Manage Windows Local Group Policy
=================================

.. versionadded:: 2016.11.0

This state module allows you to configure local Group Policy on Windows. You
can ensure the setting of a single policy or multiple policies in one pass.

Single policies must specify the policy name, the setting, and the policy class
(Machine/User/Both). Here are some examples for setting a single policy setting.

Example single policy configuration:

.. code-block:: yaml

    Ensure Account Lockout Duration:
      lgpo.set:
        - name: Account lockout duration
        - setting: 90
        - policy_class: Machine

Example using abbreviated form:

.. code-block:: yaml

    Account lockout duration:
      lgpo.set:
        - setting: 120
        - policy_class: Machine

It is also possible to set multiple policies in a single state. This is done by
setting the settings under either `computer_policy` or `user_policy`. Here are
some examples for setting multiple policy settings in a single state.

Multiple policy configuration

.. code-block:: yaml

    Company Local Group Policy:
        lgpo.set:
            - computer_policy:

                  - Guest
                Account lockout duration: 120
                Account lockout threshold: 10
                Reset account lockout counter after: 120

        - cumulative_rights_assignments: True

    Some policy settings can't be set on their own an require that other policy
    settings are set at the same time. It can be difficult to figure out what
    additional settings need to be applied. The easiest way to do this is to
    modify the setting manually using the Group Policy Editor (`gpedit.msc`) on
    the machine. Then `get` the policy settings configured on that machine. Use
    the following command:

    .. code-block:: bash

        salt-call --local lgpo.get machine

    For example, if I want to set the Windows Update settings for a Windows
    Server 2016 machine I would go into the Group Policy Editor (`gpedit.msc`)
    and configure the group policy. That policy can be found at: Computer
    Configuration -> Administrative Templates -> Windows Components -> Windows
    Update -> Configure Automatic Updates. You have the option to "Enable" the
    policy and set some configuration options. In this example, just click
    "Enable" and accept the default configuration options. Click "OK" to apply
    the setting.

    Now run the `get` command as shown above. You will find the following in
    the minion return:

    .. code-block:: bash

        Windows Components\Windows Update\Configure Automatic Updates:
            ----------
            Configure automatic updating:
                3 - Auto download and notify for install
            Install during automatic maintenance:
                False
            Install updates for other Microsoft products:
                False
            Scheduled install day:
                0 - Every day
            Scheduled install time:
                03:00

    This shows you that to enable the "Configure Automatic Updates" policy you
    also have to configure the following settings:

    - Configure automatic updating
    - Install during automatic maintenance
    - Install updates for other Microsoft products
    - Scheduled install day
    - Scheduled install time

    So, if you were writing a state for the above policy, it would look like
    this:

    .. code-block:: bash

        configure_windows_update_settings:
          lgpo.set:
            - computer_policy:
                Configure Automatic Updates:
                  Configure automatic updating: 3 - Auto download and notify for install
                  Install during automatic maintenance: False
                  Install updates for other Microsoft products: False
                  Scheduled install day: 0 - Every day
                  Scheduled install time: 03:00

    .. note::

        It is important that you put names of policies and settings exactly as
        they are displayed in the return. That includes capitalization and
        punctuation such as periods, dashes, etc. This rule applies to both
        the setting name and the setting value.

    .. warning::

        From time to time Microsoft updates the Administrative templates on the
        machine. This can cause the policy name to change or the list of
        settings that must be applied at the same time. These settings often
        change between versions of Windows as well. For example, Windows Server
        2019 allows you to also specify a specific week of the month to apply
        the update.

    Another thing note is the long policy name returned by the `get` function:

    .. code-block:: bash

        Windows Components\Windows Update\Configure Automatic Updates:

    When we wrote the state for this policy we only used the final portion of
    the policy name, `Configure Automatic Updates`. This usually works fine, but
    if you are having problems, you may try the long policy name.

    When writing the long name in a state file either wrap the name in single
    quotes to make yaml see it as raw data, or escape the back slashes.

    .. code-block:: bash

        'Windows Components\Windows Update\Configure Automatic Updates:'

        or

        Windows Components\\Windows Update\\Configure Automatic Updates:

    Helper function that makes sure all items in the dictionary are unicode for
    comparing the existing state with the desired state. This function is only
    needed for Python 2 and can be removed once we've migrated to Python 3.

    The data returned by the current settings sometimes has a mix of unicode and
    string values (these don't matter in Py3). This causes the comparison to
    say it's not in the correct state even though it is. They basically compares
    apples to apples, etc.

    Also, in Python 2, the utf-16 encoded strings remain utf-16 encoded (each
    character separated by `/x00`) In Python 3 it returns a utf-8 string. This
    will just remove all the null bytes (`/x00`), again comparing apples to
    apples.

    Ensure the specified policy is set.

    .. warning::
        The ``setting`` argument cannot be used in conjunction with the
        ``computer_policy`` or ``user_policy`` arguments

    Args:
        name (str): The name of a single policy to configure

        setting (str, dict, list):
            The configuration setting for the single named policy. If this
            argument is used the ``computer_policy`` / ``user_policy`` arguments
            will be ignored

        policy_class (str):
            The policy class of the single named policy to configure. This can
            ``machine``, ``user``, or ``both``

        computer_policy (dict):
            A dictionary of containing the policy name and key/value pairs of a
            set of computer policies to configure. If this argument is used, the
            ``name`` / ``policy_class`` arguments will be ignored

        user_policy (dict):
            A dictionary of containing the policy name and key/value pairs of a
            set of user policies to configure. If this argument is used, the
            ``name`` / ``policy_class`` arguments will be ignored

        cumulative_rights_assignments (bool):
            If user rights assignments are being configured, determines if any
            user right assignment policies specified will be cumulative or
            explicit

        adml_language (str):
            The adml language to use for AMDX policy data/display conversions.
            Default is ``en-US``

        refresh_cache (bool):
            Clear the cached policy definitions before applying the state. This
            is useful when the underlying policy files (ADMX/ADML) have been
            added/modified in the same state. This will allow those new policies
            to be picked up. This adds time to the state run when applied to
            multiple states within the same run. Therefore, it is best to only
            apply this to the first policy that is applied. For individual runs
            this will have no effect. Default is ``False``
