Postfix: switching from users in MySQL to users in AD - how?

Question

linux

Hello. There is Postfix, stores users locally in MySQL. There is an AD with users whose logins are EXACTLY the same as in mysql. Accordingly, the task is to cut the authorization to the domain one. How to deal with mail so that after authorization with a domain account, the same mailbox opens as under a non-domain account? Those. now the user logs in as username, but will be as DOMAIN/username.
