Now you should be able to manipulate that user and create more users in the same pattern. Please understand that direct DB manipulation like this isn't strictly supported, but it should work as long as you're careful. Be sure to make frequent database backups and test often.

I would also suggest to NOT use local DB at all if you have a large user database and using an external auth server instead. Setting up an open source LADP server such as OpenLDAP has never been easier now that we have industry standard automation such as Docker Compose:
