Walled in by the wonderful Wonderwall

Basic toy API in Ktor that showcases usage of Wonderwall from a backend application's point of view. This is not a production-ready application.

Requires (almost) all requests received to contain a Bearer token issued by the configured Identity Provider.

ID-porten:

• Expects the token to contain a claim aud with a value that matches the client ID of the application's client.
• Supports Token Exchange using TokenX.

Azure AD:

• Expects the token to contain a claim aud with a value that matches the client ID of the application's client.
• Supports the On-Behalf-Of flow.
• Supports the Client Credentials flow.

Maskinporten:

• Requires login with Azure AD.
• API for fetching machine-to-machine tokens from Maskinporten.

• /internal/* - unauthenticated
  • /internal/is_alive
  • /internal/is_ready
• /api/* - requires a Bearer JWT access token in the Authorization header
  • /api/headers - prints all headers in the request
  • /api/me - prints all claims for the token received
  • /api/obo?aud=<cluster>:<namespace>:<app> - exchanges the subject token for the given aud (audience)
  • /api/m2m?aud=<cluster>:<namespace>:<app> - (Azure only) fetches a machine-to-machine token for the given aud (audience)

Requires JDK installed, minimum version 21.

Start required dependencies:

docker-compose up -d

• wonderwall @ http://localhost:4000 (reverse proxy for openid connect)
• texas @ http://localhost:3000 (token exchange / introspection service)
• mock-oauth2-server @ http://localhost:8080 (mock identity provider)

Run wonderwalled for the desired identity provider:

./gradlew wonderwalled-azure:run

or

./gradlew wonderwalled-idporten:run

or

./gradlew wonderwalled-maskinporten:run

Visit the endpoints at localhost:4000 (i.e. via Wonderwall as a reverse proxy):

• http://localhost:4000
• http://localhost:4000/api/headers
• http://localhost:4000/api/me
• http://localhost:4000/api/obo?aud=cluster:namespace:app
• http://localhost:4000/api/m2m?aud=cluster:namespace:app
