Wave 10 — Okta OIDC authentication

Fresh wave 10. The label was previously used by the LDAPS work under D13/D14, built on feat/ldaps-directory-auth; that branch was deleted rather than merged and never appeared in IMPLEMENTATION.md's wave table, so it carries no claim on the number. See docs/waves/decisions-2026-09-02.md (D15) for why LDAPS was retired before deployment and Okta chosen instead.

Depends only on main as it stands after D15. Not sequenced behind any other wave.

Tasks

• T10.1 — Add the Okta OIDC client. Authlib as a dependency. Config via env vars (OKTA_ISSUER, OKTA_CLIENT_ID, OKTA_CLIENT_SECRET, OKTA_REDIRECT_URI), same pattern AUTH_SECRET_KEY already uses in server/auth.py.

• T10.2 — Login-redirect and callback routes. A route that sends the browser to Okta's authorize endpoint, and a callback route that exchanges the code for tokens and validates the ID token. Access gating is Okta's job, not this app's: only accounts assigned to the app integration in Okta can reach it at all, so there is no app-side required-group or claim check layered on top. This is a deliberate difference from D13, which had to gate on a required AD group itself because an LDAPS bind alone could not distinguish an assigned user from any other domain account.

• T10.3 — Identity matching and JIT provisioning. Reuses D13's shape (_provision_from_directory-style matching) keyed off an OIDC claim instead of an LDAP search result. Open dependency: which claim carries the AD sAMAccountName equivalent (preferred_username, upn, or a custom claim) is asked of security and not yet answered. Build with a configurable claim name and a documented default, not a hardcoded one, so the answer can drop in without a code change.

• T10.4 — Remove the local password path entirely. Drop password_hash (Alembic migration; plain op.drop_column, matching existing precedent for other NOT NULL columns on users — no batch_alter_table needed), remove the bcrypt-based login(), remove the username/password form. Real deletion, matching D15's "full replacement," not a toggle or a fallback. Scope corrected by D16 after hazard review turned up more call sites than the original bullet named:

  • create_user() and admin_reset_password() in server/app.py (admin console's "add user" and "reset password" routes) — rework to drop the password field entirely rather than break.
  • html/users.js's "add user" form (nu-password) and "Reset password" button — matching frontend change.
  • server/manage_users.py — reworked per D16 from account creation to promotion: create-admin/create/reset-password (password-based) are replaced by a promote-by-username command that operates on a row Okta's JIT provisioning (T10.3) already created, never a hand-typed new one. This is now the documented admin-bootstrap path — see D16.
  • tests/browser_check.py and tests/launcher_check.py — stop calling auth.hash_password() to seed fixture rows.
  • server/smoketest.py and server/seed_demo.py — currently authenticate via POST /api/auth/login. Switch to minting a session with auth.create_token() directly, the same technique browser_check.py already uses, so both scripts (named explicitly in CLAUDE.md's verification section) keep working without depending on T10.7's timing.

• T10.5 — Frontend: login becomes a redirect, not a form. login.html/login.js change to a "Sign in with Okta" flow. Sign-out lands back on the app's own login page.

• T10.6 — Deployment docs and env var reference. DEPLOYMENT.md, server/.env.example, server/README.md describe the Okta config in place of the LDAP config they never ended up describing (D13 never shipped, so these still describe the original local-password system today).

• T10.7 — Test coverage without a live Okta dependency. A fake-OIDC-provider test seam, mirroring ldap_fake.py, so the suite runs with no live Okta tenant reachable. Built: server/okta_fake.py (env-driven, WP_OKTA_FAKE_DIRECTORY, production-refusing the same way ldap_fake.py does), dispatched from okta_auth._build_oauth() before the real Authlib client is considered. Only the two Authlib calls that touch the network — authorize_redirect / authorize_access_token — are faked; app.py's okta_login()/okta_callback() (the ?next= guard, the disabled-account check, JIT provisioning, the identity-claim lookup) run unmodified against the fake, same boundary the LDAP predecessor drew around the anonymous-bind guard. Two fake-only routes (/_fake_provider, /_fake_provider/consent) stand in for Okta's own sign-in screen and are registered in app.py only when the fake is active at import time — in production they do not exist, not merely refuse. tests/browser_check.py's start_server() now takes an optional extra_env and sets WP_OKTA_FAKE_DIRECTORY unconditionally (same reasoning ldap_fake's equivalent used: almost nothing signs in, but the one check that does should not fail mysteriously). tests/url_state_check.py scenario 2 is un-skipped and drives the real round trip — login.html's button, the fake picker page, the fake consent redirect, okta_callback() — proving ?next= survives it, same tightened "actually left login.html" assertion the LDAP predecessor's own bug fix used. tests/okta_auth_check.py is new: the production guard, single-use/replay on the authorization code, an unsolicited callback hit, a tampered state, a denied consent, an unknown identity, a disabled account, JIT provisioning, an existing admin surviving unchanged, same-site vs. off-site ?next=, and OKTA_IDENTITY_CLAIM genuinely working under a non-default claim name — 22/22.

• T10.8 — Verification. 390px and 1440px, full suite, done-when checks per task, matching the rigor D13 was held to.

Still open

• The OIDC claim mapping (T10.3).
• Final confirmation of the redirect/callback URI (https://wp.controls.dev/api/auth/okta/callback proposed, pending security).
• The Business Technology Group pilot assignment in Okta.

Closed since first written: admin bootstrap and break-glass posture, previously open questions, decided in D16 (2026-09-03) and folded into T10.4 above.
