### Dex
[Dex][dex-idp] is a simple, open-source OpenID Connect Provider.
Although it is designed to help building a full-blown provider with an
external database, it can be configured with static passwords in a config file.
Follow the [Getting Started guide](https://dexidp.io/docs/getting-started/)
to install Dex.
Edit `examples/config-dev.yaml` config file from the Dex repo to add a client:
```yaml
staticClients:
- id: synapse
secret: secret
redirectURIs:
- '[synapse public baseurl]/_synapse/client/oidc/callback'
name: 'Synapse'
```
Run with `dex serve examples/config-dev.yaml`.
Synapse config:
```yaml
oidc_providers:
- idp_id: dex
idp_name: "My Dex server"
skip_verification: true # This is needed as Dex is served on an insecure endpoint
issuer: "http://127.0.0.1:5556/dex"
client_id: "synapse"
client_secret: "secret"
scopes: ["openid", "profile"]
user_mapping_provider:
config:
localpart_template: "{{ user.name }}"
display_name_template: "{{ user.name|capitalize }}"
```
### Keycloak
[Keycloak][keycloak-idp] is an opensource IdP maintained by Red Hat.
Keycloak supports OIDC Back-Channel Logout, which sends logout notification to Synapse, so that Synapse users get logged out when they log out from Keycloak.
This can be optionally enabled by setting `backchannel_logout_enabled` to `true` in the Synapse configuration, and by setting the "Backchannel Logout URL" in Keycloak.
Follow the [Getting Started Guide](https://www.keycloak.org/getting-started) to install Keycloak and set up a realm.
1. Click `Clients` in the sidebar and click `Create`
2. Fill in the fields as below:
| Field | Value |
|-----------|-----------|
| Client ID | `synapse` |
| Client Protocol | `openid-connect` |
### Apple
3. Click `Save`
4. Fill in the fields as below:
Configuring "Sign in with Apple" (SiWA) requires an Apple Developer account.
| Field | Value |
|-----------|-----------|

| Client Protocol | `openid-connect` |
| Access Type | `confidential` |
| Valid Redirect URIs | `[synapse public baseurl]/_synapse/client/oidc/callback` |
| Backchannel Logout URL (optional) | `[synapse public baseurl]/_synapse/client/oidc/backchannel_logout` |
| Backchannel Logout Session Required (optional) | `On` |
You will need to create a new "Services ID" for SiWA, and create and download a
private key with "SiWA" enabled.
5. Click `Save`
6. On the Credentials tab, update the fields:
As well as the private key file, you will need:
* Client ID: the "identifier" you gave the "Services ID"
* Team ID: a 10-character ID associated with your developer account.
* Key ID: the 10-character identifier for the key.
| Field | Value |
|-------|-------|
| Client Authenticator | `Client ID and Secret` |
[Apple's developer documentation](https://help.apple.com/developer-account/?lang=en#/dev77c875b7e)
has more information on setting up SiWA.
7. Click `Regenerate Secret`
8. Copy Secret

### LemonLDAP
### Dex
[LemonLDAP::NG][lemonldap] is an open-source IdP solution.
[Dex][dex-idp] is a simple, open-source OpenID Connect Provider.
Although it is designed to help building a full-blown provider with an
external database, it can be configured with static passwords in a config file.
1. Create an OpenID Connect Relying Parties in LemonLDAP::NG
2. The parameters are:
- Client ID under the basic menu of the new Relying Parties (`Options > Basic >
Client ID`)
- Client secret (`Options > Basic > Client secret`)
- JWT Algorithm: RS256 within the security menu of the new Relying Parties
(`Options > Security > ID Token signature algorithm` and `Options > Security >
Access Token signature algorithm`)
- Scopes: OpenID, Email and Profile
- Allowed redirection addresses for login (`Options > Basic > Allowed
redirection addresses for login` ) :
`[synapse public baseurl]/_synapse/client/oidc/callback`
Follow the [Getting Started guide](https://dexidp.io/docs/getting-started/)
to install Dex.
Edit `examples/config-dev.yaml` config file from the Dex repo to add a client:
```yaml
staticClients:
- id: synapse
secret: secret
redirectURIs:
- '[synapse public baseurl]/_synapse/client/oidc/callback'
name: 'Synapse'
```
Run with `dex serve examples/config-dev.yaml`.

