so, in a model file, i have following code...

&lt;?php


class Task extends AppModel {

var $name = 'Task';
var $displayField = 'projectName';

//The Associations below have been created with all possible keys, those that are not needed can be removed
var $belongsTo = array(
    'User' =&gt; array(
        'className' =&gt; 'User',
        'foreignKey' =&gt; 'user_id',
        'conditions' =&gt; '',
        'fields' =&gt; '',
        'order' =&gt; ''


etc...

Question: Local user accounts have disappeared after installing Active Directory and running dcpromo
Answer: Once a member server is promoted to a domain controller it will no longer have local accounts. When you demote the domain controller it will ask you to set a new local administrator password. However I am not sure how you would restart the active directory service if you disabled it entirely. Here is a link for reference about local accounts not being available on a domain controller. 

EDIT: like Ben said directory restore mode is your best bet with this.
