To set up a custom OpenID Connect (OIDC) provider with Ory, you can follow these steps: 1. Obtain the necessary configuration details from your OIDC provider: - Client ID - Client Secret - Issuer URL 2. Create a Jsonnet code snippet to map the desired claims from your OIDC provider to the Ory Identity schema. This step is crucial for proper data mapping. 3. Encode the Jsonnet snippet using Base64 or host it at a URL accessible to Ory Network. 4. Add the configuration for your custom OIDC provider to the Ory Identities configuration. Here's an example of how the configuration should look:

yaml selfservice:   methods:     oidc:       config:         providers:           - id: generic # this is `<provider-id>` in the Authorization callback URL             provider: generic             client_id: .... # Replace with your Client ID             client_secret: .... # Replace with your Client Secret             issuer_url: <https://your-provider-issuer-url.com>             mapper_url: "base64://{YOUR_BASE64_ENCODED_JSONNET_HERE}"             # Alternatively, use a URL:             # mapper_url: <https://your-storage-url.com/mapper-file>             scope:               - email               # Add other scopes as needed             claims_source: id_token # set to "userinfo" to read claims from the UserInfo endpoint       enabled: true

5. Update your Ory Identities configuration with the new OIDC provider settings. 6. Set up the redirect URI in your OIDC provider's configuration. The redirect URI should follow this pattern:

http(s)://<domain-of-ory-kratos>:<public-port>/self-service/methods/oidc/callback/<provider-id>

For more detailed information on setting up a custom OIDC provider, you can refer to the [Generic provider documentation](https://www.ory.sh/docs/kratos/social-signin/generic) and the [Self-hosted Kratos configuration guide](https://www.ory.sh/docs/self-hosted/kratos/configuration/oidc). Remember to handle the data mapping carefully to ensure that the required user information is correctly transferred from your OIDC provider to Ory Identities.

Certainly! The Issuer URL is an important component in OpenID Connect (OIDC) configuration. It's the URL of the OpenID Connect server that issues tokens. Here are some examples of Issuer URLs for different providers: 1. For Ory:

<https://your-project-slug.projects.oryapis.com/>

[Ory API Reference](https://www.ory.sh/docs/reference/api) shows an example:

<https://playground.ory.sh/ory-hydra/public/>

2. For GitLab:

<https://gitlab.com>

This example is from the [Github issue about exchanging external OIDC tokens](https://github.com/ory/hydra/issues/3723). 3. For a generic provider:

<https://accounts.google.com>

This example is from the [Ory documentation on generic social sign-in providers](https://www.ory.sh/docs/kratos/social-signin/generic). When configuring your OIDC provider, you would typically use the base URL of the identity provider's authorization server. The exact format may vary depending on the provider you're using. Remember, the Issuer URL is crucial for the OpenID Connect discovery process. It's used to fetch the provider's configuration, including endpoints for authorization, token issuance, and JSON Web Key Sets (JWKS). When setting up your OIDC configuration in Ory, you would include the Issuer URL in the

issuer_url

field of your provider configuration, as shown in the example from the Ory documentation:

yaml providers:   - id: generic     provider: generic     client_id: ....     client_secret: ....     issuer_url: <https://accounts.google.com> # Replace this with your provider's issuer URL

Always ensure you're using the correct Issuer URL for your specific OIDC provider to ensure proper functionality and security of your authentication system.
