| `MxGateway:Ldap:AllowInsecure` | `true` | Permits a plaintext bind. Must be `true` when `Transport` is `None`; set `false` (with `Ldaps`/`StartTls`) in production. |
| `MxGateway:Ldap:SearchBase` | `dc=zb,dc=local` | Search base DN. |
| `MxGateway:Ldap:ServiceAccountDn` | `cn=serviceaccount,dc=zb,dc=local` | Bind DN for the search account. |
| `MxGateway:Ldap:ServiceAccountPassword` | `${secret:ldap/mxgateway/bind}` | Search-account password. **Never a committed plaintext value (SEC-36):** the shared GLAuth bind credential is supplied out-of-band through one of three channels, all binding to this key. **(1) Encrypted secrets store (shipped default):** `appsettings.json` ships the reference `${secret:ldap/mxgateway/bind}`, which the pre-host `${secret:}` expander resolves at startup from the encrypted secrets store (the code-side design default is blank, so a missing/unresolved value fails closed rather than falling back to a leaked credential). Seed it once with `secret set ldap/mxgateway/bind <value>` (the store's master key must be present via `ZB_SECRETS_MASTER_KEY`); startup aborts with `SecretNotFoundException` if the secret is absent. **(2) Deployed hosts — env var:** override directly with `MxGateway__Ldap__ServiceAccountPassword` (double-underscore form) in the NSSM service environment — a plain literal there is used as-is and the store lookup is skipped. **(3) Dev boxes — user-secrets:** `dotnet user-secrets set "MxGateway:Ldap:ServiceAccountPassword" <value>` (the server carries `<UserSecretsId>mxaccessgw-server</UserSecretsId>`; user-secrets load automatically in the Development environment and live under the user profile, outside the tree). The value comes from the GLAuth source of truth `scadaproj/infra/glauth/`, never from a repo file. **Rotation:** because the credential was historically committed, rotating it in `scadaproj/infra/glauth/` (and redeploying the shared GLAuth on `10.100.0.35`) is required — see `docs/runbooks/SEC-36-ldap-credential-rotation.md` for the cutover order. A blank/unresolved value fails startup validation with a message naming the two supported channels. |
