lukaszraczylo 9126c74723 December 2025 Improvements - Azure AD, Internal Networks, Startup Race Condition (#100)
* Allow internal IPs for OIDC configuration via extra flag.

Addresses issue #97

* Allow for internal IPs in OIDC configuration.

Addresses issue #97.

* feat: Add allowPrivateIPAddresses config option for internal networks

Adds a new configuration option `allowPrivateIPAddresses` that allows
OIDC provider URLs to use private IP addresses (10.x.x.x, 172.16-31.x.x,
192.168.x.x). This is useful for internal deployments where Keycloak or
other OIDC providers run on private networks without DNS resolution.

Security considerations:
- Loopback addresses (127.0.0.1, localhost, ::1) remain blocked
- Link-local addresses (169.254.x.x) remain blocked
- Default is false (secure by default)

Fixes #97

* feat: Support non-email user identifiers for Azure AD

Add userIdentifierClaim configuration option to support Azure AD users
without email addresses. This allows using alternative JWT claims like
"sub", "oid", "upn", or "preferred_username" for user identification.

- Default behavior uses "email" claim (backward compatible)
- Falls back to "sub" claim if configured claim is missing
- allowedUsers matches against the configured claim value
- allowedUserDomains only applies when using email-based identification

Fixes #95

* Race condition on traefik pod startup

When the plugin initializes and calls GetMetadataWithRecovery():

1. Checks cache first (if metadata is cached, returns immediately)
2. Creates a retry executor with startup-optimized settings (10 attempts, 1s delays)
3. Attempts to fetch metadata from the OIDC provider
4. If the fetch fails with a retryable error (connection refused, EOF, TLS/certificate errors, Traefik default cert), it waits and retries
5. After 10 attempts or on a non-retryable error, returns the error

This allows the plugin to handle the race condition where:
- Traefik initializes the plugin before routes are established
- Traefik serves its default certificate before loading real ones
- The OIDC provider pod isn't fully ready yet

Fixes issue #90

1. Checks cache first (if metadata is cached, returns immediately)
2. Creates a retry executor with startup-optimized settings (10 attempts, 1s delays)

4. If the fetch fails with a retryable error (connection refused, EOF, TLS/certificate errors, Traefik default cert), it waits and retries
5. After 10 attempts or on a non-retryable error, returns the error

This allows the plugin to handle the race condition where:
- Traefik initializes the plugin before routes are established
- Traefik serves its default certificate before loading real ones
- The OIDC provider pod isn't fully ready yet

Fixes issue #90

* Headers too big and 431 responses

Added new option `minimalHeaders` to reduce the size of forwarded headers from the auth middleware to backend services.

  - When minimalHeaders: false (default): All headers are forwarded as before
    - X-Forwarded-User (always set)
    - X-Auth-Request-Redirect
    - X-Auth-Request-User
    - X-Auth-Request-Token (the large ID token)
    - X-User-Groups, X-User-Roles (if configured)
  - When minimalHeaders: true: Reduces header overhead
    - X-Forwarded-User (always set)
    - X-User-Groups, X-User-Roles (still forwarded if configured)
    - Custom templated headers (still processed)
    - Skipped: X-Auth-Request-Token, X-Auth-Request-User, X-Auth-Request-Redirect

Fixes issues #64 and #86

lukaszraczylo a750c4f5b9 Size computation for allocation may overflow (#99)
* Size computation for allocation may overflow

Performing calculations involving the size of potentially large strings or slices can result in an overflow (for signed integer types) or a wraparound (for unsigned types). An overflow causes the result of the calculation to become negative, while a wraparound results in a small (positive) number.

lukaszraczylo 66b9ed0861 Reauthentication + redis fix
When introspection explicitly returns that a token is inactive/revoked/expired, the plugin now properly triggers re-authentication or refresh instead of falling back to ID token validation. This fixes the functional issue where users
weren't being redirected to re-authenticate.
Redis change ensures that when the caller's context is cancelled (e.g., the 200ms timeout in UniversalCache.Get()), the operation aborts quickly instead of continuing with retries.

