I can't seem to find anything about migrating away from openid for omniauth users? Is this as simple as changing the redirect url?
require "openid/store/filesystem"
require "omniauth-google-oauth2"
config.omniauth :google_apps,
store: OpenID::Store::Filesystem.new('/tmp'),
domain: "example.com",
identifier: "https://www.google.com/accounts/o8/id"
I ended up using gem omniauth-google-oauth2
.
The ReadMe explains how to set it up.
gem omniauth-google-apps
is now deprecated and no longer maintained. It won't work after April 20, 2015 when google stops supporting openid.
