Thanks euromak.

I like the solution to check if it is empty but ... How do I distinguish 
between "add action" and "edit action"?
If I add a new user the password should be mandatory.
If I edit the user then the password is blank if not modified.

Another thing .... How can see the current value of the field in database? 
For example

function beforeSave(){
     if(empty($this->data[$this->alias]['password']))
            $this->data[$this->alias]['password'] = currentPassword;  // 
hash password stored in data base
     else
            $this->data[$this->alias]['password'] = 
AuthComponent::password($this->data[$this->alias]['password']);

return true;
}

Thanks!
