Basic RADIUS Server for node.js for Google LDAP Service and WPA2 Enterprise WLAN Authentification.
|
|
|
|
- supports LDAP Authentification Backend
|
|
- supports WPA2 Enterprise (TTLS over PAP)
|
|
|
|
Protect your WIFI access with a username and password by a credential provider you already use!
|
|
|
|
Authentication tested with Windows, Linux, Android and Apple devices.
|
|
|
|
# Quick start
|
|
|
|
1. Install node js => 13.10.1
|
|
- easiest way is to install a node js version from nodejs.org or run "npx n latest" to install latest version.
|
|
2. Check out the config options, e.g. for google ldap, download your certificates from http://admin.google.com/ -> Apps -> LDAP -> Client
|
|
download the files and name them "ldap.gsuite.key" and "ldap.gsuite.crt" accordingly (Ensure you have activated your newly created LDAP Client in Google Admin).
|
|
3. Switch to this directory and run "npx radius-server -s YourRadiusSecret"
|
|
3. Switch to this directory and run "npx radius-server -s YourRadiusSecret"
|
|
4. Log into your WLAN Controller and configure the radius server to your newly running radius
|
|
5. On your clients, just connect to the WLAN, the clients should figure out the correct method by their own,
|
|
if they don't use: WPA2-Enterprise -> EAP-TTLS -> PAP / CHAP
|
|
6. Log in via your google credentials (email + password, ... e.g. youremail@yourcompany.com)
|
|
|
|
## Known Issues / Disclaimer
|
|
|
|
Support for this has landed in node 13.10.1, therefore ensure you have installed at least this node version.
|
|
|
|
- MD5 Challenge not implenented, but RFC says this is mandatory ;-)
|
|
- Inner Tunnel does not act differently, even though spec says that EAP-message are not allowed to get fragmented,
|
|
this is not a problem right now, as the messages of the inner tunnel are small enough, but it could be a bug in the future.
|
|
ways to approach this: refactor that the inner tunnel can set max fragment size, or rebuild eap fragments in ttls after inner tunnel response

## Motivation
|
|
|
|
### Why not Freeradius?
|
|
|
|
There are several reasons why I started implementing this radius server in node js. We are using
|
|
freeradius right now, but have several issues which are hard to tackle due to the reason that freeradius
|
|
is a complex software and supports many uses cases. It is also written in C++ and uses threads behind the scene.
|
|
Therefore it's not easy to extend or modify it, or even bring new feature in.
|
|
The idea of this project is to make a super simple node radius server, which is async by default. No complex
|
|
thread handling, no other fancy thing. The basic goal is to make WPA2 authenticiation easy again.
|
|
|
|
### 802.1x protocol in node
|
|
|
|
Another motivation is that it is very exciting to see how wireless protocols have evolved, and see
|
|
how a implementation like TTLS works.
|
|
|
|
### Few alternatives (only non-free ones like Jumpcloud...)
|
|
|
|
Furthermore there are few alternatives out there, e.g. jumpcloud is non-free and I couldn't find many others.
|
|
|
|
### Vision
|
|
|
|
As soon as I understood the TTLS PAP Tunnel approach, I had this vision of making Wlan Authentification easy
|
|
for everyone. Why limit it to something "complex" like LDAP and co. This library aims to make it easy for everyone
|
|
to implement either their own authentication mechanismus (e.g. against a database), or provides some mechansimns
|
|
out of the box (e.g. imap, static, ldap,..).
|
|
|
|
## Installation
|
|
|
|
npm install
|
|
npm run build
|
|
|
|
## Introduction
|
|
|
|
This app provides a radius server to authenticate against google's SLDAP service. To get this running
|
|
you need:
|
|
|
|
1. Running LDAP Service (E.g. Google Suite Enterprise or Gloud Identity Premium)
|
|
2. Optional: Create your own SSL certificate (e.g. self signed via npm run create-certificate)
|
|
3. Check config.js and adapt to your needs
|
|
|
|
- configure authentication:
|
|
set authenticaiton to one of the provided authenticators.
|
|
|
|
```js
|
|
var config = {
|
|
// ....
|
|
authentication: 'GoogleLDAPAuth',
|
|
authenticationOptions: {
|
|
base: 'dc=hokify,dc=com'
|
|
}
|
|
};
|
|
```
|
|
|
|
- set radius secret
|
|
|
|
4. Install und build server: npm install && npm run build
|
|
5. Start server "npm run start"
|
|
|
|
## Configuration
|
|
|
|
For authentication see [Authentication Details](src/auth/README.md).
|
|
For general config options run with --help or see see [config.js](config.js) in root.
|
|
|
|
## Usage
|
|
|
|
Ensure you have installed latest node version (>= 13.10.1) and run:
|
|
|
|
npm run start
|
