We do not put passwords in the attributes/default.rb file any more... I would put this here instead:

```ruby
default["cinder"]["netapp"]["df_password"] = nil
```

and then in recipes/volume.rb, do this:

```ruby
df_pass = user_password "cinder_netapp_user"
```

We would then add a password to our user_passwords encrypted data bag for cinder_netapp_user.
