filterSocketsByUser() with multiple instances

[benjhoo]

Hi,
I'm using passport.socketio to manage my users authentication with websocket and it works perfectly.

Also, I'm using the filterSocketsByUser() function in order to filter the sockets by user id.
It works well if I get one instance of my app launched. But, with loadbalancing, the function only returns sockets depending on the instance the users are connected to.

Is there a way to get back all the sockets of a user connected through multiple instances ?

(io.emit is well received by all clients, regardless of the instance the user is connected to)

Thanks
