Description of Changes

What

Adds SCIM 2.0 user provisioning (RFC 7643/7644), so identity providers like Okta and Microsoft Entra ID can create, update, deactivate and remove Stirling users automatically. This is an Enterprise feature (@EnterpriseEndpoint). Our plan and agreement copy already lists SCIM, but it was never built.

It adds no new dependencies or database migrations. SCIM is off until a token is configured.

How it works

  • Endpoint: /api/v1/scim/v2/Users, supporting GET (list, plus filter=userName eq "..."), GET /{id}, POST, PUT, PATCH and DELETE. Errors use the SCIM error schema, and application/scim+json is accepted.
  • Auth: a static bearer token from security.scimToken (env SECURITY_SCIMTOKEN). This is the standard SCIM model: Entra's "Secret Token" and Okta's "HTTP Header" auth. ScimTokenFilter checks it for /api/v1/scim/** only, using a constant-time comparison. Normal API keys and JWTs cannot reach these endpoints, and the token cannot reach anything else.
  • Users: provisioned users have no password and take the configured SSO auth type (SAML2 or OAuth2), so they sign in through SSO. SCIM userName maps to the Stirling username, which is what SSO login matches on.
  • PATCH: handles both the Okta style (no path, attribute map in value) and the Entra style (path: "active", "Replace", string "False").

Security hardening

  • Admins are off-limits: SCIM can list admins but gets a 403 if it tries to rename, disable, replace or delete one. Without this, a leaked token could rename an admin to an address the attacker controls through SSO.
  • DELETE deactivates by default. A new toggle, security.scimDeleteRemovesUser: true, makes it permanently erase the user and their files instead.
  • The token must be at least 32 characters. A shorter token keeps SCIM off and logs a warning at startup.
  • Audit: requests are attributed to scim-provisioning, and every create, rename, activation change and delete is logged with the username.
  • The internal API user is hidden and can't be touched. The user licence limit still applies; going over it returns a SCIM 403.

Scope

Users only. SCIM Groups (mapping to teams) is not included.

Setup (for docs)

  1. Generate a token (openssl rand -hex 32) and set SECURITY_SCIMTOKEN.
  2. Entra ID: Enterprise app > Provisioning > Automatic. Tenant URL is https://<host>/api/v1/scim/v2, plus the Secret Token.
  3. Okta: enable SCIM provisioning. The base URL is the same, the unique identifier is userName, and auth is HTTP Header.
  4. Map userName to the same value SSO uses as the Stirling username (usually email).

Tests

  • Unit: ScimTokenFilterTest (valid, wrong, missing and short tokens; other paths untouched) and ScimUserControllerTest (create, 409 on duplicate, filter hit/miss/unsupported, internal user hidden, Okta and Entra PATCH, a rename that doesn't re-enable a user, delete toggle, admin protection, Enterprise annotation).
  • Live against a locally built jar:
    • Auth: bad, missing or X-API-KEY credentials get 401, and admin login still works.
    • Users: create, duplicate, filter, get, both PATCH styles, rename, PUT, list, and delete as deactivation all behave as expected.
    • Licence: without a licence the endpoint returns 403; with the test licence it returns 200.
    • Hardening: changing an admin gets 403, and a short token keeps SCIM off with the warning logged.
  • task fix is clean. task check passes except for tests that already fail on Windows and that this PR doesn't touch (CalibreSandboxPolicyTest, PipelineDirectoryProcessorOutputPathTest, NativeLicenseLoaderTest).

Checklist

General

Testing (if applicable)

  • I have run task check to verify linters, typechecks, and tests pass
  • I have tested my changes locally. Refer to the Testing Guide for more details.

Summary by CodeRabbit

  • New Features
    • Added SCIM 2.0 user provisioning, including user listing, lookup, creation, and updates.
    • Added bearer-token authentication for SCIM requests.
    • SCIM user listings support username filtering and pagination; internal API accounts are excluded.

Walkthrough

This change adds configurable SCIM bearer-token authentication and user provisioning endpoints. The endpoints support listing, retrieving, creating, replacing, patching, and deleting users. A setting controls whether DELETE deactivates users or removes users and their files. Dynamic YAML debug logging now reports property names or the source name.

Changes: SCIM provisioning

Layer / File(s) Summary
SCIM settings and authentication
app/common/.../ApplicationProperties.java, app/core/.../settings.yml.template, app/proprietary/.../SecurityConfiguration.java, app/proprietary/.../ScimTokenFilter.java, app/proprietary/.../ScimTokenFilterTest.java
Adds the SCIM token and deletion-policy settings. The security chain applies token authentication to SCIM paths. Filter tests cover accepted, rejected, and out-of-scope requests.
SCIM user lookup and creation
app/proprietary/.../ScimUserController.java, app/proprietary/.../ScimUserControllerTest.java
Adds user listing with filtering and pagination, ID-based retrieval, and user creation. Responses include SCIM resource fields. Tests cover creation, lookup, filtering, and internal-user exclusion.
SCIM user updates and deletion
app/proprietary/.../ScimUserController.java, app/proprietary/.../ScimUserControllerTest.java
Adds replacement, PATCH, and DELETE operations. Updates check usernames and active state. Access checks protect admin and internal users. DELETE removes or deactivates users according to configuration. Error responses use the SCIM error format.

Property-source logging

Layer / File(s) Summary
Dynamic YAML debug output

Dynamic YAML debug logging reports property names for enumerable sources, or the source name otherwise.

Explanation

The title names the main change: adding SCIM 2.0 user provisioning as an Enterprise feature. The changeset adds the SCIM endpoints, the bearer-token filter, and the related settings and tests, so the title matches the primary change.

Full details: Description check

Explanation

The description follows the template's structure. It has a 'Description of Changes' section that covers what changed, how it works, security hardening, scope, setup steps, and tests. The checklist is present and mostly ticked. Two gaps remain: the 'Closes #(issue_number)' line is missing, and the Documentation and Translations checklist items were removed without being addressed. The UI Changes item was also dropped, which is reasonable since the change has no UI. The content is thorough and specific.

Resolution

Consider adding a 'Closes #(issue_number)' line if an issue exists. Also confirm whether the Documentation checklist item applies, since the setup steps are described 'for docs' and the docs repo may need updating.

user, keeping the 201 status and response body intact.

- Line 107: Update ScimUserController to treat supported SCIM attribute names
case-insensitively in both the create flow that reads body.get("active") and the
apply method that handles PATCH paths. Normalize attribute names before lookup
or dispatch so inputs such as "Active" correctly set the account state; preserve
existing behavior for other attributes.
- Line 123: Update ScimUserController.patch so the complete SCIM operation
sequence, including username-conflict checks and service updates, runs within
one rollback boundary. Ensure UserService updates participate in that shared
transaction rather than committing independently, so any failed operation rolls
back earlier changes.

Reject PATCH operations that this handler does not implement.

The loop never reads op. For example, {"op":"remove","path":"userName"} returns success without removing the attribute or reporting that this required attribute cannot be removed. Validate op and path, then either implement the operation or return a SCIM error. (rfc-editor.org)

Major · Security & Privacy · Quick win

Exclude scimToken from generated string output.

Security uses Lombok @Data, so its generated toString() includes scimToken. KeygenLicenseVerifier logs applicationProperties.toString() at debug level on successful license validation. When debug logging is enabled, the SCIM bearer token is written to the log. Other secret fields in this file use @ToString.Exclude.
