enterprise

Commercial license, not AGPLv3 — see /CLAUDE.md's licensing boundary. SSO (OIDC/SAML), tenant provisioning, and RBAC. Nothing in /agent, /ingest, /storage, /api, /web core, or /cli imports from this module — confirmed by hack/check-tenant-boundary.sh, run in CI. enterprise/ supplies tenant-scoped implementations of core's already-shipped api/querylang/executor.SQLRunner/ SearchClient interfaces rather than core growing tenant awareness — see /docs/phase-4-isolation-design.md for why.

Status

What's built and wired end-to-end. Verification status varies by piece -- internal/audit was confirmed against a real Postgres earlier in this phase's work; everything else below has real integration tests written the same way (skipped unless a live database's connection details are supplied via env var, same pattern throughout this package) but they have not actually been run against a live database in this environment -- see /docs/phase-4-runbook.md's verification-status section for exactly what "not yet run" means here and why. Don't read "has a test for this" as "this was confirmed to work."

• internal/session issues/validates signed (HS256/JWT) tokens for both human sessions and /alerting's RoleService credential.
• internal/authhandler serves POST /internal/authorize (the endpoint api/authz.HTTPAuthorizer calls) and GET /auth/features (the runtime-capability check /web's settings page reads).
• api's /query and /dashboards endpoints enforce RBAC via authz.RequireRole/RequireRoleOrService, nil-safe (no-op) when ENTERPRISE_AUTH_URL isn't configured -- matches Phase 0-3 behavior.
• /alerting's queryclient presents a RoleService Bearer token (API_SERVICE_TOKEN) when configured -- see /docs/phase-4-isolation-design.md's alerting↔api gap.
• sentryctl presents $SENTRYCTL_TOKEN as a Bearer credential on every request when set.
• internal/rbacstore: full CRUD over users/tenants/ tenant_memberships/data_sources (metadata/migrations/0017-0032).
• internal/tenantprovision: real CREATE DATABASE/CREATE USER/ GRANT against ClickHouse. Its tests assert a tenant A user cannot read tenant B's database by fully-qualified name, and that system.query_log/system.tables/SHOW DATABASES don't leak across tenants either (task 2's finding was that the latter is version-dependent) -- not yet run against a live ClickHouse in this environment, see the note above.
• internal/chrunner: the tenant-scoped SQLRunner -- a per-tenant connection registry that resolves which tenant's ClickHouse connection to use from the authenticated identity in request context, never a parameter. Same adversarial probe, now through the actual production code path (chrunner.Registry.RunSQL, not just tenantprovision's raw grants).
• internal/audit.QueryAPILogger: the real api/queryapi.AuditLogger implementation -- wired into enterprise-api, no longer nil.
• internal/loginhandler: GET /auth/oidc/login + GET /auth/oidc/callback -- the actual human login flow, previously entirely missing. Redirects to the configured IdP with CSRF-protection state in a short-lived cookie, exchanges the code, verifies the ID token via internal/oidc, upserts a users row, resolves tenant/role from tenant_memberships (refuses with a clear error on zero rows; more than one starts a real tenant-selection round trip -- GET /auth/memberships + POST /auth/select-tenant, backed by a short-lived session.Manager.IssuePendingLogin token -- rather than guessing; see "Tenant selection" below), and issues a session cookie. This one genuinely is verified, unlike the ClickHouse pieces above: loginhandler_test.go runs the full flow against a real fake IdP (coreos/go-oidc's own oidctest package, real RS256 signing and verification, no live database or Docker needed) and every test passes. Not yet tried against a real external IdP or a running enterprise-auth container.
• internal/searchclient: the Tantivy-side sibling of chrunner -- implements api/querylang/executor.SearchClient, resolving SearchRequest.tenant_id (new field, proto/sentry/search/v1/ search.proto) from the authenticated request identity, same fail-closed shape as chrunner.Registry.RunSQL. Paired with search/src/registry.rs's IndexRegistry (Rust, opens a per-tenant Tantivy index on demand). Both genuinely verified -- unlike the ClickHouse pieces, Tantivy is an embedded library, so the isolation probe (three tenants, shared search term, scoped search returns only that tenant's document) actually ran: search's cargo test/cargo clippy --all-targets -- -D warnings and this package's go test both pass clean, no Docker or live database needed for either. Client also carries a TenantChecker (backed by rbacstore.TenantIsActive) since search/src/registry.rs's IndexRegistry opens-or-creates an index for any syntactically-valid tenant_id -- a real gap found while closing /docs/phase-4-isolation-design.md's verification-plan item 4: a mid-provisioning tenant would otherwise get a silently-empty search result instead of a refusal. Verified the same Docker-free way.
• cmd/enterprise-api: a second binary (alongside api/cmd/api, unchanged) importing both api's handler packages and the tenant-aware implementations above -- see its own doc comment for why this shape exists (enterprise → api is the allowed import direction; api can never import enterprise/). -provision-tenant=<id> is the operator action that provisions ClickHouse and marks a tenant active, same "offline action, not a network endpoint" shape as enterprise-auth -mint-service-token.

