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:
   The password does not match the requirements: 20 characters minimum, must have numbers and special characters. (HTTP 400) (Request-ID: req-3aa0f2f9-eef8-4f28-8e3c-ae4a7eaf1d29)
