Scenario 2: Invalid Provider
User selects provider → GET /api/oauth2/connect?provider=invalid
│
▼
ProviderManager.getProvider("invalid") → undefined
│
▼
Return 400: "Provider not available"
Scenario 3: State Mismatch (CSRF Attack)
Callback received → state parameter doesn't match session
│
▼
Reject request → Redirect with error
│
▼
Display: "Invalid state (CSRF protection)"
Scenario 4: Token Exchange Failure
Exchange code for tokens → 401 Unauthorized
│
▼
Log error → Redirect with error
│
▼
Display: "Authentication failed"
Scenario 5: Provider Health Check Failure
Health check → Provider unreachable

▼
Mark as unavailable → Update status
│
▼
Frontend queries providers → Shows as unavailable
│
▼
User cannot select unavailable provider

{
"well_known_uris": [
{
"provider": "obp-oidc",
"url": "http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration"
},
{
"provider": "keycloak",
"url": "http://127.0.0.1:8180/realms/obp/.well-known/openid-configuration"
}
]
}
```
---
## Endpoints
### New Endpoints
| Method | Path | Description |
|--------|------|-------------|
| GET | `/api/oauth2/providers` | List available OIDC providers with status |
### Updated Endpoints
| Method | Path | Query Parameters | Description |
|--------|------|------------------|-------------|
| GET | `/api/oauth2/connect` | `provider` (optional), `redirect` (optional) | Initiate OAuth2 flow with selected provider |
| GET | `/api/oauth2/callback` | `code`, `state`, `error` (optional) | Handle OAuth2 callback from any provider |
---
## Session Data
### Login Initiation
```javascript
session = {
oauth2_provider: "obp-oidc", // Provider name
oauth2_code_verifier: "...", // PKCE code verifier
oauth2_state: "...", // CSRF state token
oauth2_redirect_page: "/resource-docs" // Redirect after auth
}
```
### After Token Exchange
```javascript
session = {
oauth2_provider: "obp-oidc", // Provider used
oauth2_access_token: "...", // Access token
oauth2_refresh_token: "...", // Refresh token
oauth2_id_token: "...", // ID token (JWT)
user: {
username: "john.doe",
email: "john@example.com",
name: "John Doe",
provider: "obp-oidc",
sub: "uuid-1234"
}
}
```
---
## Backward Compatibility
The implementation maintains full backward compatibility with the existing single-provider OAuth2 system:
1. **Legacy Environment Variable**: `VITE_OBP_OAUTH2_WELL_KNOWN_URL` still works
2. **Fallback Behavior**: If no provider parameter is specified, falls back to legacy OAuth2Service
3. **No Breaking Changes**: Existing deployments continue to work without changes
4. **Gradual Migration**: Can enable multi-provider incrementally
---
## Benefits
1. ✅ **User Choice** - Users select their preferred identity provider
2. ✅ **Dynamic Discovery** - Providers discovered from OBP API automatically
3. ✅ **Health Monitoring** - Real-time provider availability tracking
4. ✅ **Extensibility** - Add new providers via environment variables only
5. ✅ **Resilience** - Fallback to available providers if one fails
6. ✅ **Backward Compatible** - No breaking changes for existing deployments
---
## Next Steps
### Priority 1: Frontend Implementation
1. Update `HeaderNav.vue` to fetch and display available providers
2. Create `ProviderSelector.vue` component for provider selection
3. Test login flow with multiple providers
4. Handle error states gracefully
### Priority 2: Testing
1. Write unit tests for all new services
2. Create integration tests for multi-provider flow
3. Add E2E tests for login scenarios

# Multi-OIDC Provider Implementation - Executive Summary
## Overview
This document provides a high-level summary of implementing multiple OIDC provider support in API Explorer II, based on the proven architecture from OBP-Portal.
