Description:

def get(path, objectType, user=None):
    '''
    Get the ACL of an object. Will filter by user if one is provided.

    Args:
        path: The path to the object
        objectType: The type of object (FILE, DIRECTORY, REGISTRY)
        user: A user name to filter by

    Returns (dict): A dictionary containing the ACL

    CLI Example:

    .. code-block:: bash

        salt 'minion-id' win_dacl.get c:\temp directory
    '''
    ret = {'Path': path,
           'ACLs': []}

    sidRet = _getUserSid(user)

    if path and objectType:
        dc = daclConstants()
        objectTypeBit = dc.getObjectTypeBit(objectType)
        path = dc.processPath(path, objectTypeBit)
        tdacl = _get_dacl(path, objectTypeBit)
        if tdacl:
            for counter in range(0, tdacl.GetAceCount()):
                tAce = tdacl.GetAce(counter)
                if not sidRet['sid'] or (tAce[2] == sidRet['sid']):
                    ret['ACLs'].append(_ace_to_text(tAce, objectTypeBit))
    return ret