OIDC and SAML login are both now fully wired: internal/loginhandler serves GET /auth/oidc/login+GET /auth/oidc/callback and GET /auth/saml/login+POST /auth/saml/acs, converging on the same upsert-user/resolve-tenant/issue-session path. Both are verified the same way -- a real fake IdP with genuine cryptographic signing and verification (coreos/go-oidc's oidctest for OIDC, crewjam/saml/samlidp for SAML), no Docker needed, every test in loginhandler_test.go/saml_test.go passing including the full login round trip and negative paths (bad state/InResponseTo, expired/missing credential, no/multiple tenant memberships). Writing the SAML test caught two real bugs in internal/saml.ParseResponse, both fixed: missing r.ParseForm() before reading the POSTed SAMLResponse field, and email-attribute matching that missed the standard LDAP "mail" OID (urn:oid:0.9.2342.19200300.100.1.3) that IdPs send by default absent an explicit AttributeConsumingService request for "email" -- exactly what samlidp's own default assertion builder does. Neither protocol has been tried against a real external IdP or a running enterprise-auth container -- see /docs/phase-4-runbook.md §3a/§3b.

dashboard_permissions is now wired end to end: rbacstore/ dashboard_permissions.go is the raw CRUD, rbacstore/ dashboards_adapter.go's DashboardPermissions implements api/dashboards.PermissionStore (the interface core defines and carries as a nil-by-default field, same shape as queryapi.AuditLogger), and enterprise-api's main.go wires it in. api/dashboards' handler now enforces the matrix's "(own/granted)" qualifier: an Editor may edit/delete a dashboard (or its panels) they created, or one where a grant raises their effective role to Editor; managing grants themselves is stricter still -- creator or Admin/Owner only, closing a self-escalation path where a granted-but-not-creator Editor could otherwise extend their own access. metadata/migrations/ 0033_restrict_dashboard_permissions_role.sql fixes a divergence between 0024's actual CHECK constraint (allowed role='admin', nullable granted_by) and the design doc's schema (viewer/editor only, granted_by required) found while wiring this up. Verified against a fake PermissionStore in api/dashboards/handler_test.go (the full own/granted/admin/creator matrix, including the granted-editor-cannot- manage-grants regression); real integration tests exist in rbacstore_test.go but haven't run against a live Postgres in this environment, same disclosed gap as the rest of this package's Postgres-backed pieces.

Tenant selection (multi-membership identities)

The backend protocol for choosing a tenant is built and tested; the frontend page that would actually call it is deliberately not (see "Deliberately deferred" below). When resolveIdentity finds more than one tenant_memberships row for a logged-in identity, finishLogin issues a session.Manager.IssuePendingLogin token (a distinct Go/JWT type from a real session -- see that type's doc comment for a real bug this design caught in its own tests: a shared JSON key would have let a full session token double as a pending login) as a sentry_pending_login cookie (Path=/auth) and redirects to SELECT_TENANT_REDIRECT_URL (defaults to {POST_LOGIN_REDIRECT_URL}/select-tenant) instead of completing the login. From there:

• GET /auth/memberships -- lists the pending identity's tenants (tenant_id, tenant_display_name, role) to choose between.
• POST /auth/select-tenant with {"tenant_id": "..."} -- re-derives the role for that specific tenant server-side (never trusts a client-supplied role, only checks the claimed tenant_id against the identity's actual memberships, refusing with 403 otherwise), issues the real session cookie, and responds with {"redirect_url": "..."} for the caller to navigate to -- JSON, not a redirect, since this is a POST/fetch call a frontend page should control the navigation for itself.

Verified with the same real-fake-IdP tests as the rest of this package (loginhandler_test.go/saml_test.go): the full login -> pending cookie -> GET /auth/memberships -> POST /auth/select-tenant -> real session round trip, plus negative paths (missing/expired/wrong-type pending cookie, a tenant_id outside the identity's actual memberships, a real session token rejected when presented as a pending login).

