 - 只处理当前在职用户。
 - 只更新 AD 中已存在的 `sAMAccountName` 用户，不自动创建 AD 账号。
 - 更新前会比对 AD 当前值与 EHR 目标值；一致则跳过，不一致才更新差异字段。
+- 默认写入后立即回读校验；如果 LDAP 返回成功但字段未落地，Job 会报失败并记录未生效字段。
 - EHR 目标值为空时不会清空 AD 字段。
 - 如果配置了 `target_sam_accounts`，只对列表中的 AD 账号执行同步。

 - `target_sam_accounts`: 可选，字符串数组。传入后只同步这些 AD 账号；不传则同步所有当前用户。
 - `dry_run`: 可选，默认 `false`。建议首次配置为 `true`，只记录会变更的字段，不写入 AD。
+- `verify_after_write`: 可选，默认 `true`。真实写入后回读 AD 字段，确认修改已落地。
 - `ldap_uri`: AD LDAP 地址，如 `ldaps://dc01.vastai.com:636`。
 - `ldap_base_dn`: AD 用户搜索根 DN。
 - `ldap_user_filter`: 用户搜索过滤器，默认 `(sAMAccountName={sAMAccountName})`。
