OAuth Provider Service and Rails 3

I am trying to look into开发者_StackOverflow中文版 setting up an OAuth Provider Server with Rails 3 but can't seem to find anything out there to accomplish this.

I am also a newb when it comes to oauth, so excuse my ignorance.

When setting up an oauth server do I need to already have an oauth account at somewhere like agree2.com? Or can I just use my own server?

If you set up an OAuth server, you don't need to have an account somewhere else, that is the whole point of a server. It's a little bit outdated, but perhaps it's a good starting point: http://stakeventures.com/articles/2007/11/26/how-to-turn-your-rails-site-into-an-oauth-provider
