MaxQueryDuration no es cumplido en Samba AD DC LDAP

It was discovered that Samba did not handle MaxQueryDuration when being used in AD DC configurations, contrary to expectations. This issue only affected Ubuntu 20.04 LTS. Luke Howard discovered that Samba incorrectly handled certain restrictions associated with changing passwords. A remote attacker being requested to change passwords could possibly use this issue to escalate privileges.
