addnode and createusers plugin don't work together

[tbrandvik]

I have a cluster with three users created with the createusers plugin. When I add nodes to this cluster, everything works correctly but something appears to go wrong with the SSH setup for the user and I get a "permission denied" error when any of the users try to login to the new nodes. I've had a look at the on_add_node function in the plugin, but can't find anything that's obviously wrong.

@tbrandvik did you use the ssh key file provided for the user you were trying to login ?