Deliberately deferred, not half-built -- named explicitly rather than silently left out:

• The actual tenant-picker page -- nothing in web/ calls the endpoints above yet. Building it is genuinely different, larger scope than the backend protocol: web has zero session/cookie-handling code today (confirmed by reading it end to end while designing this), so a real picker page means adding that from scratch, plus CORS wiring (enterprise-auth has no CORS middleware at all right now -- a cross-origin fetch with credentials from web's origin needs it), neither of which is verifiable in this environment without a live backend and a browser session to exercise.
• Ingest write-routing, for either storage engine -- identity is now real (see "Ingest tenant identity" below), but nothing consumes it yet: chrunner/searchclient prove read isolation given tenant- scoped data exists, and every record ingest produces is now tagged with a real tenant ID, but neither ingest/internal/consumer (the ClickHouse writer) nor search/src/consumer.rs (a completely independent Redpanda consumer) reads that tag back to route the write anywhere per-tenant. Every record still lands in the single shared ClickHouse database and the single shared Tantivy index regardless of tenant. A newly-provisioned tenant's storage is real and isolated, and permanently empty. Now scoped, disclosed remaining work, not an undesigned gap -- see /docs/security/threat-model.md.

Deployment-topology routing (does traffic actually reach enterprise-api instead of api) is no longer deferred -- both deploy/helm/sentry and docker-compose.yml make it a single-flag choice now (enterprise. enabled / COMPOSE_PROFILES), see CLAUDE.md.

Ingest tenant identity

ingest (AGPL core) gained an optional TenantResolver (ingest/internal/grpcserver) -- nil by default, the same "off unless configured" shape as every other optional integration point in this codebase. When ENTERPRISE_AUTH_URL is set, PushBatch requires an authorization: Bearer <token> gRPC metadata entry on every call, resolves it via a new POST /internal/authorize-ingest endpoint on this service (internal/authhandler, backed by a new ingest_credentials table in internal/rbacstore -- only a SHA-256 hash of the token is ever stored), and attaches the resolved tenant ID to every record as a tenant_id Kafka message header before producing it. Fail-closed: once a resolver is configured, a missing or invalid credential refuses the whole batch, never falls back to "no tenant."

Mint a credential with -create-ingest-credential-tenant=<id> (prints the plaintext token exactly once -- see ingest_credentials' migration comment for why it can't be recovered again, only reissued); -list-ingest-credentials-tenant=<id>/-revoke-ingest-credential=<id> manage existing ones. ingest's own HTTP client (ingest/internal/tenantresolver.HTTPResolver) is the piece that actually calls /internal/authorize-ingest -- never an enterprise/ import (ingest is AGPL core), same "network boundary, not import boundary" shape api/authz.HTTPAuthorizer already uses for the query path.

What this does not do: change where a record is actually written. See "Deliberately deferred" above -- attaching a verified tenant identity as early as possible (right where the credential is presented) was built as a self-contained first step; per-tenant write-routing for both storage engines is separate, scoped follow-up work.

Future additions: per-tenant write-routing for ingest (ClickHouse and Tantivy both) -- see "Ingest tenant identity" above.

Why OIDC and SAML aren't hand-rolled

coreos/go-oidc (built on golang.org/x/oauth2) and crewjam/saml handle token/assertion signature verification, XML signing, and the protocol-level trust establishment — exactly the parts of an SSO integration where a from-scratch implementation is the highest-risk code in the whole feature. Both are well-established libraries, matching this project's existing "boring, well-understood dependency" pattern (clickhouse-go/v2, jackc/pgx/v5).

Building & testing

go build ./...
go vet ./...
go test ./...

internal/audit's real guarantees (the audit_writer grant restriction, the immutability trigger, hash-chain correctness under concurrency) can only be proven against a real Postgres — those integration tests are skipped by default and only run with AUDIT_TEST_POSTGRES_ADDR set:

docker run --rm --network sentry_default -v $(pwd)/..:/src -w /src/enterprise \
  -e AUDIT_TEST_POSTGRES_ADDR=metadata-postgres:5432 \
  -e AUDIT_TEST_POSTGRES_PASSWORD=audit-writer-dev-only \
  -e AUDIT_TEST_ADMIN_PASSWORD=sentry-dev-only \
  golang:1.25-alpine go test ./internal/audit/... -v

internal/rbacstore's tests are the same shape (real SQL, real constraints), skipped unless RBACSTORE_TEST_POSTGRES_ADDR is set:

docker run --rm --network sentry_default -v $(pwd)/..:/src -w /src/enterprise \
  -e RBACSTORE_TEST_POSTGRES_ADDR=metadata-postgres:5432 \
  -e RBACSTORE_TEST_POSTGRES_PASSWORD=sentry-dev-only \
  golang:1.25-alpine go test ./internal/rbacstore/... -v

internal/tenantprovision and internal/chrunner need a real ClickHouse instead (they mount the repo root, not just enterprise/, since internal/chrunner imports api/authz/api/querylang/executor via go.mod's replace directives to ../api):

docker run --rm --network sentry_default -v $(pwd)/..:/src -w /src/enterprise \
  -e TENANTPROVISION_TEST_CLICKHOUSE_ADDR=clickhouse:9000 \
  -e TENANTPROVISION_TEST_CLICKHOUSE_PASSWORD=sentry-dev-only \
  golang:1.25-alpine go test ./internal/tenantprovision/... -v

docker run --rm --network sentry_default -v $(pwd)/..:/src -w /src/enterprise \
  -e CHRUNNER_TEST_CLICKHOUSE_ADDR=clickhouse:9000 \
  -e CHRUNNER_TEST_CLICKHOUSE_PASSWORD=sentry-dev-only \
  golang:1.25-alpine go test ./internal/chrunner/... -v

