Hi,

You could be a little more accurate with your description, but I think the problem is probably a typo in the ` __name__ ` of your model : it should be `res.user` rather than `res.User`

I think that the module `authentication_sms` is not from the same series as the server. The server is 5.0 so all the modules should be from series 5.0.
