# The Auth Module

## Admin Guide

### Overview

This is a generic module that itself doesn't provide all functions necessary for authentication but provides functions that are needed by all other authentication related modules (so called authentication backends).

We decided to divide the authentication code into several modules because there are now more than one backends (currently database authentication and radius are supported). This allows us to create separate packages so users can install and load only the required functionality. This also allows us to avoid unnecessary dependencies in the binary packages.

### Dependencies

The following modules must be loaded before this module:

- sl - stateless reply.
