When I try to use the views-based log-in screen for a public session, the Terms of Service doesn't load correctly ("Oops, something went wrong") and the log-in screen goes back to the initial view.

You have to specify a ToS in the admin console to have the ToS screen show up.

Re#11: Thanks Michael. Does the webui version load ToS screen correctly?
