Summary

Three small OIDC robustness fixes that surfaced while integrating Huly with Authentik for a production WAC v1 deployment. All three are standalone and have no dependency on the forthcoming WAC v1 stack.

Commits

1. fix(authProviders): instrument OIDC callback + redirect on fail (not 500)

Problem: Every OIDC callback (bogus or real code) returned 500 Internal Server Error, even with valid sessions. No log line was emitted between try auth via openid and the 500 — passport-strategy errors threw silently before handleProviderAuth could log them.

Fix:

  • Switch to the explicit-callback passport.authenticate variant so strategy errors surface as err/info/status args instead of being swallowed.
  • Privacy-safe diagnostic shape: no raw code / state / tokens / user. Logged fields are stage, errMessage/Name/Stack, hasUser, infoSummary, statusCode, hasSession + sessionKeys (names only), cookie + state + code presence (lengths only), host, forwardedProto.
  • Permanent invalid-callback guard: ALL failures → 302 /login?error=oidc_callback_failed, never 500. Same wrap covers handleProviderAuth throws.

2. fix(account): admin.ts trim+lowercase on both env-set AND lookup

Problem: server/account/src/admin.ts built the ADMIN_EMAILS set without normalizing, AND isAdminEmail() didn't normalize the input. Today's value happens to be clean, but a future env value like ADMIN_EMAILS=" Michael@Uray.io " would silently break admin detection (Set lookup would miss the lowercased input).

The Mongo backend already has this hardening (server/account/src/collections/mongo.ts:1141-1147). Postgres + this helper didn't.

Fix: Both sides normalize. Env split → trim → toLowerCase. Entries without @ are kept for backwards compatibility with deployments that use login-id style ADMIN_EMAILS values (e.g. ADMIN_EMAILS=admin,...). A warn is emitted listing the kept-but-malformed entries. Tests cover whitespace, case-insensitive env, case-insensitive lookup, kept-with-warn for no-@ entries, empty/unset env, multi-entry.

3. chore(authProviders): drop cookieHeaderLen from OIDC diagnostics

Rationale: hasCookieHeader (boolean) is sufficient to diagnose missing session-cookie issues; the cookieHeaderLen byte count adds no operational value and is one more PII-adjacent surface. Removed from both diagnostic paths in pods/authProviders/src/openid.ts.

Out of scope

The OIDC name-split heuristic for IdPs that violate OIDC §5.1 (given_name = full_name) ships separately in #10919 — Authentik will fix this upstream in v2026.8 (PR #21544), so the Huly-side patch remains defense-in-depth.

…500)

Production-blocking: every OIDC callback (bogus or real code) returned
500 Internal Server Error, even with valid sessions. No log was emitted
between `try auth via openid` and the 500 — passport strategy threw
silently before `handleProviderAuth` could log.

Per Codex plan-review amendments:
- Switch to explicit-callback passport.authenticate variant so strategy
  errors surface as err/info/status args instead of being swallowed.
- Privacy-safe diagnostic shape (no raw code/state/tokens/user). Fields:
  stage, errMessage/Name/Stack, hasUser, infoSummary, statusCode,
  hasSession + sessionKeys (names only), cookie + state + code
  PRESENCE (lengths only), host, forwardedProto.
- Permanent invalid-callback guard: ALL failures → 302 to /login with
  ?error=oidc_callback_failed, never 500. Same wrap covers
  handleProviderAuth throws.

Next step (P0-T2): user attempts login, we capture the actual error
from the diagnostic, then ship a surgical fix in r8.

Codex plan-review Critical: server/account/src/admin.ts:15-18 built the
ADMIN_EMAILS set without normalizing, AND isAdminEmail() didn't normalize
the input. Today value is clean so isAdmin works, but a future env-value
like ADMIN_EMAILS=" Michael@Uray.io " would silently break admin
detection (Set lookup would miss the lowercased input).

Mongo backend already has this hardening (collections/mongo.ts:1141-1147).
Postgres + this helper didn't.

