Using Custom Authentication Logic

[BraianPita]

I have users, password hashes, and salts stored on a postgres DB, and I want to start using authentik to add OAuth/OIDC, Groups, roles, etc. However, I want to connect to my current database to do so and reuse my current users and passwords to avoid having to reset their passwords. Is there a way to do this?

I was thinking either being able to set the secret and method used to verify password hashes, or being able to setup a custom auth script so I can use my user's to authenticate. I don't have OAuth or any other procotol on this system so I can't use an external source.

The only feasible solution I see is to add any of authentik's supported federated- and social sources to your current setup (i.e. by developing a connector of sorts).
