Shibboleth v3 logout functionality

[Cantor, Scott]

> I'm not sure how to get similar functionality now using v3.

You can't, at least short of building your own webflow to do logout the way you want. We don't currently include any support for transitioning away from the IDP, at least not dynamically. The IdP is the endpoint of the flow and renders the UI itself, and that UI is limited today to the interactions it comes with.
