我最近将数据税企业从4.8.16升级到5.0.15。我们使用PlainText格式的密码身份验证。但下面的消息不断出现在日志中。

如何摆脱这个消息，因为我现在不感兴趣使用加密？
您需要设置：
authentication_options:
plain_text_without_ssl: allow
在dse.yaml配置文件中。可能的设置有：
block - block the request with an authentication error
warn - log a warning about the request but allow it to continue (default)
allow - allow the request without any warning
