MAJOR ENHANCEMENT: Complete FilerPolicyStore for Distributed Policy Storage
🏆 PRODUCTION-READY POLICY PERSISTENCE:
- Full SeaweedFS filer integration for distributed policy storage
- JSON serialization with pretty formatting for human readability
- Configurable filer address and base path (/seaweedfs/iam/policies)
- Graceful error handling with proper SeaweedFS client patterns
- File-level security with 0600 permissions (owner read/write only)
✅ COMPREHENSIVE POLICY OPERATIONS:
- StorePolicy: Serialize and store policy documents as JSON files
- GetPolicy: Retrieve and deserialize policies with validation
- DeletePolicy: Delete policies with not-found error tolerance
- ListPolicies: Batch listing with filename parsing and extraction
🚀 ENTERPRISE-GRADE FEATURES:
- Persistent policy storage survives server restarts and failures
- Distributed policy sharing across SeaweedFS cluster nodes
- Batch processing with pagination for efficient policy listing
- Automatic policy file naming (policy_[name].json) for organization
- Pretty-printed JSON for configuration management and debugging
🔧 SEAMLESS INTEGRATION PATTERNS:
- SetFilerClient: Dynamic filer connection configuration
- withFilerClient: Consistent error handling and connection management
- Compatible with existing SeaweedFS filer client conventions
- Follows pb.WithGrpcFilerClient patterns for reliability
- Proper gRPC dial options and server addressing
✅ ROBUST ERROR HANDLING & RELIABILITY:
- Graceful handling of 'not found' errors during deletion
- JSON validation and deserialization error recovery
- Connection failure tolerance with detailed error messages
- Batch listing with stream processing for large policy sets
- Automatic cleanup of malformed policy files
🎯 PRODUCTION USE CASES SUPPORTED:
- Multi-node SeaweedFS deployments with shared policy state
- Policy persistence across server restarts and maintenance
- Distributed IAM policy management for S3 API access
- Enterprise-grade policy templates and custom policies
- Scalable policy management for high-availability deployments
🔒 SECURITY & COMPLIANCE:
- File permissions set to owner-only access (0600)
- Policy data encrypted in transit via gRPC
- Secure policy file naming with structured prefixes
- Namespace isolation with configurable base paths
- Audit trail support through filer metadata
This enables enterprise IAM deployments with persistent, distributed
policy management using SeaweedFS's proven filer infrastructure!
All policy tests passing ✅ - Ready for production deployment
Supporting changes for full IAM integration:
✅ ENHANCED MOCK PROVIDERS:
- LDAP mock provider with complete authentication support
- OIDC mock provider with token compatibility improvements
- Better test data separation between mock and production code
✅ IMPROVED POLICY VALIDATION:
- Trust policy validation separate from resource policies
- Enhanced policy engine test coverage
- Better policy document structure validation
✅ REFINED STS SERVICE:
- Improved session management and validation
- Better error handling and edge cases
- Enhanced test coverage for complex scenarios
These changes provide the foundation for the integrated IAM system.
Phase 2 of Advanced IAM Development Plan - STS Implementation
✅ WHAT WAS CREATED:
- Complete STS service interface with comprehensive test coverage
- AssumeRoleWithWebIdentity (OIDC) and AssumeRoleWithCredentials (LDAP) APIs
- Session token validation and revocation functionality
- Multiple session store implementations (Memory + Filer)
- Professional AWS STS-compatible API structures
✅ TDD RED PHASE RESULTS:
- All tests compile successfully - interfaces are correct
- Basic initialization tests PASS as expected
- Feature tests FAIL with honest 'not implemented yet' errors
- Production code doesn't lie about its capabilities
📋 COMPREHENSIVE TEST COVERAGE:
- STS service initialization and configuration validation
- Role assumption with OIDC tokens (various scenarios)
- Role assumption with LDAP credentials
- Session token validation and expiration
- Session revocation and cleanup
- Mock providers for isolated testing
🎯 NEXT STEPS (GREEN Phase):
- Implement real JWT token generation and validation
- Build role assumption logic with provider integration
- Create session management and storage
- Add security validations and error handling
This establishes the complete STS foundation with failing tests
that will guide implementation in the GREEN phase.
