LDAP to UNIX user proxy (lemmy.ml)

Is there any service that will speak LDAP but just respond with the local UNIX users?

Right now I have good management for local UNIX users but every service wants to do its own auth. This means that it is a pain of remembering different passwords, configuring passwords on setting up a new service and whatnot.

I noticed that a lot of services support LDAP auth, but I don't want to make my UNIX user accounts depend on LDAP for simplicity. So I was wondering if there was some sort of shim that will talk the LDAP protocol but just do authentication against the regular user database (PAM).

The closest I have seen is the services.openldap.declarativeContents NixOS option which I can probably use by transforming my regular UNIX settings into an LDAP config at build time, but I was wondering if there was anything simpler.

(Related note: I really wish that services would let you specify the user via HTTP header, then I could just manage auth at the reverse-proxy without worrying about bugs in the service)

What's wrong with LDAP for users? (I'm trying to think of a negative, and can't).

Yet another service to maintain. If the server is crashing you can't log in, so you need backup UNIX users anyways.

You need backup local admin accounts, not Backups for each user.

Which is how enterprise does things. There are local accounts with root access, but the id's and passwords are tightly controlled.
