 (asserts the blank-password validation still fires with the updated message). Manual: with user-secrets set on the dev box, `dotnet run --project src/ZB.MOM.WW.MxGateway.Server/...` and a dashboard `/login` as `multi-role` succeeds against the rotated GLAuth; the deployed-host login re-check from step 1 counts as the production verification. Live-LDAP integration tests (`MXGATEWAY_RUN_LIVE_LDAP_TESTS=1`) only where the GLAuth instance is reachable; otherwise document skipped per the testing matrix.
 
 **Outcome (2026-08-07 — Done, repo-side; live rotation operator-pending).** Landed on `fix/sec-36-ldap-secret`. **The design's baseline had already shifted:** at HEAD `appsettings.json` no longer commits the literal — it ships `"ServiceAccountPassword": "${secret:ldap/mxgateway/bind}"`, a fail-closed encrypted-store reference (documented `GatewayConfiguration.md:252`, tested by `PreHostSecretExpansionTests`) introduced by the Secrets-store adoption after this remediation was written. **Deviation from Implementation step 2:** the `${secret:}` reference was **kept, not deleted** — deleting it regresses the shipped/documented/tested store channel and the committed-plaintext finding is already resolved for `appsettings.json`. The load-bearing residual — the literal value still present in `glauth.md`'s samples (`:33,65,103,136,245`), `docs/GatewayTesting.md`, and the historical `archreview/*` SEC-06 evidence — was scrubbed to `<service-account-password>` placeholders, each with a pointer to the source of truth `scadaproj/infra/glauth/` and a rotation-required note. Steps 3–6 implemented as designed: `<UserSecretsId>mxaccessgw-server</UserSecretsId>` added (step 3); the `ValidateLdap` blank-password message now names both channels — dev `dotnet user-secrets set "MxGateway:Ldap:ServiceAccountPassword" <value>` and deployed `MxGateway__Ldap__ServiceAccountPassword` — plus a note on the `${secret:}` store default (step 4), asserted by the extended `Validate_Fails_WhenLdapEnabledAndServiceAccountPasswordBlank`; docs updated same commit (step 5); `git grep -i` for the old value is empty across tracked files (step 6). The cross-repo **step 1 (rotate GLAuth on `10.100.0.35`, pre-stage the NSSM env var on `10.100.0.48` and on `wonder-app-vd03` only if `Ldap.Enabled`, verify dashboard login)** is the operator's to execute, captured in the new runbook `docs/runbooks/SEC-36-ldap-credential-rotation.md`. Verification (macOS): `dotnet build …Server` 0 warnings/0 errors; `dotnet test --filter ~GatewayOptionsValidator` green.

+**Outcome (2026-08-07 — operator half executed; finding now fully `Done`).** The cross-repo step 1 left open above was executed per `docs/runbooks/SEC-36-ldap-credential-rotation.md`. A new service-account password was generated, the `serviceaccount` `passsha256` in `scadaproj/infra/glauth/config.toml` replaced, and the shared GLAuth recreated on `10.100.0.35` from its actual compose directory — the **load-bearing** half of the finding is now discharged: the value disclosed by this repo's git history (live in the directory since 2026-06-04; not reproduced here) no longer binds `dc=zb,dc=local`. The new value exists only in the three channels the design named — the GLAuth `passsha256` (committed in `scadaproj`, commit `aada53b`), the NSSM service environment on `10.100.0.48`, and each dev box's user-secrets — and in no file of this repo. The retired plaintext was additionally scrubbed from the `scadaproj` glauth comments (`config.toml`, `docker-compose.yml`, `README.md`) and from the docker host's live `docker-compose.yml`; the host's `*.bak-sec36` rollback copies deliberately retain it. **Three runbook facts were wrong and are corrected in a dated block at its top.** (1) Its step 3 said `cd ~/Desktop/scadaproj/infra/glauth` on the docker host; no such path exists there — the stack runs from `/home/dohertj2/zb-glauth` (container `zb-shared-glauth`), fed by the `scp` deploy documented in `scadaproj/infra/glauth/README.md`. (2) `wonder-app-vd03` is **out of scope on documentary evidence**, not merely unchecked: its gateway binds the ScadaBridge/ScadaLink local GLAuth under `dc=scadalink`/`dc=scadabridge`, a different directory that never held this credential (the host is also unreachable from the dev network); no env var was staged there. (3) Its "3-fail / 10-minute per-IP lockout" caution is **inert for this instance** — `config.toml:14` sets `LimitFailedBinds = false`. **One Done criterion is met with a caveat:** the new value **is** staged on windev (`10.100.0.48`, 10th `AppEnvironmentExtra` entry on the `MxAccessGw` NSSM service), but the runbook's primary check — dashboard `/login` as `multi-role` — **could not run**, because windev's gateway is crash-looping on an unrelated pre-existing fault: the deployed Server binary (2026-06-25) predates the 2026-07-15 auth-DB migration, so it opens a schema-version-3 database it supports only at version 2 and aborts at startup (~10k Hosting-failed events/day since at least 08-06). That is a stale-deployment problem, filed as a next-cycle candidate finding, not a rotation defect. **Verified instead by the equivalent primitive:** a direct `ldapsearch` bind as `cn=serviceaccount,dc=zb,dc=local` with the new value against `10.100.0.35:3893` succeeded and returned the `multi-role` entry — the same search bind the dashboard performs. Also surfaced and filed for next cycle: `DashboardLdapLiveTests` fixture drift leaves the suite with **no positive-proof coverage** of the service-account bind, so it could not have substituted for the dashboard check either. Tracking: both registers' SEC-36 rows, the pending-operator-actions list in `90-candidate-findings-next-cycle.md`, and the `00-tracking.md` progress log.
