## Versioning
All five packages are versioned **lockstep** from `Directory.Build.props`. The current release is **0.3.0**. A single version bump in `Directory.Build.props` bumps all five packages simultaneously — consumers should reference the same version for all ZB.MOM.WW.Auth packages.

### 0.4.0 — LDAP sign-in by user bind (opt-in)
- **`LdapOptions.BindMode`** (`ServiceAccount` default | `User`), **`UserBindTemplate`** (`{0}` = the login name, e.g. `{0}@example.com` or `EXAMPLE\{0}`) and **`AcceptDomainQualifiedNames`** (default `true`).
- In `User` mode `LdapAuthService` binds as the user; success authenticates them and the same connection reads their entry (`UserNameAttribute`, `DisplayNameAttribute`, `GroupAttribute`). No `ServiceAccountDn` / `ServiceAccountPassword` is needed or validated.
- Failure mapping: empty password or an unusable name → `BadCredentials` with no network call (AD treats an empty-password simple bind as an unauthenticated success). Bind result 49 → `BadCredentials`, final — never retried on a fallback DC, so one wrong password is one lockout strike. Any other bind error, a connect failure or a search failure → the system-side bucket (`ServiceAccountBindFailed`) and the next endpoint. Zero/several entries or no groups after a good bind → `GroupLookupFailed`.
- `DOMAIN\name` / `name@suffix` are reduced to `name` (or refused when `AcceptDomainQualifiedNames` is `false`), so the result's `Username` has one spelling.
- No `Abstractions` contract change beyond the new enum and option properties; `ServiceAccount` mode is unchanged.
- `UserBindTemplate` output is used verbatim as the bind name, so use a UPN (`{0}@example.com`) or down-level (`EXAMPLE\{0}`) template; a DN template is not escaped.
### 0.3.0 — SQL Server API-key store (ScadaBridge central pair)