Now BOTH sides normalize: env split -> trim -> toLowerCase -> filter
non-empty + warn on no-@ entries (Codex Optional: warn not reject --
too sharp for a latent fix). Lookup also trim().toLowerCase().

Standalone upstream-PR-able per Codex Q-I3.

Tests cover whitespace, case-insensitive env, case-insensitive lookup,
invalid-shape warn, empty/unset env, multi-entry.

…amendment)

Codex E4 amendment (optional, low-priority): hasCookieHeader is
sufficient to diagnose missing session-cookie issues; the
cookieHeaderLen byte count adds no operational value and is one more
PII-adjacent surface to keep an eye on. Drop it from both diagnostic
paths in pods/authProviders/src/openid.ts.

Bei jedem fehlgeschlagenen OIDC-Callback wurde ein umfangreicher Diag-Block
(errStack/sessionKeys/host/…) auf error-Level geloggt -> anonymes Log-
Flooding via wiederholter invalider Callbacks. Normalbetrieb loggt jetzt nur
eine knappe Fehlerzeile; der volle Diag-Block nur mit OIDC_DEBUG=true.

… allowed (L-AUTH-3)

Ein Tippfehler wie ADMIN_EMAILS=admin,michel@... legte bislang einen
unbeabsichtigten Admin-Identifier an (Eintrag ohne @ wurde still behalten).
Jetzt werden @-lose Eintraege per Default verworfen (fail-closed) und nur
bei ADMIN_EMAILS_ALLOW_LOGIN_ID=true als Login-ID akzeptiert; Warnung stets.

…L-AUTH-4)

handleProviderAuth liefert '' bei einem nicht aufloesbaren Login (z.B. kein
Account + Signup disabled). Bisher erfolgte dann kein Redirect und next()
lief ins Leere -> haengende/leere Antwort. Jetzt fail-closed: explizites
302 auf /login?error=oidc_no_account.

The account service registered the OIDC passport strategy only once at
startup via a single fire-and-forget Issuer.discover(). A transient issuer
outage in that one boot moment left the 'oidc' strategy permanently
unregistered, producing 500 "Unknown authentication strategy" on every
OpenID login until a manual container restart (observed: ~10 days).

Make registration self-healing:

- Extract registerOidcStrategyWithRetry(), which retries the ENTIRE
  registration chain (discover -> new Client -> new Strategy -> passport.use)
  with capped exponential backoff (5s, x2, cap 60s), unbounded. The loop only
  returns after passport.use succeeds, so a failure at client or strategy
  construction (e.g. temporarily incomplete issuer metadata during an IdP
  upgrade) is retried too instead of permanently disabling OIDC. discover and
  sleep are injectable for tests; passport is a structural { use } interface.
  It never rejects: the success log runs failure-safe AFTER passport.use and
  returns immediately, so a throwing logger can never re-enter the loop and
  register the strategy a second time; the failure warn is likewise guarded so
  a throwing sink cannot break the never-rejects contract.

- Gate log flooding via shouldWarnOnAttempt(): warn on the first 5 attempts
  and every 60th thereafter (~24 warn lines/day at the 60s cap instead of
  ~1440), following the branch's L-AUTH-2 rationale; error stacks only under
  OIDC_DEBUG. Success logs once with the attempt count.

- Wire it fire-and-forget in registerOpenid() and flip an oidcReady flag on
  success. The .then body is a plain boolean flip that cannot throw; a trailing
  .catch(() => {}) is belt-and-suspenders so this fire-and-forget chain can
  never surface an unhandled rejection. Routes stay registered synchronously.

- During the pending window, /auth/openid responds 503 with Retry-After: 5
  and a short text body instead of a 500 or a redirect (the login app ignores
  an error query param, and L-AUTH-4 only covers the callback path).

Add the package's first tests: the retry helper in isolation (schedule, 60s
cap, whole-attempt retry incl. client-construction failure, warn gating,
OIDC_DEBUG both ways, a throwing success log that must not re-register, and a
throwing failure warn that must not reject) and the registerOpenid wiring
(synchronous route registration, 503 pending window, exactly-once strategy
registration).
