Gates bucket listing behind an identity policy, lets browsers reach the standalone IAM API, and turns the WebUI into a dashboard for S3, IAM, or both.
**Bucket listing.** `ListBuckets` is now gated by the new `s3:ListAllMyBuckets` action, evaluated against `arn:aws:s3:::*`. The request names no bucket, so only identity policies apply — there is no resource policy to combine with, which is the same shape `CreateBucket` already had, so both now share one identity-only evaluation path. Root and admin bypass it, and backends with no identity-policy layer keep listing as before since their listing is already narrowed to the caller's own buckets. The action is IAM-only and is deliberately absent from the bucket-policy action list.
**Fixed bucket ownership.** The standalone IAM client has no per-user ownership to express — accounts are all plain users, cannot be enumerated, and access is decided by policy rather than ACL — so it now implements `auth.FixedBucketOwner` and every bucket is owned by root. Bucket creation stops resolving an owner, `ListBuckets` returns every bucket to every caller (what they may then do with one stays a per-request policy decision), and the admin `ChangeBucketOwner` reports method-not-supported. Other IAM backends are untouched.
**IAM service CORS.** `--cors-allow-origin` now applies to the `iam` command: it answers preflights and stamps the CORS headers, mirroring back the requested method and headers rather than enumerating the SigV4 header set. Without it no browser can reach the IAM API at all, so setting `--webui` without it falls back to `*` with a warning. The chart gets `iamServer.corsAllowOrigin`.
**WebUI.** New IAM pages for users, roles and OIDC providers, signing IAM/STS query-form requests directly from the browser. Navigation is capability-gated rather than role-gated: on sign-in the session probes the S3, admin and IAM endpoints independently and each page shows only what those credentials actually reach, so one build serves an IAM-only dashboard, an S3-only dashboard, and a combined one. The login page takes an optional IAM endpoint, seeded from the new `--webui-iam-gateways` (chart: `webui.iamGateways`) — never auto-detected, since the IAM service is a separate process. The WebUI can also be hosted by `versitygw iam` itself, for deployments with no S3 gateway behind it.
**The admin API is ignored once an IAM endpoint is in play.** The IAM service is then the user directory and bucket ownership is fixed, which leaves the admin API no job: the session is given no admin endpoint at all, its login field is hidden, `users.html` redirects to its IAM counterpart, and every admin-only surface stays off screen. Dashboard and Buckets remain available to any S3 session in such a deployment, running on the S3 and IAM APIs alone and surfacing each denial per action instead of redirecting.
Also fixes two WebUI bugs: embedded assets went out with a zero modification time and no `Cache-Control`, so browsers treated them as fresh for centuries and an upgraded gateway served new HTML against stale JS — they now revalidate against an ETag; and the login page's advanced-options section clipped its last field, since it animated to a height named in the stylesheet rather than the one it measures now.
**Usage**
IAM-only dashboard, served by the IAM service:
versitygw iam --port :7076 --webui :8080 --cors-allow-origin http://localhost:8080/
IAM + S3, dashboard served by the IAM service — point it at the gateway with `--webui-gateways`, and let the gateway accept the dashboard's origin:
versitygw iam --port :7076 --webui :8080 --webui-gateways http://localhost:7070/ --cors-allow-origin http://localhost:8080/
versitygw --port :7070 --cors-allow-origin http://localhost:8080/ posix /data
IAM + S3, dashboard served by the S3 gateway — point it at the IAM service with `--webui-iam-gateways`, and let the IAM service accept the dashboard's origin:
versitygw --port :7070 --webui :8080 --webui-iam-gateways http://localhost:7076/ posix /data
versitygw iam --port :7076 --cors-allow-origin http://localhost:8080/
This adds a new iamServer Deployment, split public and private Services, a PersistentVolumeClaim, and cert-manager Certificate resources so the standalone versitygw iam API server can be deployed directly from this chart, independently scalable from the S3 gateway and backed by either internal file storage or HashiCorp Vault, with Vault auth credentials and Vault TLS material kept in separate Kubernetes secrets. The gateway side gains iam.type=standalone client wiring that reaches the IAM service over its private mTLS endpoint, with certificates supplied either through an existing secret or auto-provisioned via cert-manager using a shared CA-type issuer so both peers can verify each other from their own certificate's ca.crt, and the chart auto-targets the in-chart service when no external endpoint is configured. gateway.logLevel and iamServer.logLevel replace the old boolean debug flag with the silent, debug, and unsafe levels the binary now supports, docker-entrypoint.sh gained iam as a recognized VGW_BACKEND value so the new deployment can start through the existing entrypoint, NetworkPolicy resources were corrected to use proper peer lists and to default to deny instead of allow when no ingress rules are configured, pod and Deployment selector labels were separated between the gateway and the IAM server to prevent them from matching each other's Services, and a battery of template time validation guards was added to fail fast on invalid combinations such as multiple replicas against the internal file store or a missing certificate for a TCP private endpoint, together with expanded helm lint coverage in CI for these new configurations.
