    filters was insufficient and an attacker may be able to obtain confidential BitLocker recovery keys from a
    Samba AD DC. (CVE-2023-0614)

  - The Samba AD DC administration tool, when operating against a remote LDAP server, will by default send new

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
