title: Which authentication gem/plugin should I use for Rails 3 running on CouchDB?
body: <p>I'm building a Rails 3 application on CouchDB (using SimplyStored gem) and I'd like to use some existing gem/plugin for authentication, instead of building it from scratch.</p>
  
  <p>Problem is, I can't find anything that works smoothly for CouchDB, everything assumes that you're running on ActiveRecord. Do you have any tips?</p>
