def set_password(name, users, password, encrypted=True, path=None):
    '''
    .. versionchanged:: 2015.5.0
        Function renamed from ``set_pass`` to ``set_password``. Additionally,
        this function now supports (and defaults to using) a password hash
        instead of a plaintext password.

    Set the password of one or more system users inside containers


    users
        Comma-separated list (or python list) of users to change password

    password
        Password to set for the specified user(s)

    encrypted : True
        If true, ``password`` must be a password hash. Set to ``False`` to set
        a plaintext password (not recommended).

        .. versionadded:: 2015.5.0

    path
        path to the container parent directory
        default: /var/lib/lxc (system)

        .. versionadded:: 2015.8.0

    CLI Example:

    .. code-block:: bash

        salt '*' lxc.set_pass container-name root '$6$uJ2uAyLU$KoI67t8As/0fXtJOPcHKGXmUpcoYUcVR2K6x93walnShTCQvjRwq25yIkiCBOqgbfdKQSFnAo28/ek6716vEV1'
        salt '*' lxc.set_pass container-name root foo encrypted=False
