CVE-2016-7030
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedFreeIPA uses a default password policy that locks an account after 5 unsuccessful authentication attempts, which allows remote attackers to cause a denial of service by locking out the account in which system services run on.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify FreeIPA installation and versionRun command: ipa --version or rpm -q freeipa-server to determine the installed FreeIPA versionAffected if FreeIPA version is exactly 4.6.0
-
Retrieve the default password policyExecute: ipa pwpolicy-show (or ldapsearch for cn=Password Policy,cn=accounts,cn=ipa,cn=etc) to view the default password policy settingsAffected if The policy shows a maxfailedlogin or similar attribute set to 5 failed attempts
-
Check which accounts use the default policyQuery which user accounts (especially service accounts) are assigned to the default password policy container or groupAffected if Service accounts or system processes use the default policy and can be locked out after 5 failed attempts
-
Verify account lockout is not disabled for service accountsReview whether any service accounts have been exempted from the default lockout policy or have a custom policy appliedAffected if Service accounts rely on the default policy with the 5-attempt threshold and have no exemption
You are affected if FreeIPA version 4.6.0 is installed and service accounts use the default password policy with a 5-failed-attempt lockout threshold.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataModify the default password policy to increase the failed authentication threshold or create a separate lockout policy for service accounts that exempts them from account lockout.
