We are planning on adding an OAuth2 adapter to the JS library for 1.3.0. We are going to code against the google OAuth2 playground stuff, but trying to follow the spec as much as possible and try to be as generic as we can.
I'm not sure if this should be an "adapter" or something different. If it is an adapter of the Authentication plugin( not sure what we are calling the different pieces. pipeline, data manager, etc.), then we should expect to see authentication methods( enroll, login, logout ), but i think this "adapter" should be much more than that.
It should be used to connect to secured services( api ) that a user allows, such as GCM for chrome or the google+ platform, or some other enterprisey thing.
I'm wondering if this should be a standalone thing. I kind of like this idea so when we do social login, which will most likely have OAuth2, we can just access it.
