**Authelia** is a complete HTTP 2-factor authentication server for proxies like
|
|
nginx. It has been made to work with nginx [auth_request] module and is currently
|
|
used in production to secure internal services in a small docker swarm cluster.

|
|
address.

|
|
|
|
## Deployment
|
|
|
|
If you don't have any LDAP and/or nginx setup yet, I advise you to follow the
|
|
[Getting Started](#Getting-started) section. That way, you can test it right away
|
|
without even configuring anything.
|
|
|
|
Otherwise, here are the available steps to deploy **Authelia** on your machine given
|
|
your configuration file is **/path/to/your/config.yml**. Note that you can create your
|
|
own the configuration file from [config.template.yml] at the root of the repo.
|
|
|
|
### With NPM
|
|
|
|
npm install -g authelia
|
|
authelia /path/to/your/config.yml
|
|
|
|
### With Docker
|
|
|
|
docker pull clems4ever/authelia
|
|
docker run -v /path/to/your/config.yml:/etc/authelia/config.yml -v /path/to/data/dir:/var/lib/authelia clems4ever/authelia
|
|
|
|
where **/path/to/data/dir** is the directory where all user data will be stored.
|
|
|
|
## Getting started
|
|
|
|
The provided example is docker-based so that you can deploy and test it very
|
|
quickly.
|
|
|
|
### Pre-requisites
|
|
|
|
#### npm
|
|
Make sure you have npm and node installed on your computer.
|
|
|
|
#### Docker
|
|
Make sure you have **docker** and **docker-compose** installed on your machine.
|
|
For your information, here are the versions that have been used for testing:
|
|
|
|
docker --version
|
|
|
|
gave *Docker version 17.03.1-ce, build c6d412e*.
|
|
|
|
docker-compose --version
|
|
|
|
gave *docker-compose version 1.14.0, build c7bdf9e*.
|
|
|
|
#### Available port
|
|
Make sure you don't have anything listening on port 8080 (webserver) and 8085 (webmail).
|
|
|
|
#### Subdomain aliases
|
|
|
|
Add the following lines to your **/etc/hosts** to alias multiple subdomains so that nginx can redirect request to the correct virtual host.
|
|
|
|
127.0.0.1 home.test.local
|
|
127.0.0.1 public.test.local
|
|
127.0.0.1 dev.test.local
|
|
127.0.0.1 admin.test.local
|
|
127.0.0.1 mx1.mail.test.local
|
|
127.0.0.1 mx2.mail.test.local
|
|
127.0.0.1 auth.test.local
|
|
|
|
### Run it!
|
|
|
|
Deploy the **Authelia** example with one of the following commands:
|
|
|
|
Build Docker container from current commit:
|
|
|
|
npm install --only=dev
|
|
./node_modules/.bin/grunt build-dist
|
|
./scripts/example-commit/deploy-example.sh
|
|
|
|
Use provided container on [DockerHub](https://hub.docker.com/r/clems4ever/authelia/):
|
|
|
|
./scripts/example-dockerhub/deploy-example.sh
|
|
|
|
After few seconds the services should be running and you should be able to visit
|
|
[https://home.test.local:8080/](https://home.test.local:8080/).
|
|
|
|
When accessing the login page, a self-signed certificate exception should appear,
|
|
it has to be trusted before you can get to the target page. The certificate
|
|
must also be trusted for each subdomain, therefore it is normal to see the exception
|
|
several times.
|
|
|
|
Below is what the login page looks like:

|
## Features in details
|
|
|
|
### First factor using an LDAP server
|
|
**Authelia** uses an LDAP server as the backend for storing credentials.
|
|
When authentication is needed, the user is redirected to the login page which
|
|
corresponds to the first factor. Authelia tries to bind the username and password
|
|
against the configured LDAP backend.
|
|
|
|
You can find an example of the configuration of the LDAP backend in [config.template.yml].
|
|
|
|

|
|
|
|
|
|
### Second factor with TOTP
|
|
In **Authelia**, you can register a per user TOTP (Time-Based One Time Password) secret before
|
|
authenticating. To do that, you need to click on the register button. It will
|
|
send a link to the user email address stored in LDAP. Since this is an example, the email is sent
|
|
to a fake email address you can access from the webmail at [http://localhost:8085](http://localhost:8085).
|
|
Click on **Continue** and you'll get your secret in QRCode and Base32 formats. You can use
|
|
[Google Authenticator]
|
|
to store them and get the generated tokens with the app.
|
|
|
|

|
|
|
|
### Second factor with U2F security keys
|
|
**Authelia** also offers authentication using U2F (Universal 2-Factor) devices like [Yubikey](Yubikey)
|
|
USB security keys. U2F is one of the most secure authentication protocol and is
|
|
already available for Google, Facebook, Github accounts and more.
|
|
|
|
Like TOTP, U2F requires you register your security key before authenticating.
|
|
To do so, click on the register button. This will send a link to the
|
|
user email address. Since this is an example, the email is sent
|
|
to a fake email address you can access from the webmail at [http://localhost:8085](http://localhost:8085).
|
|
Click on **Continue** and you'll be asking to touch the token of your device
|
|
to register. Upon successful registration, you can authenticate using your U2F
|
|
device by simply touching the token. Easy, right?!
|
|
|
|

|
|
|
|
### Password reset
|
|
With **Authelia**, you can also reset your password in no time. Click on the
|
|
**Forgot password?** link in the login page, provide the username of the user requiring
|
|
a password reset and **Authelia** will send an email with an link to the user
|
|
email address. For the sake of the example, the email is delivered in a fake webmail deployed
|
|
for you and accessible at [http://localhost:8085](http://localhost:8085).
|
|
Paste the link in your browser and you should be able to reset the password.

|
|
|
|
### Access Control
|
|
With **Authelia**, you can define your own access control rules for finely restricting
|
|
user access to some resources and subdomains. Those rules are defined and fully documented
|
|
in the configuration file. They can apply to users, groups or everyone.
|
|
Check out [config.template.yml] to see how they are defined.
|
|
|
|
### Session management with Redis
|
|
When your users authenticate against Authelia, sessions are stored in a Redis key/value store. You can specify your own Redis instance in [config.template.yml].
|
|
|
|
## Documentation
|
|
### Authelia configuration
|
|
The configuration of the server is defined in the file
|
|
[config.template.yml]. All the details are documented there.
|
|
You can specify another configuration file by giving it as first argument of
|
|
**Authelia**.
|
|
|
|
authelia config.custom.yml
|
|
|
|
### API documentation
|
|
There is a complete API documentation generated with
|
|
[apiDoc](http://apidocjs.com/) and embedded in the repo under the **doc/**
|
|
directory. Simply open index.html locally to watch it.
