#openid_begin ⇒ Object

We land here from the openid_login_form and if we can find a matching OpenID server we redirect the user to it, the browser will return to openid_complete when the authentication is complete.

  else
    # what the hell is @form_text ?
  end

rescue OpenID::OpenIDError => ex
  flash[:error] = "Discovery failed for #{url}: #{ex}"
  raw_redirect Rs(:/)
end

#openid_complete ⇒ Object

After having authenticated at the OpenID server browsers are redirected back here and on success we set the session[:identity] and a little default flash message. Then we redirect to wherever session[:entry] points us to, which was set on openid_begin to the referrer

TODO:

- maybe using StackHelper, but this is a really minimal overlap?

#openid_login_form(caption = "login") ⇒ Object

Simple form for use or overwriting. Has to provide the same functionality when overwritten or directly embedded into a page.
