username passthrough to backend datasource

[mlocutus]

Hello,
we are working on a use case where many 100s of users each have their own username and password for database access. We would like to utilize ShardingSphere-proxy as a front end proxy for those users to access the database.

From what I've found in the documentation, it appears that datasource needs to be configured in the yaml file with a username and password ahead of time. For our use case, it would be preferable if we could just configure the database url in the config file and dynamically accept username/password at connection time.

Is there any way that sharding sphere can be configured such that the username / password a user provides as part of their connection to the database (e.g. via psql or some other database client) could be passed through directly to the back end database for authentication?
