How to load a session by userid using node.js/express/passport/redis?

Question

I have an application which uses redis as session storage, passport for authentication, everything on top of express.

When a user logs in, the object stored in cache has a structure similar to this one:

{
     cookie : {cookie info, expiration, etc},
     passport : { user : 'userid' }
}

My question is: is there a simple way to load that session (or session id) inside the node.js app, by providing only the 'userid' field? (e.g. loadSession(userid), where loadSession returns the session id or the session itself).

A native Passport/Express/Connect-Redis alternative is preferred.

My intention is to invalidate a certain session in a given moment, without requiring the user to make an HTTP request to my app, i.e. without req.session.

Thanks in advance.

As mentioned in the comments, if the userid is all you have, you'll need to add node-redis module and search for the record with that userid — it can't be done with connect-redis alone as that module is ONLY designed for session handling.