Explicit domain for session cookies. This is important for multi-subdomain setups
Explicit domain for session cookies. This is important for multi-subdomain setups
and reverse proxy deployments to ensure consistent cookie handling.
When set, all session cookies will use this domain. When not set, the domain
is auto-detected from the request headers (X-Forwarded-Host or Host).
Use a leading dot for subdomain-wide cookies (e.g., ".example.com" allows
cookies to be shared between app.example.com, api.example.com, etc.).
Use a specific domain for host-only cookies (e.g., "app.example.com" restricts
cookies to that exact domain).
This setting is crucial to prevent authentication issues like "CSRF token missing
in session" errors that can occur when cookies are created with inconsistent domains.
Examples:
- ".example.com" - Allows all subdomains to share cookies
- "app.example.com" - Restricts cookies to this specific host
Default: "" (auto-detected from request headers)
required: false
cookiePrefix:
type: string
description: |
Custom prefix for session cookie names. This is essential for running multiple
middleware instances with different authorization requirements on the same domain.
By default, all middleware instances use the same cookie names (_oidc_raczylo_m,
_oidc_raczylo_a, etc.), which means they share session state. When you have
multiple instances with different access restrictions (e.g., one for general users
and one for admins), this session sharing can lead to authorization bypass issues.
Setting a unique cookiePrefix for each middleware instance ensures complete
session isolation, preventing users authenticated via one middleware from
automatically gaining access to routes protected by a different middleware.
The prefix is prepended to all session cookie names:
- Main session cookie: {prefix}m
- Access token cookie: {prefix}a
- Refresh token cookie: {prefix}r
- ID token cookie: {prefix}id
Examples:
- "_oidc_userauth_" - For general user authentication middleware
- "_oidc_adminauth_" - For admin-only authentication middleware
- "_oidc_api_" - For API-specific authentication middleware
Security Note: Use different cookie prefixes AND different sessionEncryptionKey
values for each middleware instance to ensure complete isolation.

sessionMaxAge:
type: integer
description: |
Maximum session age in seconds before requiring re-authentication.
This setting controls how long a user's authentication session remains valid
before they must authenticate again through the OIDC provider. The session
age is tracked from the initial authentication time (created_at).
When a session exceeds this age:
- The session is cleared and invalidated
- The user is redirected to re-authenticate
- All session cookies are removed
Use Cases:
- High-security applications: Use shorter durations (e.g., 3600 = 1 hour)
- Standard applications: Default 24 hours balances security and UX
- Long-lived sessions: Extend for applications accessed infrequently
(e.g., 604800 = 7 days, 2592000 = 30 days)
Security Considerations:
- Shorter sessions provide better security but require more frequent logins
- Longer sessions improve user experience but increase security risk
- Consider your application's security requirements and user access patterns
- This is independent of token refresh - tokens can be refreshed during the session
Common Values:
- 3600 (1 hour) - High security applications
- 28800 (8 hours) - Working day session
- 86400 (24 hours) - Default, balances security and convenience
- 604800 (7 days) - Weekly session for less frequently accessed apps
- 2592000 (30 days) - Monthly session for infrequently used applications

OIDC providers are publicly accessible.
Enable this option when:
- Your OIDC provider (e.g., Keycloak) runs on an internal network with private IPs

IMPORTANT: Template Escaping
If you encounter the error "can't evaluate field AccessToken in type bool" when
starting Traefik, this means Traefik is trying to evaluate the template expressions
before passing them to the plugin. To fix this, you need to escape the templates
using one of these methods:
before passing them to the plugin.
1. Use YAML literal style (recommended):
headers:
- name: "Authorization"
value: |
Bearer {{.AccessToken}}
SOLUTION: You must escape the template expressions using double curly braces:
2. Use single quotes:
headers:
- name: "Authorization"
value: 'Bearer {{.AccessToken}}'
headers:
- name: "Authorization"
value: "Bearer {{{{.AccessToken}}}}"
3. For inline double quotes, escape the braces:
headers:
- name: "Authorization"
value: "Bearer {{"{{.AccessToken}}"}}"
This is the only reliable method that works consistently. Here's why:
- The YAML parser converts {{{{ → {{ and }}}} → }}
- Result: Bearer {{.AccessToken}} reaches the Go template engine correctly
- Other methods (YAML literal style, single quotes) do NOT work reliably
Examples:
- name: "X-User-Email", value: "{{.Claims.email}}"
- name: "Authorization", value: "Bearer {{.AccessToken}}"
- name: "X-User-Roles", value: "{{range $i, $e := .Claims.roles}}{{if $i}},{{end}}{{$e}}{{end}}"