---
## Current State
**API Explorer II** currently supports OAuth2/OIDC authentication with a **single provider** configured via environment variables:
```bash
VITE_OBP_OAUTH2_WELL_KNOWN_URL=http://localhost:9000/obp-oidc/.well-known/openid-configuration
VITE_OBP_OAUTH2_CLIENT_ID=<client-id>
VITE_OBP_OAUTH2_CLIENT_SECRET=<client-secret>
```
**Limitations:**
- Only one OIDC provider supported at a time
- No user choice of authentication method
- Requires redeployment to switch providers
- No fallback if provider is unavailable
---
## Target State
**Multi-Provider Support** allows users to choose from multiple identity providers at login:
- **OBP-OIDC** - Open Bank Project's identity provider
- **Keycloak** - Enterprise identity management
- **Google** - Consumer identity (optional)
- **GitHub** - Developer identity (optional)
- **Custom** - Any OpenID Connect provider
---
## How OBP-Portal Does It
### 1. Dynamic Provider Discovery
OBP-Portal fetches available OIDC providers from the **OBP API**:
```
GET /obp/v5.1.0/well-known
```
**Response:**
```json
{
"well_known_uris": [
{
"provider": "obp-oidc",
"url": "http://localhost:9000/obp-oidc/.well-known/openid-configuration"
},
{
"provider": "keycloak",
"url": "http://localhost:8180/realms/obp/.well-known/openid-configuration"
}
]
}
```
### 2. Provider Manager
**Key Component:** `OAuth2ProviderManager`
**Responsibilities:**
- Fetch well-known URIs from OBP API
- Initialize OAuth2 client for each provider
- Track provider health (available/unavailable)
- Perform periodic health checks (60s intervals)
- Provide access to specific providers
### 3. Provider Factory
**Key Component:** `OAuth2ProviderFactory`
**Responsibilities:**
- Strategy pattern for provider-specific configuration
- Load credentials from environment variables
- Create OAuth2 clients with OIDC discovery
- Support multiple provider types
**Strategy Pattern:**
```typescript
strategies.set('obp-oidc', {
clientId: process.env.VITE_OBP_OAUTH2_CLIENT_ID,
clientSecret: process.env.VITE_OBP_OAUTH2_CLIENT_SECRET,
redirectUri: process.env.VITE_OBP_OAUTH2_REDIRECT_URL
})
strategies.set('keycloak', {
clientId: process.env.VITE_KEYCLOAK_CLIENT_ID,
clientSecret: process.env.VITE_KEYCLOAK_CLIENT_SECRET,
redirectUri: process.env.VITE_KEYCLOAK_REDIRECT_URL
})
```
### 4. User Flow
```
1. User clicks "Login"
→ Shows provider selection dialog
2. User selects provider (e.g., "OBP-OIDC")
→ GET /api/oauth2/connect?provider=obp-oidc
3. Server:
- Retrieves OAuth2 client for "obp-oidc"
- Generates PKCE parameters
- Stores provider name in session
- Redirects to provider's authorization endpoint
4. User authenticates on selected OIDC provider
5. Provider redirects back:
→ GET /api/oauth2/callback?code=xxx&state=yyy
6. Server:
- Retrieves provider from session ("obp-oidc")
- Gets corresponding OAuth2 client
- Exchanges code for tokens
- Stores tokens with provider name
7. User authenticated with selected provider
```
---
## Implementation Architecture for API Explorer II
### New Services
#### 1. **OAuth2ClientWithConfig** (extends `OAuth2Client` from arctic)
```typescript
class OAuth2ClientWithConfig extends OAuth2Client {
public OIDCConfig?: OIDCConfiguration
public provider: string
async initOIDCConfig(oidcConfigUrl: string): Promise<void>
getAuthorizationEndpoint(): string
getTokenEndpoint(): string
getUserInfoEndpoint(): string
}
```
#### 2. **OAuth2ProviderFactory**
```typescript
class OAuth2ProviderFactory {
private strategies: Map<string, ProviderStrategy>
async initializeProvider(wellKnownUri: WellKnownUri): Promise<OAuth2ClientWithConfig>
getConfiguredProviders(): string[]
}
```
#### 3. **OAuth2ProviderManager**
```typescript
class OAuth2ProviderManager {
private providers: Map<string, OAuth2ClientWithConfig>
async fetchWellKnownUris(): Promise<WellKnownUri[]>
async initializeProviders(): Promise<boolean>
getProvider(providerName: string): OAuth2ClientWithConfig
getAvailableProviders(): string[]
startHealthCheck(intervalMs: number): void
}
```
### Updated Controllers
#### 1. **OAuth2ProvidersController** (NEW)
```typescript
GET /api/oauth2/providers
→ Returns: { providers: [...], count: 2, availableCount: 1 }
```
#### 2. **OAuth2ConnectController** (UPDATED)
```typescript
GET /api/oauth2/connect?provider=obp-oidc&redirect=/resource-docs
→ Redirects to selected provider's authorization endpoint
```
#### 3. **OAuth2CallbackController** (UPDATED)
```typescript
GET /api/oauth2/callback?code=xxx&state=yyy
→ Uses provider from session to exchange code for tokens
```
### Frontend Updates
#### **HeaderNav.vue** (UPDATED)
**Before:**
```vue
<a href="/api/oauth2/connect">Login</a>
```
**After:**
```vue
<button @click="handleLoginClick">
Login
<span v-if="availableProviders.length > 1">▼</span>
</button>
<!-- Provider Selection Dialog -->
<el-dialog v-model="showProviderSelector">
<div v-for="provider in availableProviders">
<div @click="loginWithProvider(provider.name)">
{{ provider.name }}
</div>
</div>
</el-dialog>
```
---
## Configuration
### Environment Variables
```bash
# OBP-OIDC Provider
VITE_OBP_OAUTH2_CLIENT_ID=48ac28e9-9ee3-47fd-8448-69a62764b779
VITE_OBP_OAUTH2_CLIENT_SECRET=fOTQF7jfg8C74u7ZhSjVQpoBYvD0KpWfM5UsEZBSFFM

