Keystone Security Compliance Configuration

You can configure custom password rules for keystone security compliance.

  1. Use the following parameters to set the rules for keystone security compliance.

    system service-parameter-add identity security_compliance unique_last_password_count
    system service-parameter-add identity security_compliance password_regex
    system service-parameter-add identity security_compliance password_regex_description
  2. In order for the changes to take effect, apply the new configuration with the command:

    system service-parameter-apply identity

    For security reasons these parameters are validated:

    • unique_last_password_count must be an integer equal or greater than zero.
    • password_regex must be a valid regex conforming to the Python Regular Expression (RE) syntax: https://docs.python.org/3/library/re.html.
    • password_regex_description must be a non empty string.

    Note

    The password_regex_description will be used by keystone as part of the error message when the user tries a password that does not conform to the rules. Make sure to have an explanatory description.

    For example:

    [sysadmin@controller-0 ~(keystone_admin)]$ system service-parameter-add identity security_compliance unique_last_password_count=7

    Applying platform service parameters
  3. The system service-parameter-apply command will apply the configuration to /etc/keystone/keystone.conf and restart the keystone service.

    To see the exact moment keystone is restarted, check the sm-customer.log:

  4. Search for keystone.conf to see the new rules being persisted.

    [sysadmin@controller-1 ~(keystone_admin)]$ sudo grep "unique_last_password_count\|password_regex" /etc/keystone/keystone.conf
    #unique_last_password_count = 0
    unique_last_password_count = 7
    #password_regex = <None>
    password_regex = ^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*()<>{}+=_\\\[\]\-?|~`,.;:]).{20,}$
    #password_regex_description = <None>
    password_regex_description = 20 characters minimum, must have numbers and special characters
  5. After that, the new rules are already in place, and they can be used.

    [sysadmin@controller-1 ~(keystone_admin)]$ openstack user password set
    Current Password:
    New Password:
    Repeat New Password:
