.. rubric:: Check Current Password Expiry Settings
|
|
|
|
Before making any changes, you may want to check the current password expiry
|
|
settings for the user. You can do this by running the :command:`chage -l
|
|
<username>` command, replacing ``<username>`` with the name of the user whose
|
|
password expiry settings you want to view.
|
|
|
|
.. code-block:: none
|
|
|
|
sudo chage -l <username>
|
|
|
|
.. rubric:: Change Password Expiry Settings
|
|
|
|
To change the password expiry period of Linux accounts, run the :command:`chage`
|
|
command, as bellow:
|
|
|
|
.. code-block:: none
|
|
|
|
[sysadmin@controller-0 ~(keystone_admin)]$ sudo chage -M <days_to_expiry> <username>
|
|
|
|
For example, to set the maximum number of days before the password must be
|
|
changed to 60 days for a user named ``sysadmin``, you can use the following
|
|
command:
|
|
|
|
.. code-block:: none
|
|
|
|
[sysadmin@controller-0 ~(keystone_admin)]$ sudo chage -M 60 sysadmin
|
|
|
|
|
|
Verify Changes
|
|
--------------
|
|
|
|
After making the changes, verify that the new password expiry settings have
|
|
been applied by running the :command:`chage -l <username>` command again.
|
|
|
|
.. code-block:: none
|
|
|
|
chage -l <username>
|
|
|
|
For the example above of user ``sysadmin`` and expiry period of 60 days, the
|
|
output of ``chage -l <username>`` should be as follows:
|
|
|
|
.. code-block:: none
|
|
|
|
[sysadmin@controller-0 ~(keystone_admin)]$ chage -l sysadmin
|
