Custom

Defguard supports custom providers that allow a code response type in the OpenID authorization flow.

You can also configure a custom OpenID provider. The key thing here is setting up the Base URL correctly. This URL is used to discover all the endpoints required for the authorization flow.

The easiest way of obtaining the Base URL is to find out what is the OpenID .well-known URL of your provider. For example, for Google it's https://accounts.google.com/.well-known/openid-configuration, in this case, the Base URL would be https://accounts.google.com (note the lack of a trailing slash). The part starting with /.well-known is added automatically, so it should be omitted from the Base URL. This is explained in more detail in the Base URL section.

In order to get the Client ID and Client Secret values, refer to the documentation of your custom provider of choice.

When configuring your external OpenID provider, at some point you will need to provide a callback URL, which will redirect the user back to Defguard. This URL is in form of <DEFGUARD_DASHBOARD_URL>/auth/callback. Replace <DEFGUARD_DASHBOARD_URL> with the URL under which your dashboard is accessible, e.g. https://defguard.example.com. If you'd like to use OpenID enrollment through proxy too, make sure to enter an additional URI in the form of <DEFGUARD_ENROLLMENT_URL>/openid/callback.

If you're having issues with your custom provider's base URL, check Defguard's (core) logs. It should say what URL it expected.
