I'm using Amazon Aurora Serverless MySQL cluster(MySQL 5.7) and want to change the value of global variable default_authentication_plugin which is currently set to default ie. mysql_native_password
These are the commands I'm using to update the default authentication plugin
SET GLOBAL default_authentication_plugin = 'sha256_password';
SET @@GLOBAL.default_authentication_plugin = 'sha256_password';
But I'm getting below error
From the documentation, I can see the default_authentication_plugin is not a dynamic variable.
Also, I have checked in the DB Cluster Parameter Group the default_authentication_plugin parameter is not available there as well.
How do I change the value of the default_authentication_plugin in this case? Can someone help me?