Optional Redis cache configuration for multi-replica deployments.
When running multiple Traefik instances, Redis provides shared caching to:
- Prevent JTI replay detection false positives across replicas
- Share token verification results between instances
- Maintain consistent session state across the cluster
- Improve performance by reducing redundant OIDC provider calls
Features:
- Automatic failover to memory-only mode when Redis is unavailable
- Circuit breaker pattern for resilience against Redis failures
- Health checking with automatic recovery
- Multiple cache modes: redis-only, hybrid (L1 memory + L2 Redis), memory-only
- Configurable timeouts and connection pooling
- TLS support for secure Redis connections
The middleware gracefully handles Redis failures by falling back to in-memory
caching, ensuring your authentication flow continues even during Redis outages.

**Recommendation**: For single-instance deployments, leave this setting at `false` (default) to maintain replay attack protection. For multi-replica deployments, use the Redis cache backend for proper replay detection across all instances.
## Redis Cache (Optional)
The plugin supports optional Redis caching for multi-replica deployments. This solves issues with JTI replay detection and session management when running multiple Traefik instances behind a load balancer.
> **✨ Yaegi Compatible**: Redis support is implemented using a pure-Go RESP protocol client that works seamlessly with Traefik's Yaegi interpreter (no `unsafe` package). Full Redis functionality is available for both dynamic plugin loading and pre-compiled deployments.
### Why Use Redis Cache?
When running multiple Traefik replicas, each instance maintains its own in-memory cache for:
- JTI (JWT Token ID) replay detection
- Session data
- Token metadata
Without a shared cache, you may experience:
- False positive replay detection errors
- Session inconsistencies between replicas
- Users needing to re-authenticate when hitting different instances
### Basic Configuration
Redis is configured through Traefik's dynamic configuration (YAML, labels, etc.):
```yaml
# Enable Redis cache in your middleware configuration
redis:
enabled: true
address: "localhost:6379"
password: "your-password" # Optional
db: 0
keyPrefix: "traefikoidc:"
```
### Configuration Priority
The plugin uses the following priority for Redis configuration:
1. **Traefik Dynamic Configuration** (PRIMARY) - Configure via YAML files or Docker/Kubernetes labels
2. **Environment Variables** (FALLBACK) - Used only when not set in Traefik config
This approach allows you to manage all settings through Traefik's configuration system while maintaining backward compatibility with environment variables.
### Configuration Options
| Parameter | Description | Default | Example |
|-----------|-------------|---------|---------|
| `enabled` | Enable Redis caching | `false` | `true` |
| `address` | Redis server address | - | `redis:6379` |
| `password` | Redis password | - | `YOUR_PASSWORD` |
| `db` | Database number | `0` | `1` |
| `keyPrefix` | Key prefix for namespacing | `traefikoidc:` | `myapp:` |
| `cacheMode` | Cache mode: `redis`, `hybrid`, `memory` | `redis` | `hybrid` |
| `poolSize` | Connection pool size | `10` | `20` |
| `connectTimeout` | Connection timeout (seconds) | `5` | `10` |
| `readTimeout` | Read timeout (seconds) | `3` | `5` |
| `writeTimeout` | Write timeout (seconds) | `3` | `5` |
| `enableTLS` | Enable TLS | `false` | `true` |
| `tlsSkipVerify` | Skip TLS verification | `false` | `true` |
| `enableCircuitBreaker` | Circuit breaker for failures | `true` | `true` |
| `circuitBreakerThreshold` | Failures before circuit opens | `5` | `10` |
| `circuitBreakerTimeout` | Circuit reset timeout (seconds) | `60` | `30` |
| `enableHealthCheck` | Periodic health checks | `true` | `true` |
| `healthCheckInterval` | Health check interval (seconds) | `30` | `60` |
### Environment Variables (Fallback)
If not configured through Traefik, these environment variables can be used as fallback:
- `REDIS_ENABLED` - Enable Redis cache
- `REDIS_ADDRESS` - Redis server address
- `REDIS_PASSWORD` - Redis password
- `REDIS_DB` - Database number
- `REDIS_KEY_PREFIX` - Key prefix
- `REDIS_CACHE_MODE` - Cache mode
- `REDIS_POOL_SIZE` - Connection pool size
- `REDIS_CONNECT_TIMEOUT` - Connection timeout
- `REDIS_READ_TIMEOUT` - Read timeout
- `REDIS_WRITE_TIMEOUT` - Write timeout
- `REDIS_ENABLE_TLS` - Enable TLS
- `REDIS_TLS_SKIP_VERIFY` - Skip TLS verification
### Cache Modes
The plugin supports three cache modes:
- **memory** (default): In-memory cache only, suitable for single-instance deployments
- **redis**: Redis-only cache, all data stored in Redis
- **hybrid**: Two-tier caching with local memory cache + Redis backend for optimal performance
### Example Configurations

