There is a table missing named 'users_attributes', that's why the sql query is failing.

`CREATE TABLE IF NOT EXISTS `users_attributes` (
  `user_id` int(11) NOT NULL,
  `name` varchar(80) NOT NULL,
  `value` longtext NOT NULL,
  PRIMARY KEY (`user_id`,`name`),
  KEY `user_id` (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;`

After the refactoring to Doctine 2, the users module stores the attributes to a separate table. It's not using 'objectdata_attributes' anymore.
