I know that Facebook use their own OpenID-like system called "Facebook connect", which you can use to authenticate users on your site, among other features.

In my case I have multiple Ruby on Rails applications:

users.example.com
profiles.example.com
photos.example.com
...

I would like to use 'users.example.com' as a web service that allows users to authenticate to all my other applications the same way as works "Facebook connect" or OpenID. In few words, 'users.example.com' must works as a "OpenID-like system" for my applications in 'example.com'.

Can anyone give me tips and links to some useful resources?

P.S.: since I am a newbie in this matter, I do not know if I'm saying things that make sense. So someone could help me to understand (if I am wrong) ...
