## Tested Versions
|
|
|
|
* [Authelia]
|
|
* [v4.35.6](https://github.com/authelia/authelia/releases/tag/v4.35.6)
|
|
|
|
## Before You Begin
|
|
|
|
You are required to utilize a unique client id and a unique and random client secret for all [OpenID Connect] relying
|
|
parties. You should not use the client secret in this example, you should randomly generate one yourself. You may also
|
|
choose to utilize a different client id, it's completely up to you.
|
|
|
|
This example makes the following assumptions:
|
|
|
|
* __Cloudflare Team Name:__ `example-team`
|
|
* __Authelia Root URL:__ `https://auth.example.com`
|
|
* __Client ID:__ `cloudflare`
|
|
* __Client Secret:__ `cloudflare_client_secret`
|
|
|
|
*__Important Note:__ Cloudflare does not properly URL encode the secret per [RFC6749 Appendix B] at the time this
|
|
article was last updated (noted at the bottom). This means you'll either have to use only alphanumeric characters for
|
|
the secret or URL encode the secret yourself.*
|
|
|
|
[RFC6749 Appendix B]: https://www.rfc-editor.org/rfc/rfc6749#appendix-B
|
|
|
|
## Configuration
|
|
|
|
### Application
|
|
|
|
*__Important Note:__ It is a requirement that the Authelia URL's can be requested by Cloudflare's servers. This usually
|
|
means that the URL's are accessible to foreign clients on the internet. There may be a way to configure this without
|
|
accessibility to foreign clients on the internet on Cloudflare's end but this is beyond the scope of this document.*
|
|
|
|
To configure [Cloudflare Zero Trust] to utilize Authelia as an [OpenID Connect] Provider:
|
|
|
|
1. Visit the [Cloudflare Zero Trust Dashboard](https://dash.teams.cloudflare.com)
|
|
2. Visit `Settings`
|
|
3. Visit `Authentication`
|
|
4. Under `Login nethods` select `Add new`
|
|
5. Select `OpenID Connect`
|
|
6. Set the following values:
|
|
1. Name: `Authelia`
|
|
2. App ID: `cloudflare`
|
|
3. Client Secret: `cloudflare_client_secret`
|
|
4. Auth URL: `https://auth.example.com/api/oidc/authorization`
|
|
5. Token URL: `https://auth.example.com/api/oidc/token`
|
|
6. Certificate URL: `https://auth.example.com/jwks.json`
|
|
7. Enable `Proof Key for Code Exchange (PKCE)`
|
|
8. Add the following OIDC Claims: `preferred_username`, `mail`
|
|
7. Click Save
|
|
|
|
### Authelia
|
|
|
|
The following YAML configuration is an example __Authelia__
|
|
[client configuration](../../../configuration/identity-providers/open-id-connect.md#clients) for use with [Cloudflare]
|
|
which will operate with the above example:
|
|
|
|
```yaml
|
|
- id: cloudflare
|
|
description: Cloudflare ZeroTrust
|
|
secret: cloudflare_client_secret
|
|
public: false
|
|
authorization_policy: two_factor
|
|
redirect_uris:
|
|
- https://example-team.cloudflareaccess.com/cdn-cgi/access/callback
|
|
scopes:
|
|
- openid
|
|
- profile
|
|
- email
|
|
userinfo_signing_algorithm: none
|
|
```
|
