Has anyone been able to get this to work in R4?
excellent, thanks!
Does this work in Rails 4?
yes
This is a nice example. However, how do you get past the "password must be present" validation that Clearance adds, when creating from OmniAuth?
Fantastic example. Thanks!

Do you have the markup for the view to sign-up with omniauth?
