I’ve just implemented [Discourse SSO](https://meta.discourse.org/t/13045?silent=true) (to my Identity Server 4 powered IDP, yay).

I take it there’s no single-sign-out capability, i.e. a ping to the IDP to let it know the user has signed-out, so they can be signed-out of the IDP and any other apps as well?

The situation where someone uses a public computer, signs-in to the IDP, uses Discourse, then signs-out of Discourse thinking they’re done, when actually they’re stilled signed-in with the IDP, which would allow anyone using the computer next to just click Sign-in to Discourse again and be authenticated without prompt concerns me.
