For I ♥ DNN, we wanted to bring the barrier to entry very, very low, so that anyone could join the conversation simply and easily, without having to create yet another website account. To that end, we wanted to allow folks to sign in with their existing social network logins: Facebook, Twitter, and Google. Since these are provided with DNN, we assumed it would be fairly simple to achieve our vision. However, we ran into a handful of obstacles that we worked to overcome in implementing the core social login providers, ultimately copying and extending them to better meet our needs.
