Development setup to test SSO

SSO support for Vaultwarden is currently in development. The following describes a docker-compose based setup for locally testing these changes.

[!WARNING] ONLY USE FOR TESTING SSO, SETUP IS INSECURE

Setup

• Checkout the SSO branch
• Create docker-compose.yml with the following contents:

services:
  vaultwarden:
    build: .
    environment:
      DOMAIN: "http://localhost:8000"
      I_REALLY_WANT_VOLATILE_STORAGE: "true"
      SSO_ENABLED: "true"
      SSO_CLIENT_ID: "client"
      SSO_CLIENT_SECRET: "clientsecret"
      SSO_AUTHORITY: "http://auth.test:8080/mock"
    ports:
      - 127.0.0.1:8000:80

  mock-oauth2:
    image: ghcr.io/navikt/mock-oauth2-server:0.5.10
    hostname: "auth.test"
    ports:
      - 127.0.0.1:8080:8080

• Add auth.test to your systems host file: echo "127.0.0.1 auth.test" | sudo tee -a /etc/hosts
• Build vaultwarden: docker compose build

Testing

• Start the services: docker compose up
• Go to http://localhost:8000/#/sso, enter any string as identifier, click "Log in".
• On the Mock Auth2 Server Sign-in-Page, enter any string for user/subject and add the email you want to test in the claims field like so: {"email": "[email protected]"}
• If everything went according to plan, you will be asked for a master password.
