## Tested Versions
|
|
|
|
* [Authelia]
|
|
* [v4.38.0](https://github.com/authelia/authelia/releases/tag/v4.38.0)
|
|
|
|
{{% oidc-common %}}
|
|
|
|
### Assumptions
|
|
|
|
This example makes the following assumptions:
|
|
|
|
* __Cloudflare Team Name:__ `example-team`
|
|
* __Authelia Root URL:__ `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/`
|
|
* __Client ID:__ `cloudflare`
|
|
* __Client Secret:__ `insecure_secret`
|
|
|
|
Some of the values presented in this guide can automatically be replaced with documentation variables.
|
|
|
|
{{< sitevar-preferences >}}
|
|
|
|
{{< callout context="caution" title="Important Note" icon="outline/alert-triangle" >}}
|
|
[Cloudflare Zero Trust](https://www.cloudflare.com/products/zero-trust/) does not properly URL encode the secret per [RFC6749 Appendix B](https://datatracker.ietf.org/doc/html/rfc6749#appendix-B) at the
|
|
time this article was last modified (noted at the bottom). This means you'll either have to use only alphanumeric
|
|
characters for the secret or URL encode the secret yourself.

## Configuration
|
|
|
|
### Authelia
|
|
|
|
The following YAML configuration is an example __Authelia__ [client configuration] for use with [Cloudflare] which will
|
|
operate with the application example:
|
|
|
|
```yaml {title="configuration.yml"}
|
|
identity_providers:
|
|
oidc:
|
|
## The other portions of the mandatory OpenID Connect 1.0 configuration go here.
|
|
## See: https://www.authelia.com/c/oidc
|
|
clients:
|
|
- client_id: 'cloudflare'
|
|
client_name: 'Cloudflare ZeroTrust'
|
|
client_secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng' # The digest of 'insecure_secret'.
|
|
public: false
|
|
authorization_policy: 'two_factor'
|
|
redirect_uris:
|
|
- 'https://example-team.cloudflareaccess.com/cdn-cgi/access/callback'
|
|
scopes:
|
|
- 'openid'
|
|
- 'profile'
|
|
- 'email'
|
|
userinfo_signed_response_alg: 'none'
|
|
```
|
|
|
|
### Application
|
|
|
|
{{< callout context="caution" title="Important Note" icon="outline/alert-triangle" >}}
|
|
It is a requirement that the Authelia URL's can be requested by Cloudflare's servers. This usually
|
|
means that the URLs 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.