## Dynamic Client Registration (RFC 7591)
The middleware supports **OIDC Dynamic Client Registration** (RFC 7591), allowing automatic client registration with OIDC providers without manual pre-registration. This is useful for:
- **Multi-tenant deployments**: Automatically register clients per tenant
- **Development environments**: Quick setup without manual OAuth app creation
- **Self-service integrations**: Allow applications to self-register
### How It Works
1. When enabled, the middleware discovers the `registration_endpoint` from the provider's `.well-known/openid-configuration`
2. If no `clientID` is configured, it automatically registers a new client with the provider
3. The registered `client_id` and `client_secret` are cached and optionally persisted to a file
4. Subsequent requests use the registered credentials
### Configuration

### Provider Support
DCR support varies by provider:
| Provider | DCR Support | Notes |
|----------|-------------|-------|
| Keycloak | ✅ Full | Enable in realm settings |
| Auth0 | ✅ Full | Requires Management API token |
| Okta | ✅ Full | Enable Dynamic Client Registration |
| Azure AD | ⚠️ Limited | App Registration API instead |
| Google | ❌ No | Manual registration required |
| AWS Cognito | ❌ No | Manual registration required |
### Security Considerations
1. **HTTPS Required**: Registration endpoints must use HTTPS (except localhost for development)
2. **Initial Access Token**: Recommended for production to prevent unauthorized registrations
3. **Credential Persistence**: If enabled, ensure the credentials file has appropriate permissions (0600)
4. **Secret Expiration**: Monitor `client_secret_expires_at` and handle rotation if needed
### Example: Keycloak with DCR
```yaml
dynamicClientRegistration:
enabled: true
clientMetadata:
redirect_uris:
- "https://myapp.example.com/oauth2/callback"
client_name: "My App - Production"
application_type: "web"
grant_types:

**Important**: The `cookieDomain` parameter is crucial when running behind a reverse proxy or when your application serves multiple subdomains. Without it, cookies may be created with inconsistent domains, leading to authentication issues like "CSRF token missing in session" errors.
### With Multiple Middleware Instances (Session Isolation)
When running multiple middleware instances with different authorization requirements (e.g., one for general users and one for admins), you must use different `cookiePrefix` values to prevent session sharing between instances:
```yaml
# Middleware for general user authentication
apiVersion: traefik.io/v1alpha1
kind: Middleware
metadata:
name: oidc-userauth
namespace: traefik
spec:
plugin:
traefikoidc:
providerURL: https://auth.example.com

clientSecret: your-client-secret
sessionEncryptionKey: user-key-at-least-32-bytes-long
callbackURL: /oauth2/callback
cookiePrefix: "_oidc_userauth_" # Unique prefix for this instance

clientID: your-client-id
clientSecret: your-client-secret
sessionEncryptionKey: admin-key-at-least-32-bytes-long # Different encryption key
callbackURL: /oauth2/admin/callback # Different callback URL
cookiePrefix: "_oidc_adminauth_" # Different prefix for isolation
allowedUsers: # Restricted to specific admin users
- admin@example.com
- superadmin@example.com
```
**Security Note**: When running multiple instances, ensure you use:
1. **Different `cookiePrefix`** values to prevent cookie name collisions
2. **Different `sessionEncryptionKey`** values for complete session isolation
3. **Different `callbackURL`** paths to avoid routing conflicts
This configuration prevents authorization bypass issues where a user authenticated via the general middleware could access admin-protected routes. See [issue #87](https://github.com/lukaszraczylo/traefikoidc/issues/87) for more details.
### With Extended Session Duration
For applications that users access infrequently (weekly or monthly), you can extend the session duration beyond the default 24 hours to reduce authentication friction:
```yaml
apiVersion: traefik.io/v1alpha1
kind: Middleware
metadata:
name: oidc-long-session
namespace: traefik
spec:
plugin:
traefikoidc:

