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)
I think you’re missing the point of LDAP then. It’s a centralized directory used for querying information. It’s not necessarily about user information, but can be anything.
What you’re asking for is akin to locally hosting a SQL server that other machines can talk to? Then it’s just a server. Start an LDAP server somewhere, then talk to it. That’s how it works.
If you don’t want a network service for this purpose, then don’t use LDAP. If you want a bunch of users to exist on many machines without having to manually create them, then use LDAP, or a system configuration tool that creates and keeps them all eventually consistent.
