TODO - Authentication & Authorization Integration

Status: ✅ IMPLEMENTATION COMPLETE
Version: 6.1.0
Completed: This Session

---

Summary

Successfully integrated real authentication and authorization into the botserver:

1. Created pluggable authentication system with AuthProviderRegistry
2. Integrated existing JwtManager for proper JWT token validation
3. Integrated existing ZitadelAuthProvider for external IdP support
4. Added RBAC middleware factories for permission enforcement
5. Updated AppState with auth managers
6. Updated main.rs to initialize and use new auth system

---

✅ COMPLETED - All Phases

Phase 1: Core Authentication Integration ✅

• 1.1 Create AuthProvider trait for pluggable authentication
• 1.2 Implement LocalJwtAuthProvider using existing JwtManager
• 1.3 Implement ZitadelAuthProviderAdapter wrapping existing ZitadelAuthProvider
• 1.4 Create AuthProviderRegistry to manage multiple providers
• 1.5 Update auth_middleware to use AuthProviderRegistry

Phase 2: State Integration ✅

• 2.1 Add JwtManager to AppState
• 2.2 Add ZitadelAuthProvider (optional) to AppState
• 2.3 Add RbacManager to AppState
• 2.4 Add AuthProviderRegistry to AppState
• 2.5 Update main.rs to initialize all auth components

Phase 3: RBAC Enforcement ✅

• 3.1 Create require_permission_layer middleware factory
• 3.2 Create require_role_layer middleware factory
• 3.3 Create RbacMiddlewareState for stateful RBAC checks
• 3.4 Create RbacError enum with proper HTTP responses
• 3.5 Create require_admin_middleware and require_super_admin_middleware

Phase 4: Database Integration ✅

• 4.1 RBAC seed data migration exists: 20250714000001_add_rbac_tables
• 4.2 RBAC tables defined in schema.rs

Phase 5: Verification ✅

• 5.1 Full compilation test ✅ (0 warnings, 0 errors)
• 5.2 Runtime verification ✅

Key Types

// Authentication
AuthProvider              // Trait for pluggable auth
LocalJwtAuthProvider      // JWT validation via JwtManager
ZitadelAuthProviderAdapter// OAuth2 token introspection
ApiKeyAuthProvider        // API key validation
AuthProviderRegistry      // Multi-provider orchestration
AuthProviderBuilder       // Fluent builder pattern
AuthMiddlewareState       // State for auth middleware
ExtractedAuthData         // Thread-safe auth data extraction

// Authorization
RbacMiddlewareState       // State for RBAC middleware
RbacError                 // Permission denied errors
create_permission_layer() // Factory for permission checks
create_role_layer()       // Factory for role checks

Usage Examples

Apply Permission Check to Route

use axum::middleware;
use botserver::security::{create_permission_layer, require_permission_middleware};

let protected_routes = Router::new()
    .route("/api/users", get(list_users))
    .layer(middleware::from_fn_with_state(
        create_permission_layer(rbac_manager, "users.read"),
        require_permission_middleware,
    ));

Apply Admin Check to Route

use botserver::security::require_admin_middleware;

let admin_routes = Router::new()
    .route("/api/admin/settings", post(update_settings))
    .layer(middleware::from_fn(require_admin_middleware));

What Was Fixed

Before (Placeholder)

fn validate_bearer_token_sync(token: &str) -> Result<AuthenticatedUser, AuthError> {
    let parts: Vec<&str> = token.split('.').collect();
    if parts.len() != 3 {
        return Err(AuthError::InvalidToken);
    }
    // ❌ Created random user, no real validation
    Ok(AuthenticatedUser::new(Uuid::new_v4(), "jwt-user".to_string()))
}

After (Real Implementation)

// LocalJwtAuthProvider::authenticate()
async fn authenticate(&self, token: &str) -> Result<AuthenticatedUser, AuthError> {
    let claims = self.jwt_manager
        .validate_access_token(token)  // ✅ Real JWT validation
        .map_err(|_| AuthError::InvalidToken)?;
    
    self.claims_to_user(&claims)  // ✅ Extract real user data from claims
}

Implementation Status: COMPLETE ✅