clientID: your-client-id
clientSecret: your-client-secret
sessionEncryptionKey: your-key-at-least-32-bytes-long
callbackURL: /oauth2/callback
sessionMaxAge: 604800 # 7 days (in seconds)
# Other common values:
# 259200 - 3 days
# 604800 - 7 days
# 1209600 - 14 days
# 2592000 - 30 days
```
**Security Note**: Longer session durations improve user experience but increase security risk. Consider your application's security requirements:
- **High-security apps**: Use shorter sessions (3600 = 1 hour)
- **Standard apps**: Default 24 hours balances security and UX
- **Low-frequency access apps**: Extend to 7-30 days for better UX

## Advanced Configuration
### Session Management
The middleware uses encrypted cookies to manage user sessions. The `sessionEncryptionKey` must be at least 32 bytes long and should be kept secret.
### PKCE Support
The middleware supports PKCE (Proof Key for Code Exchange), which is an extension to the authorization code flow to prevent authorization code interception attacks. When enabled via the `enablePKCE` option, the middleware will generate a code verifier for each authentication request and derive a code challenge from it. The code verifier is stored in the user's session and sent during the token exchange process.
PKCE is recommended when:
- Your OIDC provider supports it (most modern providers do)
- You need an additional layer of security for the authorization code flow
- You're concerned about potential authorization code interception attacks
Note that not all OIDC providers support PKCE, so check your provider's documentation before enabling this feature.
### Session Duration and Token Refresh
This middleware aims to provide long-lived user sessions, typically up to 24 hours, by utilizing OIDC refresh tokens.
**How it works:**
- When a user authenticates, the middleware requests an access token and, if available, a refresh token from the OIDC provider.
- The access token usually has a short lifespan (e.g., 1 hour).
- Before the access token expires (controlled by `refreshGracePeriodSeconds`), the middleware uses the refresh token to obtain a new access token from the provider without requiring the user to log in again.
- This process repeats, allowing the session to remain valid for as long as the refresh token is valid (often 24 hours or more, depending on the provider).
**Provider-Specific Considerations (e.g., Google):**
- Some providers, like Google, issue short-lived access tokens (e.g., 1 hour) and require specific configurations for long-term sessions.
- To enable session extension beyond the initial token expiry with Google and similar providers, the middleware automatically includes the `offline_access` scope in the authentication request. This scope is necessary to obtain a refresh token.
- For Google specifically, the middleware also adds the `prompt=consent` parameter to the initial authorization request. This ensures Google issues a refresh token, which is crucial for extending the session.
- If a refresh attempt fails (e.g., the refresh token is revoked or expired), the user will be required to re-authenticate. The middleware includes enhanced error handling and logging for these scenarios.
- Ensure your OIDC provider is configured to issue refresh tokens and allows their use for extending sessions. Check your provider's documentation for details on refresh token validity periods.
### Google OAuth Compatibility Fix
The middleware includes a specific fix for Google's OAuth implementation, which differs from the standard OIDC specification in how it handles refresh tokens:
- **Issue**: Google does not support the standard `offline_access` scope for requesting refresh tokens and instead requires special parameters.
- **Automatic Solution**: The middleware detects Google as the provider based on the issuer URL and:
- Uses `access_type=offline` query parameter instead of the `offline_access` scope
- Adds `prompt=consent` to ensure refresh tokens are consistently issued
- Properly handles token refresh with Google's implementation
You do not need any special configuration to use Google OAuth - just set `providerURL` to `https://accounts.google.com` and the middleware will automatically apply the proper parameters.
For detailed information on the Google OAuth fix, see the [dedicated documentation](docs/google-oauth-fix.md).
### Token Caching and Blacklisting
The middleware automatically caches validated tokens to improve performance and maintains a blacklist of revoked tokens.
### Templated Headers
The middleware supports setting custom HTTP headers with values templated from OIDC claims and tokens. This allows you to pass authentication information to downstream services in a flexible, customized format.
@@ -1320,12 +1675,39 @@ headers:
When a user is authenticated, the middleware sets the following headers for downstream services:
- `X-Forwarded-User`: The user's email address
- `X-Forwarded-User`: The user's email address (always set)
- `X-User-Groups`: Comma-separated list of user groups (if available)
- `X-User-Roles`: Comma-separated list of user roles (if available)
- `X-Auth-Request-Redirect`: The original request URI
- `X-Auth-Request-User`: The user's email address
- `X-Auth-Request-Token`: The user's access token
- `X-Auth-Request-Token`: The user's ID token (can be large)
