I'm using Google provider.

Everything works fine except that i get occasional 403 on both the http://hello-world.sso.localtest.me/, http://httpbin.sso.localtest.me/. After every 403, refreshing the page gets to to work. I see user is no longer in valid groups message whenever the backends throws the 403 error.

Any pointers on this?

The error message is as follows


sso-proxy_1    | {"error":null,"level":"error","msg":"no longer authorized after validation period","remote_address":"172.21.0.1","service":"sso-proxy","time":"2019-12-03 07:25:00.579","user":"xx@gmail.com"}

The upstream.yml config is as follows

$ cat upstream_configs.yml 
- service: httpbin
  default:
    from: httpbin.sso.localtest.me
    to: http://httpbin:8080

- service: hello-world
  default:
    from: hello-world.sso.localtest.me
    to: http://hello-world/

@Jusshersmith ,

The problem starts after SESSION_VALID_TTL expires. The proxy tries to issue /google/profile call to the sso authenticator like "/google/profile?client_id=%3D&email=%40gmail.com&groups=". It seems like becoz of the empty groups parameter, the code flow enters into https://github.com/buzzfeed/sso/blob/99e69f8f57cc4a5e64e467665cc6b8f46b11e511/internal/proxy/oauthproxy.go#L763? That seems to lead to the 403 error.

Any update on the fix? I'm seeing this error with the quickstart as well.

Jusshersmith commented 4 years ago

Hi!

This should be fixed now. Sorry for the massive delay getting this resolved. Unfortunately the original fix had some complications, which knocked this back a bit!

Please do re-open if you're still seeing this error.
