Rails 3 multiple accounts authentication solution

Question

I am searching for a working solution of authentication on Rails 3 with the following features:

• account types: standard login, facebook connect, openid, oauth

• one user may have (and link) multiple accounts (EG a user attach both Wordpress and Google OpenID accounts)

A working example of Rails app implementing them would be perfect.

Answer 1

You could take a look at devise even thought it doesn't have every feature that you're asking for. But then again I doubt there's something out there doing all that.