#### Minimal Headers Mode
If your downstream services return **"431 Request Header Fields Too Large"** errors, you can enable minimal headers mode to reduce header overhead:
```yaml
http:
middlewares:
my-auth:
plugin:
traefikoidc:
minimalHeaders: true
# ... other config
```
When `minimalHeaders: true` is set:
- **Only forwards**: `X-Forwarded-User`
- **Skips**: `X-Auth-Request-Token` (the full ID token - often the largest header), `X-Auth-Request-User`, `X-Auth-Request-Redirect`
- **Still forwards**: `X-User-Groups` and `X-User-Roles` (if configured)
- **Still processes**: Custom templated headers
This is particularly useful when:
- Your ID tokens are large (many claims, long group lists)
- Downstream services have limited header buffer sizes (default 8KB in many servers)
- You don't need the full token forwarded to backend services
See [GitHub Issue #64](https://github.com/lukaszraczylo/traefikoidc/issues/64) for details.
### Security Headers
@@ -1449,32 +1831,6 @@ GitLab supports OIDC for both GitLab.com and self-hosted instances.
* **Scopes**: Use `user:email`, `read:user` for basic profile access
* **Detection**: Auto-detected from `github.com` in issuer URL
### Azure AD (Microsoft Entra ID)
Azure AD generally works well with standard OIDC configurations.
* **ID Token Claims**: Azure AD typically includes standard claims like `email`, `name`, `preferred_username`, and `oid` (Object ID) in the ID Token by default when `openid profile email` scopes are requested.
* **Group Claims**: To include group claims in the ID Token, you need to configure this in the Azure AD application registration:
* Go to your App Registration -> Token configuration -> Add groups claim.
* You can choose which types of groups (Security groups, Directory roles, All groups) to include.
* Be aware of the "overage" issue: If a user is a member of too many groups, Azure AD will send a link to fetch groups instead of embedding them. This plugin currently expects group claims to be directly in the ID token. For users with many groups, consider alternative role/permission management strategies.
* The claim name for groups is typically `groups`.
* **Optional Claims**: You can add other optional claims via the "Token configuration" section of your App Registration. Ensure these are configured for the ID token.
* **Endpoints**: The `providerURL` should be `https://login.microsoftonline.com/{your-tenant-id}/v2.0`. The plugin will auto-discover the necessary endpoints.
* **Optimization**: Ensure your application manifest in Azure AD is configured for the desired token version (v1.0 or v2.0). This plugin works with v2.0 endpoints.
### Google Workspace / Google Cloud Identity
Google's OIDC implementation is well-supported.
* **Optimal Configuration**: The plugin automatically handles Google-specific requirements, such as using `access_type=offline` and `prompt=consent` to ensure refresh tokens are issued for long-lived sessions. You do not need to add `offline_access` to scopes.
* **ID Token Claims**: Google includes standard claims like `email`, `sub`, `name`, `given_name`, `family_name`, `picture` in the ID Token by default with `openid profile email` scopes.
* **Hosted Domain (hd claim)**: If you are using Google Workspace and want to restrict access to users within your organization's domain, Google includes an `hd` (hosted domain) claim in the ID Token. You can use this with the `allowedUserDomains` setting or for custom header logic.
* **Best Practices**:
* Use the `providerURL`: `https://accounts.google.com`.
* Ensure your OAuth consent screen in Google Cloud Console is configured correctly and published. For production, it should be "External" and in "Production" status. "Testing" status limits refresh token lifetime.
* Refer to the [Google OAuth Compatibility Fix](#google-oauth-compatibility-fix) section for more details on how the plugin handles Google's specifics.

- When using environment variable syntax like `${OIDC_ENCRYPTION_SECRET_API}` in Traefik configuration, the plugin fails with "invalid handler type: \<nil\>" error
- This is a **Traefik-side issue**, not a plugin bug. Traefik uses reserved environment variables starting with `TRAEFIK_API_*` for its internal API configuration, and the "API" substring in user-defined variable names may interfere with Traefik's environment variable processing
- **Workaround**: Avoid using "API" as a substring in environment variable names. Use alternatives like:
- `${OIDC_ENCRYPTION_SECRET_SVC}` instead of `${OIDC_ENCRYPTION_SECRET_API}`
- `${OIDC_ENCRYPTION_SECRET_SERVICE}`
- `${OIDC_ENCRYPTION_SECRET_BACKEND}`
- Any name that doesn't contain the literal substring "API"

### Internal Network Deployment
If your Keycloak instance runs on an internal network with private IP addresses (e.g., Docker networks, Kubernetes internal services), set `allowPrivateIPAddresses: true`:
```yaml
traefikoidc:
providerUrl: "https://192.168.1.100:8443/auth/realms/your-realm" # Private IP
allowPrivateIPAddresses: true # Required for private IP addresses
clientId: "your-client-id"
clientSecret: "your-client-secret"
# ... other config
```
> **Security Warning**: Only enable `allowPrivateIPAddresses` in trusted network environments where you control the OIDC provider. This setting reduces SSRF protection.

