Manage the password database on BSD systems

minion, and it is using a different module (or gives an error similar to
*'shadow.info' is not available*), see :ref:`here

Set the password for a named user. The password must be a properly defined
hash. The password hash can be generated with this command:
``python -c "import crypt; print crypt.crypt('password', ciphersalt)"``
.. note::
When constructing the ``ciphersalt`` string, you must escape any dollar
signs, to avoid them being interpolated by the shell.
``'password'`` is, of course, the password for which you want to generate
a hash.
``ciphersalt`` is a combination of a cipher identifier, an optional number
of rounds, and the cryptographic salt. The arrangement and format of these
fields depends on the cipher and which flavor of BSD you are using. For
more information on this, see the manpage for ``crpyt(3)``. On NetBSD,
additional information is available in ``passwd.conf(5)``.
It is important to make sure that a supported cipher is used.
CLI Example:
.. code-block:: bash
salt '*' shadow.set_password someuser '$1$UYCIxa628.9qXjpQCjM4a..'
