 - **Auth, two transports**: API uses `Authorization: Bearer`; the HTMX UI uses an
   httpOnly cookie (`settings.cookie_name`). `app/deps.py` reads both. Web auth
   failures raise `NotAuthenticated`, handled in `main.py` as a redirect to `/login`.
-- **Credential verification** goes through `services/auth.authenticate(db, username,

-  `LDAP_DEFAULT_ROLES`), then falls back to local DB auth. LDAP config lives in
-  `settings.ldap_*`. Tests fake the blocking bind by patching `services.ldap._authenticate_sync`.

 Refresh tokens are stored server-side as a SHA-256 hash + `jti` with a `revoked`
 flag, so logout and rotation genuinely invalidate them.
 
-### LDAP / Active Directory (optional)
-
-Set `LDAP_ENABLED=true` to validate logins against a directory. On a successful
-bind, a local user is **provisioned on first login** (with an unusable local
-password and the roles in `LDAP_DEFAULT_ROLES`) so RBAC, tokens, and the admin
-UI work unchanged. Existing accounts still authenticate against the local
-database as a fallback, so the seeded superuser keeps working.
-
-Two lookup modes (configured in `.env`, see `.env.example`):
-
-- **Direct bind** — set `LDAP_BIND_DN_TEMPLATE`, e.g.
-  `uid={username},ou=people,dc=example,dc=com`; the login name is substituted
-  and used to bind directly.
-- **Search + bind** — leave the template empty and set `LDAP_BIND_DN` /
-  `LDAP_BIND_PASSWORD` (a service account) plus `LDAP_USER_SEARCH_BASE` /
-  `LDAP_USER_SEARCH_FILTER`; the user is located, then re-bound to verify the
-  password.
-
-The local user's email/name come from the `LDAP_ATTR_EMAIL` / `LDAP_ATTR_FULL_NAME`
-attributes. Use `ldaps://` (`LDAP_USE_SSL=true`) or `LDAP_START_TLS=true` in
-production so credentials aren't sent in cleartext.
-
 ## RBAC
 
 `users → roles → permissions`. Permissions follow `resource:action`