```
## Test Patterns Used
### 1. Table-Driven Tests
Used for testing multiple scenarios with similar structure.
### 2. Subtests (t.Run)
Organized test cases into logical groups with clear names.
### 3. Parallel Tests
Tests marked with `t.Parallel()` for faster execution.
### 4. Test Fixtures
Reusable setup functions for common test data.
### 5. Mocking
- `miniredis` for Redis operations
- Mock functions for callbacks and health checks
### 6. Assertion Helpers
Using `testify/assert` and `testify/require` for clear assertions.

## Performance Benchmarks
Benchmarks included for:
- Cache operations (Set, Get, Delete)
- Circuit breaker execution
- Health check operations
- Concurrent access patterns
- Large datasets (10,000+ items)
## Dependencies
### Testing Libraries
- `github.com/stretchr/testify` - Assertions and test utilities
- `github.com/alicebob/miniredis/v2` - In-memory Redis mock
- `github.com/redis/go-redis/v9` - Redis client
### Why Miniredis?
- **No external dependencies** - No Redis server required
- **Fast** - In-memory, perfect for unit tests
- **Full Redis API** - Supports all operations we need
- **Time manipulation** - FastForward for TTL testing
- **Error simulation** - Test failure scenarios
## Future Enhancements
### Planned Tests
1. Hybrid backend tests (L1/L2 cache)
2. Network partition scenarios
3. Redis cluster support
4. Persistence and recovery tests
5. Metrics and monitoring integration
### Test Infrastructure Improvements
1. Test containers for real Redis integration
2. Performance regression tracking
3. Chaos engineering tests
4. Load testing framework
## Continuous Integration
### Recommended CI Configuration
```yaml
test:
script:
- go test ./internal/cache/... -race -cover -v
- go test -run TestRedisIntegration -v
- go test ./internal/cache/... -bench=. -benchmem
```
## Maintenance Guidelines
1. **Add tests for new features** - Maintain >85% coverage
2. **Update contract tests** - When interface changes
3. **Test edge cases** - Always test error paths
4. **Document test purpose** - Clear comments explaining what each test validates
5. **Keep tests fast** - Use t.Parallel() where possible
6. **Mock external dependencies** - Use miniredis, not real Redis
## Conclusion
This comprehensive test suite provides:
- **High confidence** in cache backend correctness
- **Fast feedback** - Tests run in seconds
- **Good coverage** - 90% overall
- **Clear documentation** - Each test is well-documented
- **Maintainability** - Clear structure and patterns
The test suite ensures that the Redis cache backend feature is production-ready and reliable for multi-replica Traefik deployments with shared caching requirements.
