title: Oauth2 refresh_token confusion
body: <p>Im using a 3rd party api server side, which generates an <code>access_token</code> and a <code>refresh_token</code> as per normal via a <code>grant_type=password</code> request. I'm confused because this api does not appear to support <code>grant_type=refresh_token</code> - I keep getting the unsupported grant type error. Does it even matter, when you can just handle unauthorized errors by re-firing the password grant request? is this typical for 3rd party api use?</p>
