the stack

As far as i am aware of, all is setup as described in the documentation, and it works on oauth2-proxy:v7.2.1 but not on v7.3.0 and i could pin point it to the commit

• keycloak
  • http://localhost:8080
  • testclient setuped liked described in the docs
  • testuser test with the password test
  • admin user admin with the password change_me
• oauth2-proxy
  • https://localhost:4190
  • setup with keycloak-oidc
  • TLS with self signed certificates
• upstream (httpbin)

howto reproduce

1. start the stack with docker-compose up -d
2. open https://localhost:4190 in a private window
3. login with user test and password test
4. after login open https://localhost:4190/oauth2/userinfo
5. the user field is empty
6. close the private window
7. switch to v7.2.1 with git checkout works
8. and repeat the steps 1-4
9. now you see a username