### GitHub
### Django OAuth Toolkit
[GitHub][github-idp] is a bit special as it is not an OpenID Connect compliant provider, but
just a regular OAuth2 provider.
[django-oauth-toolkit](https://github.com/jazzband/django-oauth-toolkit) is a
Django application providing out of the box all the endpoints, data and logic
needed to add OAuth2 capabilities to your Django projects. It supports
[OpenID Connect too](https://django-oauth-toolkit.readthedocs.io/en/latest/oidc.html).
The [`/user` API endpoint](https://developer.github.com/v3/users/#get-the-authenticated-user)
can be used to retrieve information on the authenticated user. As the Synapse
login mechanism needs an attribute to uniquely identify users, and that endpoint
does not return a `sub` property, an alternative `subject_claim` has to be set.
Configuration on Django's side:
1. Create a new OAuth application: [https://github.com/settings/applications/new](https://github.com/settings/applications/new).
2. Set the callback URL to `[synapse public baseurl]/_synapse/client/oidc/callback`.
1. Add an application: `https://example.com/admin/oauth2_provider/application/add/` and choose parameters like this:
* `Redirect uris`: `https://synapse.example.com/_synapse/client/oidc/callback`
* `Client type`: `Confidential`
* `Authorization grant type`: `Authorization code`
* `Algorithm`: `HMAC with SHA-2 256`
2. You can [customize the claims](https://django-oauth-toolkit.readthedocs.io/en/latest/oidc.html#customizing-the-oidc-responses) Django gives to synapse (optional):
<details>
<summary>Code sample</summary>
Synapse config:
```python
class CustomOAuth2Validator(OAuth2Validator):
def get_additional_claims(self, request):
return {
"sub": request.user.email,
"email": request.user.email,
"first_name": request.user.first_name,
"last_name": request.user.last_name,
}
```
</details>
Your synapse config is then:
```yaml
oidc_providers:
- idp_id: github
idp_name: Github
idp_brand: "github" # optional: styling hint for clients
- idp_id: django_example
idp_name: "Django Example"
issuer: "https://example.com/o/"
client_id: "your-client-id" # CHANGE ME
client_secret: "your-client-secret" # CHANGE ME
scopes: ["openid"]
user_profile_method: "userinfo_endpoint" # needed because oauth-toolkit does not include user information in the authorization response
user_mapping_provider:
config:
localpart_template: "{{ user.email.split('@')[0] }}"
display_name_template: "{{ user.first_name }} {{ user.last_name }}"
email_template: "{{ user.email }}"
```
### Facebook
0. You will need a Facebook developer account. You can register for one
[here](https://developers.facebook.com/async/registration/).
1. On the [apps](https://developers.facebook.com/apps/) page of the developer
console, "Create App", and choose "Build Connected Experiences".
2. Once the app is created, add "Facebook Login" and choose "Web". You don't
need to go through the whole form here.
3. In the left-hand menu, open "Products"/"Facebook Login"/"Settings".
* Add `[synapse public baseurl]/_synapse/client/oidc/callback` as an OAuth Redirect
URL.
4. In the left-hand menu, open "Settings/Basic". Here you can copy the "App ID"
and "App Secret" for use below.
Synapse config:

### Google
[Google][google-idp] is an OpenID certified authentication and authorisation provider.
1. Set up a project in the Google API Console (see
[documentation](https://developers.google.com/identity/protocols/oauth2/openid-connect#appsetup)).
3. Add an "OAuth Client ID" for a Web Application under "Credentials".
4. Copy the Client ID and Client Secret, and add the following to your synapse config:
```yaml
oidc_providers:
- idp_id: google
idp_name: Google
idp_brand: "google" # optional: styling hint for clients
issuer: "https://accounts.google.com/"
client_id: "your-client-id" # TO BE FILLED
client_secret: "your-client-secret" # TO BE FILLED
scopes: ["openid", "profile", "email"] # email is optional, read below
user_mapping_provider:
config:
localpart_template: "{{ user.given_name|lower }}"
display_name_template: "{{ user.name }}"
email_template: "{{ user.email }}" # needs "email" in scopes above
```
4. Back in the Google console, add this Authorized redirect URI: `[synapse
public baseurl]/_synapse/client/oidc/callback`.

Facebook do have an [OIDC discovery endpoint](https://www.facebook.com/.well-known/openid-configuration),
but it has a `response_types_supported` which excludes "code" (which we rely on, and
is even mentioned in their [documentation](https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow#login)),
so we have to disable discovery and configure the URIs manually.
1. Setup a developer account on [Twitch](https://dev.twitch.tv/)
2. Obtain the OAuth 2.0 credentials by [creating an app](https://dev.twitch.tv/console/apps/)
