Closes #1640 Add a standalone AWS IAM Query API implementation for managing IAM users through standard AWS SDKs and the AWS CLI. Server usage Start the IAM server with internal file-backed storage: mkdir -p /tmp/versitygw-iam ./versitygw --port 127.0.0.1:7070 --access user --secret pass iam --dir /tmp/versitygw-iam Start the IAM server with Vault KV v2 storage using AppRole: VGW_IAM_VAULT_ROLE_SECRET=<role-secret> ./versitygw --port 127.0.0.1:7070 --access user --secret pass iam --vault-endpoint-url http://127.0.0.1:8200 --vault-auth-method approle --vault-role-id <role-id> --vault-mount-path kv --vault-secret-storage-path iam Vault authentication also supports root tokens, separate authentication and secret-storage namespaces, custom mount paths, server certificate validation, and mutual TLS client certificates. Configure the AWS CLI credentials used by the IAM server: export AWS_ACCESS_KEY_ID=user export AWS_SECRET_ACCESS_KEY=pass export AWS_DEFAULT_REGION=us-east-1 Implemented IAM actions CreateUser creates an IAM user with an AWS-compatible ARN, generated AIDA user ID, creation timestamp, optional path, and tags. It validates usernames, paths, tag limits, reserved tag prefixes, duplicate tag keys, and existing users. aws --endpoint-url http://127.0.0.1:7070 iam create-user --user-name bob aws --endpoint-url http://127.0.0.1:7070 iam create-user --user-name bob --path /engineering/ --tags Key=team,Value=storage GetUser returns a stored user or the root identity when requested without a username through the IAM Query API. aws --endpoint-url http://127.0.0.1:7070 iam get-user --user-name bob ListUsers returns users in deterministic username order and supports path filtering, marker-based pagination, and MaxItems limits. aws --endpoint-url http://127.0.0.1:7070 iam list-users aws --endpoint-url http://127.0.0.1:7070 iam list-users --path-prefix /engineering/ --max-items 100 UpdateUser updates the username and/or path, recalculates the user ARN, and rejects conflicts with existing users. aws --endpoint-url http://127.0.0.1:7070 iam update-user --user-name bob --new-user-name robert --new-path /platform/ DeleteUser permanently removes an IAM user and returns AWS-compatible errors for missing users. aws --endpoint-url http://127.0.0.1:7070 iam delete-user --user-name robert IAM protocol and authentication - Support the AWS IAM Query protocol version 2010-05-08 over GET and POST form requests. - Return AWS-compatible XML responses, error documents, status codes, request IDs, user metadata, and pagination fields. - Authenticate root credentials with AWS Signature Version 4 for the IAM service in us-east-1. - Support both Authorization-header and query-string SigV4 authentication. - Validate credential scope, signed headers, timestamps, clock skew, content length, signatures, and unsupported signature or session-token modes. - Add IAM-specific validation and error mapping for malformed requests, invalid actions, duplicate entities, missing users, throttling, and internal failures. Storage implementations - Add an internal JSON-backed store using iam.json and iam.json.backup with atomic temporary-file replacement, concurrent access protection, stable ordering, pagination, and persistence across restarts. - Add a Vault KV v2 store with one secret per user, CAS-based duplicate protection, permanent deletion, AppRole reauthentication, namespace support, configurable authentication and KV mounts, root-token authentication, and TLS/mTLS configuration. - Introduce a common Storer interface and require exactly one storage backend to be configured. Server and embedding support - Register the new `versitygw iam` command with environment-variable and CLI configuration for both storage backends. - Add `embedgw.RunIAMAPI` and `IAMConfig` for embedding the IAM service in Go applications. Gateway-level internal packages - Add `internal/iamstore` as a reusable generic file-backed IAM persistence engine and migrate the existing gateway internal IAM service to it. - Add `internal/sigv4auth` for shared SigV4 header and presigned-query parsing, canonical request generation, signature verification, and structured authentication errors. - Refactor the S3 authentication paths to use the shared SigV4 implementation while preserving S3-specific error responses. - Add `internal/httpctx` for shared Fiber context keys and AWS-style request ID handling. - Add `internal/routekit` for shared query, form, and header route matchers. - Add `internal/netutil` for reusable certificate storage, hostname-aware listeners, multi-address serving, TLS listeners, and UNIX socket handling. - Update the custom SigV4 signer to honor an explicitly supplied signed-header list so unrelated headers do not alter IAM signatures. Testing and CI - Add AWS IAM SDK-based integration coverage for all supported user actions, header authentication, query authentication, validation, errors, filtering, and pagination. - Split standalone IAM tests into `versitygw test iam` and retain existing gateway IAM tests under `versitygw test gw-iam`. - Add unit coverage for controllers, authentication, routing, storage, embedding, listeners, request matching, persistence, and signing behavior. - Add `runiamtests.sh` to exercise internal storage over HTTP and HTTPS plus Vault storage through AppRole. - Add a dedicated IAM functional-test workflow with a Vault service and merged runtime coverage reporting. - Include the IAM test runner in shellcheck and add the AWS IAM SDK dependency.
