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 exactly one tenant_memberships row (refuses with a clear error on zero or multiple -- no tenant-picker UI yet), 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.

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

• A tenant-picker UI/flow for an identity with more than one tenant_memberships row -- loginhandler refuses these logins outright rather than guessing (ErrMultipleMemberships).
• Ingest tenant-awareness, for either storage engine -- chrunner/ searchclient prove read isolation given tenant-scoped data exists, but nothing writes it: every record ingest produces still lands in the single shared ClickHouse database and the single shared Tantivy index. A newly-provisioned tenant's storage is real and isolated, and permanently empty. Undesigned, not just unbuilt -- see /docs/security/threat-model.md.
• Any deployment-topology mechanism that actually routes traffic to enterprise-api instead of api -- both binaries exist, docker-compose.yml includes enterprise-api available but not wired into web's default base URL, and the Helm chart has no service for it at all yet. This is now the single largest gap -- both storage engines' isolation mechanisms themselves are built.

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

-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. Not yet built: revoking a membership, listing a tenant's members, or 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

-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).
