The ``ssh_pwauth`` config key determines whether or not sshd will be configured to accept password authentication. The ``chpasswd`` config key accepts a dictionary containing either or both of ``users`` and ``expire``. The ``users`` key is used to assign a password to a corresponding pre-existing user. The ``expire`` key is used to set whether to expire all user passwords specified by this module, such that a password will need to be reset on the user's next login. .. note:: Prior to cloud-init 22.3, the ``expire`` key only applies to plain text (including ``RANDOM``) passwords. Post 22.3, the ``expire`` key applies to both plain text and hashed passwords. ``password`` config key is used to set the default user's password. It is ignored if the ``chpasswd`` ``users`` is used. Note: the ``list`` keyword is deprecated in favor of ``users``. �cc_set_passwordsz Set Passwordsz7Set user passwords and enable/disable SSH password authz� # Set a default password that would need to be changed # at first login ssh_pwauth: true password: password1 aU # Disable ssh password authentication # Don't require users to change their passwords on next login # Set the password for user1 to be 'password1' (OS does hashing) # Set the password for user2 to a pre-hashed password # Set the password for user3 to be a randomly generated password, # which will be written to the system console ssh_pwauth: false chpasswd: expire: false users: - name: user1 password: password1 type: text - name: user2 password: $6$rounds=4096$5DJ8a9WMTEzIo5J4$Yms6imfeBvf3Yfu84mQBerh18l7OR1Wm1BJXZqFSpJ6BVas0AYJqIjP7czkOaAZHZi1kxQ5Y1IhgWN8K9NgxR1 - name: user3 type: RANDOM )�id�name�title� description�distros� frequency�examples�activate_by_schema_keys�meta� c C s g | ]}|d vr|�qS )�loLOI01� )�.0�xr r �C/usr/lib/python3/dist-packages/cloudinit/config/cc_set_passwords.py� <listcomp>^ s r# � users_list�pw_type�returnc s | sg S � fdd�| D �S )zDeither password or type: RANDOM is required, user is always requiredc s0 g | ]}|� d d�� kr|d |� dd�f�qS )�type�hashr �password�RANDOM)�get)r �item�r% r r" r# f s �z%get_users_by_type.<locals>.<listcomp>r )r$ r% r r- r" �get_users_by_typea s �� ��r. c C sR z| � d|� t�d� W d S tjy( } z t�d|� W Y d }~d S d }~ww )N�restartzRestarted the SSH daemon.zm'ssh_pwauth' configuration may not be applied.
