# OAuth with Authelia SSO (self-hosted)
|
|
|
|
## Prerequisites
|
|
|
|
This guide assumes you have run and configured [Authelia](https://www.authelia.com/). If you want to get Authelia running quickly, there are example docker-compose files in the [Authelia Github repository](https://github.com/authelia/authelia/tree/master/examples/compose).
|
|
Also this guides assumes you run HedgeDoc via a [Docker container](../../setup/docker.md). Find out how the mentioned config environment variables are mapped to entries in the config file at our [configuration page](../../configuration.md).
|
|
|
|
## Steps
|
|
|
|
1. Set up the necessary OpenID Connect parameters in your Authelia `configuration.yml` as explained in the documentation at <https://www.authelia.com/docs/configuration/identity-providers/oidc.html>.
|
|
2. Make sure to generate safe secrets (such as `LENGTH=64; tr -cd '[:alnum:]' < /dev/urandom | fold -w "${LENGTH}" | head -n 1 | tr -d '\n' ; echo`)
|
|
3. A completed `identity_providers` section of the configuration may look like the following (the chosen Client ID `id` shouldn't actually be this guessable for safety reasons):
|
|
|
|
```yaml
|
|
identity_providers:
|
|
oidc:
|
|
hmac_secret: <hmac secret here> # use docker secrets for this
|
|
issuer_private_key: <issuer private key secret here> # use docker secrets for this
|
|
access_token_lifespan: 1h
|
|
authorize_code_lifespan: 1m
|
|
id_token_lifespan: 1h
|
|
refresh_token_lifespan: 90m
|
|
enable_client_debug_messages: false
|
|
clients:
|
|
- id: HedgeDoc # this should be changed to something more secure
|
|
description: HedgeDoc SSO
|
|
secret: <client secret here>
|
|
public: false
|
|
authorization_policy: two_factor
|
|
audience: []
|
|
scopes:
|
|
- openid
|
|
- email
|
|
- profile
|
|
redirect_uris:
|
|
- https://<your-hedgedoc-url>/auth/oauth2/callback
|
|
grant_types:
|
|
- refresh_token
|
|
- authorization_code
|
|
response_types:
|
|
- code
|
|
response_modes:
|
|
- form_post
|
|
- query
|
|
- fragment
|
|
userinfo_signing_algorithm: none
|
|
```
|
|
|
|
4. Restart Authelia to apply to new configuration and check for any errors in the log
|
|
5. In the `docker-compose.yml` of HedgeDoc add the following environment variables (you can choose different attributes for e.g. the display name - all available attributes you can find in the [scope definitions](https://www.authelia.com/docs/configuration/identity-providers/oidc.html#scope-definitions)):
|
|
|
|
```yaml
|
|
- CMD_URL_ADDPORT=false
|
|
- CMD_PROTOCOL_USESSL=true
|
|
- CMD_OAUTH2_PROVIDERNAME=Authelia
|
|
- CMD_OAUTH2_CLIENT_ID=HedgeDoc
|
|
- CMD_OAUTH2_CLIENT_SECRET=<client secret here>
|
|
- CMD_OAUTH2_SCOPE=openid email profile
|
|
- CMD_OAUTH2_USER_PROFILE_USERNAME_ATTR=sub
|
|
- CMD_OAUTH2_USER_PROFILE_DISPLAY_NAME_ATTR=name
|
|
- CMD_OAUTH2_USER_PROFILE_EMAIL_ATTR=email
|
|
- CMD_OAUTH2_USER_PROFILE_URL=https://<your-authelia-url>/api/oidc/userinfo
|
|
- CMD_OAUTH2_TOKEN_URL=https://<your-authelia-url>/api/oidc/token
|
|
- CMD_OAUTH2_AUTHORIZATION_URL=https://<your-authelia-url>/api/oidc/authorize
|
|
```
|
|
|
|
6. Run `docker-compose up -d` on HedgeDoc to apply your settings.
|
|
7. Sign in to your HedgeDoc using your Authelia login