VITE_GOOGLE_CLIENT_ID=your-google-client-id
VITE_GOOGLE_CLIENT_SECRET=your-google-client-secret
VITE_GOOGLE_REDIRECT_URL=http://localhost:5173/api/oauth2/callback
```
**Note:** No need to specify well-known URLs - they are fetched from OBP API!
---
## Key Benefits

- Can fallback to alternative providers
- Automatic retry for failed initializations
### 4. **Extensibility**
- Strategy pattern makes adding providers trivial
- Just add environment variables
- No code changes needed
### 5. **Backward Compatibility**
- Existing single-provider mode still works
- Gradual migration path
- No breaking changes

## Troubleshooting
### Issue: No providers available
**Symptoms:**
- Provider list is empty
- Login button disabled or shows error
**Checks:**
1. Verify OBP API is running: `curl http://localhost:8080/obp/v5.1.0/well-known`
2. Check backend logs for initialization errors
3. Verify environment variables are set correctly
4. Check OIDC providers are running and accessible
**Solution:**
```bash
# Check OBP API
curl http://localhost:8080/obp/v5.1.0/well-known
# Check OBP-OIDC
curl http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration
# Restart backend with verbose logging
npm run dev:backend
```
---
### Issue: State mismatch error
**Symptoms:**
- Redirect to home with `?oauth2_error=invalid_state`
- Console shows "State mismatch (CSRF protection)"
**Causes:**
- Session not persisting between requests
- Redis not running (if using Redis sessions)
- Multiple backend instances
**Solution:**
```bash
# If using Redis, ensure it's running
redis-cli ping
# Check session secret is set
echo $SESSION_SECRET
# Clear browser cookies and try again
```
---
### Issue: Token exchange failed
**Symptoms:**
- Error after authentication: "token_exchange_failed"
- Backend logs show 401 or 400 errors
**Causes:**
- Wrong client ID or secret
- OIDC provider configuration mismatch
- Network connectivity issues
**Solution:**
```bash
# Verify client credentials in OIDC provider
# Check backend logs for detailed error
# Verify redirect URI matches exactly
```
---
### Issue: Provider shows as unavailable
**Symptoms:**
- Provider appears in list but marked as unavailable
- Red status indicator
**Causes:**
- OIDC provider is down
- Network connectivity issues
- Health check failed
**Solution:**
```bash
# Check provider is running
curl http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration
# Check backend logs for health check errors
# Wait 60 seconds for next health check
# Manually retry provider
# POST /api/oauth2/providers/{name}/retry (if implemented)
```
---
## Performance Testing
### Load Testing Login Flow
Test with multiple concurrent users:
```bash
# Install Apache Bench
sudo apt-get install apache2-utils
# Test provider list endpoint
ab -n 100 -c 10 http://localhost:5173/api/oauth2/providers
# Expected: < 100ms response time
```
### Health Check Performance
Monitor health check impact:
```bash
# Watch backend logs during health checks
tail -f backend.log | grep "health check"
# Expected: Health checks complete in < 5 seconds
```
---
## Security Testing
### Test PKCE Implementation
Verify PKCE code challenge:
1. Start login flow
2. Capture authorization URL
3. Verify `code_challenge` and `code_challenge_method=S256` present
### Test State Validation
Verify CSRF protection:
1. Capture callback URL with state
2. Modify state parameter
3. Verify callback is rejected
### Test Token Security
Verify tokens are not exposed:
1. Check tokens are not in URL parameters
2. Check tokens are not logged in console
3. Check tokens are in httpOnly cookies or session only

### HOW IT WORKS ###
# 1. Backend fetches provider list from OBP API: GET /obp/v5.1.0/well-known
# 2. OBP API returns available providers with their .well-known URLs
# 3. Backend matches providers with credentials configured above
# 4. Only providers with both (API registration + credentials) will be available
# 5. Users see provider selection if 2+ providers configured (or auto-login if only 1)

/**
* OAuth2 Callback Controller
*
* Handles the OAuth2/OIDC callback from the identity provider.
* This controller receives the authorization code and state parameter
* after the user authenticates with the OIDC provider.
*
* The OAuth2CallbackMiddleware handles:
* - State validation (CSRF protection)
* - Authorization code exchange for tokens
* - User info retrieval
* - Session storage
* - Redirect to original page
*
* Endpoint: GET /oauth2/callback
*
* Query Parameters (from OIDC provider):
* - code: Authorization code to exchange for tokens
* - state: State parameter for CSRF validation
* - error (optional): Error code if authentication failed
* - error_description (optional): Human-readable error description
*
* Flow:
* OIDC Provider → /oauth2/callback?code=XXX&state=YYY
* → OAuth2CallbackMiddleware → Original Page (with authenticated session)
*
* Success Flow:
* 1. Validate state parameter
* 2. Exchange authorization code for tokens (access, refresh, ID)
* 3. Fetch user information from UserInfo endpoint
* 4. Store tokens and user data in session
* 5. Redirect to original page or home
*
* Error Flow:
* 1. Parse error from query parameters
* 2. Display user-friendly error page
* 3. Allow user to retry authentication
*
* @example
* // Successful callback URL from OIDC provider
* http://localhost:5173/oauth2/callback?code=abc123&state=xyz789
*
* // Error callback URL from OIDC provider
* http://localhost:5173/oauth2/callback?error=access_denied&error_description=User%20cancelled
