Can't mass-assign protected attributes: password, password_confirmation

Hey
I am getting this error when i try to load the seeds.db file
moreover, adding a user from rails console gives the same error.
i am in chapter 6
this are the initial lines in my user.rb file - 

``` ruby
require 'digest'
class User < ActiveRecord::Base
   attr_accessible :email
   attr_accessor :password
```

rest is as is in the tutorial.
thanks.
