In MIT krb5, when kadmind is configured to use LDAP for the KDC
database, an authenticated remote attacker can cause a NULL

password policy for a principal. The attacker needs to be
authenticated as a user who has the elevated privilege for setting
password policy by adding or modifying principals (CVE-2014-5353)."
