Hello, is there a way to change core to override the data source provider for email pwd ? I want to integrate supertoken with ldap.
It's okay if we lost fuctionallity like  reset pwd, change user data etc. 
Our use case is use supertoken as auth session management, no signup flow, reset password, etc.

you can use supertokens for session management only as well.

See our sessions guide: https://supertokens.com/docs/session/introduction

Essentially, post login (however you login), you call the `Session.createNewSession` function with the user ID of the user. This will work even if supertokens doesn't already know about that user ID from before

As shown here: https://supertokens.com/docs/session/common-customizations/sessions/new-session

Great, this was my first thoughts. thank you
