Symptoms
In MySQL 8.0.27, the authentication_policy option was added, and the following warning is output to the error log at startup if you are setting the default_authentication_plugin in my.cnf.
To avoid this warning, you need to set only authentication_policy, but if you want to use the 'mysql_native_password' authentication method, you may have connection problems.
