AD Starter Scan - Non-Expiring Account Password

medium Nessus Plugin ID 150483
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


Accounts with never expiring passwords


Active Directory accounts can be configured to escape global password renewal policies. Accounts set up like this can be used indefinitely without ever changing their password. User and administrator accounts should never have this attribute set.

By default, this check skips disabled accounts. To also check disabled accounts, please enable thorough tests.

Note: This plugin is part of the Active Directory Starter Scan Template and is meant to be used for preliminary analysis of AD hosts. For more information on the issues discovered by the Active Directory Starter Scan plugins, please refer to this blog post -


A password expiration policy limits the risk of an attacker guessing or cracking a password before it is changed. All the user accounts and administrator accounts must follow this policy without exception.

Service accounts can be more difficult to deal with: if a password expires and it has not been taken into account by the application developer, the service might stop functioning. A special procedure must then be written to allow for a manual password change on a regular basis.
