This provider manages the entire MCXSettings attribute available
to some directory services nodes. This management is 'all or nothing'
in that discrete application domain key value pairs are not managed
by this provider.
It is recommended to use WorkGroup Manager to configure Users, Groups,
Computers, or ComputerLists, then use 'ralsh mcx' to generate a puppet
manifest from the resulting configuration.
