enhanced_s3_server.go to enable S3 server startup with advanced IAM - Add iam_config.json with IAM configuration for integration tests - Supports JWT Bearer token authentication for S3 operations - Integrates with STS service and policy engine for authorization --- test/s3/iam/iam_config.json | 84 +++++++++++++++ weed/s3api/enhanced_s3_server.go | 169 +++++++++++++++++++++++++++++++ 2 files
