Windows DACL
============

This salt utility contains objects and functions for setting permissions to
objects in Windows. You can use the built in functions or access the objects
directly to create your own custom functionality. There are two objects, Flags
and Dacl.

If you need access only to flags, use the Flags object.

.. code-block:: python

    import salt.utils.win_dacl
    flags = salt.utils.win_dacl.Flags()
    flag_full_control = flags.ace_perms['file']['basic']['full_control']

The Dacl object inherits Flags. To use the Dacl object:

.. code-block:: python

    import salt.utils.win_dacl
    dacl = salt.utils.win_dacl.Dacl(obj_type='file')
    dacl.add_ace('Administrators', 'grant', 'full_control')
    dacl.save('C:\\temp')

Object types are used by setting the `obj_type` parameter to a valid Windows
object. Valid object types are as follows:

- file
- service
- printer
- registry
- registry32 (for WOW64)
- share

Each object type has its own set up permissions and 'applies to' properties as
follows. At this time only basic permissions are used for setting. Advanced
permissions are listed for displaying the permissions of an object that don't
match the basic permissions, ie. Special permissions. These should match the
permissions you see when you look at the security for an object.

Only the registry and file object types have 'applies to' properties. These
should match what you see when you look at the properties for an object.

    **File types:**

        - this_folder_only: Applies only to this object
        - this_folder_subfolders_files (default): Applies to this object
          and all sub containers and objects
        - this_folder_subfolders: Applies to this object and all sub
          containers, no files
        - this_folder_files: Applies to this object and all file
          objects, no containers
        - subfolders_files: Applies to all containers and objects
          beneath this object
        - subfolders_only: Applies to all containers beneath this object
        - files_only: Applies to all file objects beneath this object

    .. NOTE::

        'applies to' properties can only be modified on directories. Files
        will always be ``this_folder_only``.

    **Registry types:**

        - this_key_only: Applies only to this key
        - this_key_subkeys: Applies to this key and all subkeys
        - subkeys_only: Applies to all subkeys beneath this object

        reset (bool):
            ``True`` will clear the DACL and set only the permissions defined

        test_mode (bool):
            ``True`` will only return the changes that would be made. ``False``
            will make the changes as well as return the changes that would be

            ie:

            .. code-block:: yaml

                {'user': {'perms': ['read_attributes', 'read_ea'], 'applies_to': 'this_folder'}}

            To see a list of available attributes and applies to settings see
            the documentation for salt.utils.win_dacl.

            A value of ``None`` will make no changes to the ``grant`` portion of
            the DACL. Default is ``None``.

        deny_perms (dict):
            A dictionary containing the user/group and permissions to deny along
            with the ``applies_to`` setting. Use the same format used for the
            ``grant_perms`` parameter. Remember, deny permissions supersede
            grant permissions.

            A value of ``None`` will make no changes to the ``deny`` portion of
            the DACL. Default is ``None``.

        inheritance (bool):
            If ``True`` the object will inherit permissions from the parent, if
            ``False``, inheritance will be disabled. Inheritance setting will
            not apply to parent directories if they must be created. Default is
            ``False``.

        reset (bool):
            If ``True`` the existing DCL will be cleared and replaced with the
            settings defined in this function. If ``False``, new entries will be
            appended to the existing DACL. Default is ``False``.

    Returns:
        bool: True if successful

    Raises:
        CommandExecutionError: If unsuccessful

    Usage:
