Although I have not tried to use any OpenID provider software in Ruby or Rails for several years, I think you should give masquerade another try. It seems to me that at least there is a bit of activity, and at least they seem to have already made the transition to Rails 3.xx (which is already bigger than some of the most popular Rails-based free software projects, which I can offer. you have Redmine ).
In addition, the main author of the masquerade seems to be currently working on a successor project to masq , which appears to be intended as an openID provider mount engine. After that, you can easily improve any existing Rails> = 3.1.0 application to act as an OpenID provider. I have no idea how stable this project is, though.