Implements the `AssumeRoleWithWebIdentity` and `GetCallerIdentity` STS actions, letting callers exchange an external OIDC token for temporary credentials scoped to an IAM role. Token handling covers JWT claim parsing, issuer/audience resolution (including `azp` override semantics), JWKS fetching and caching with `singleflight`-deduplicated refresh, and rate-limited forced refresh on unrecognized `kid` values. OIDC provider thumbprint fetching now performs a real TLS handshake verified against the system trust store and the provider hostname (previously `InsecureSkipVerify`), since the observed certificate is persisted as a long-lived trust anchor rather than used once and discarded; all discovery-document and JWKS fetches go through an SSRF-safe HTTP client with bounded redirects and response size.
Adds policy `Condition` block evaluation, supporting `String`, `Numeric`, `Date`, `Bool`, `BinaryEquals`, and `IpAddress` operators along with their `IfExists`/`Not` variants and `ForAllValues`/`ForAnyValues` set qualifiers, plus policy variable substitution (e.g. `${aws:username}`) in supported operators. Adds identity-based inline policy evaluation and a new IAM authorization middleware that authorizes each request against action, resource, and condition context together, applying the session-policy-intersects-role-policy semantics for assumed-role sessions.
Adds a new debug logger `--log-level` flag (`silent`/`debug`/`unsafe`), along with a tree-based XML masker that redacts secrets and tokens at the property level in logged request/response bodies instead of skipping the whole body. The old `--debug/VGW_DEBUG` flag is kept as a deprecated alias for `--log-level=debug`, printing a console warning that points users at `--log-level` for finer-grained control.
Fixes a Vault storage bug where CAS (check-and-set) writes always read the current document version as 0 because `kvVersion` asserted metadata as `float64` while the Vault client actually returns `json.Number`, causing every write past the first to be rejected as a concurrent modification. Also adds a constant-time `SecureCompare` for signature/token comparisons in sigv4 auth.
Adds an integration test suite (`iam_access_control.go`) covering IAM access control across user, role, and session identities.
This change is needed to expose the admin API and WebUI through standard
Kubernetes Ingress resources instead of only through service access or Gateway
API routes. It adds configurable ingress blocks in values.yaml, and renders
dedicated ingress objects for admin and webui when enabled.
Also update corsAllowOrigin comment.

The Helm chart now supports dedicated sidecar metadata and versioning
directories alongside the primary data directory. For POSIX deployments,
users can configure a sidecar metadata path without forcing backend flags
through a single args string, and POSIX or ScoutFS deployments can expose
a persistent versioning directory through the chart as well.
This makes the chart usable for filesystem-backed setups that need
sidecar metadata storage or object versioning support, while keeping the
configuration aligned with the existing persistent data and IAM layout.
The chart version is bumped to reflect the new deployment behavior.

Add error document serving, routing rules, and integration tests
Implement Features 1 and 2 of S3 static website hosting:
- WebsiteErrorDocument controller wrapper intercepts 4xx errors on
website-enabled buckets and serves the configured error document or
evaluates post-request routing rules (error code match redirects)
- ResolveWebsiteIndex middleware now caches parsed WebsiteConfiguration
in context, handles RedirectAllRequestsTo, evaluates pre-request
routing rules (key prefix match redirects), and rewrites directory
keys for index document
- MatchPreRequestRule and MatchPostRequestRule methods on
WebsiteConfiguration for routing rule evaluation
- 14 unit tests for routing rule matching
- 7 integration tests covering error document, routing rules,
redirect-all, and index document behavior
