  ## 问题
</div>

尝试通过连接器从 PowerBI 连接到 ClickHouse 时，会收到身份验证错误。

此错误通常如下所示：

```
We encountered an error while trying to connect.
Details: "ODBC: ERROR [HY000] HTTP status code: 403
Received error:
Code: 516. DB::Exception: default: Authentication failed: password is incorrect, or there is no user with such name.
If you have installed ClickHouse and forgot password you can reset it in the configuration file.
The password for default user is typically located at /etc/clickhouse-server/users.d/default-password.xml and deleting this file will reset the password.
See also /etc/clickhouse-server/users.ml on the server where
ClickHouse is installed.
```

  ## 答案
</div>

请将 ClickHouse ODBC Driver 更新到 [1.4.1](https://github.com/ClickHouse/clickhouse-odbc/releases/tag/1.4.1.20250523) 版本。

如果无法更新，请检查密码中是否包含波浪号 (\~) ，因为在 [1.4.1](https://github.com/ClickHouse/clickhouse-odbc/releases/tag/1.4.1.20250523) 之前的版本中，这可能会导致问题。

我们建议为该连接使用专用用户，并手动设置密码。如果你使用的是 ClickHouse Cloud，并且需要与 `default` 用户等效的管理员级访问权限，请创建一个新用户并为其分配 `default_role`。