Turning on auth enforcement for manual testing

Off by default (see "Status" above). To exercise the RoleService path end to end:

docker compose up -d enterprise-auth
TOKEN=$(docker compose run --rm enterprise-auth -mint-service-token=alerting)
# api: set ENTERPRISE_AUTH_URL=http://enterprise-auth:8082 and restart
# alerting: set API_SERVICE_TOKEN=$TOKEN and restart

docker build -f Dockerfile -t sentry-enterprise-auth .   # context is enterprise/, not the repo root

Bootstrapping a tenant and its first human user

-create-tenant/-grant-membership-* are enterprise-auth operator flags, same "offline action gated by access to enterprise-auth's own environment, not a network-reachable endpoint" shape as -mint-service-token -- deliberately not an authenticated HTTP admin API, which would have to solve "who's allowed to create the very first tenant/membership" itself. Replaces what used to be a manual psql dance (see /docs/phase-4-runbook.md §3a's history if you're wondering why old references to it still show up in git blame):

docker compose run --rm enterprise-auth -create-tenant=acme -display-name="Acme Corp"
# Log in once via /auth/oidc/login or /auth/saml/login -- it fails with
# "no tenant membership" (403), but UpsertUserBySSO already created the
# users row by then, which -grant-membership-user-email needs.
docker compose run --rm enterprise-auth \
  -grant-membership-tenant=acme -grant-membership-user-email=[email protected] -grant-membership-role=owner

# See who's actually in a tenant, and take access away again:
docker compose run --rm enterprise-auth -list-memberships-tenant=acme
docker compose run --rm enterprise-auth \
  -revoke-membership-tenant=acme -revoke-membership-user-email=[email protected]

-create-tenant only touches rbacstore -- pair with enterprise-api -provision-tenant (below) for a tenant to actually be able to run queries, not just log in. role=owner also calls SetOwner, since a tenant's Owner is a dedicated tenants.owner_user_id column, not just the highest tenant_memberships role -- -revoke-membership-* refuses to revoke a tenant's current Owner for the same reason (transferring ownership first has no flag yet, only rbacstore.SetOwner at the storage layer). Changing a role is just re-running -grant-membership-* with a different -grant-membership-role (SetMembership's upsert already supports it). Not yet built: a flag for dashboard_permissions grants (those go through the HTTP endpoints api/dashboards' handler now exposes -- PUT/DELETE /dashboards/{id}/permissions/{userId}, GET .../permissions).

Provisioning a tenant and running enterprise-api

api/enterprise-api are mutually exclusive in docker-compose.yml, gated behind COMPOSE_PROFILES (.env checks in single-tenant, i.e. plain api, as the zero-config default -- mirrors Helm's enterprise.enabled flag). -provision-tenant itself doesn't bind a port, so it runs fine regardless of the active profile; actually serving traffic on enterprise-api needs the enterprise profile active, since it now binds the same host port (8080) plain api does (it gets a default.aliases: [api] network alias too, so alerting's API_QUERY_URL/web's VITE_API_BASE_URL need zero changes either way):

COMPOSE_PROFILES=enterprise docker compose build enterprise-api   # context is the repo root, not enterprise/ -- see cmd/enterprise-api/Dockerfile
COMPOSE_PROFILES=enterprise docker compose run --rm enterprise-api -provision-tenant=acme -display-name="Acme Corp"
COMPOSE_PROFILES=enterprise docker compose up -d enterprise-api
curl -s http://localhost:8080/healthz

docker-compose.yml has no Kubernetes cluster to sync into, so TENANT_CRD_NAMESPACE is never set here -- -provision-tenant's internal/tenantcrd sync step is a documented no-op in this deployment shape, same as everywhere else this codebase has an "off unless configured" optional dependency. It only does anything in a real cluster with deploy/helm/sentry's tenantOperator.enabled=true -- see /deploy/helm/sentry/README.md's "Trying the two-tenant example."

-provision-tenant creates the tenant/data_source rows in rbacstore if they don't exist, provisions ClickHouse, persists the credentials, and marks the tenant active -- refuses to run twice for the same tenant (re-provisioning would either rotate a live credential or silently fail to, see tenantprovision.ProvisionClickHouse's doc comment).
