You will need to use an External Method to be able to call _getPassword on 
a user object. External Methods are allowed to call methods starting with 
an underscore.

Don't try and read the __ variable, because that is not part of the User 
object API. UserDB for example uses _getPassword to return the password 
stored in the backend database.
