Utilizzo CreateCertificateAuthority per supportare Active Directory

Il seguente esempio di Java mostra come utilizzare l'CreateCerticateAuthorityoperazione per creare una CA che può essere installata nell'archivio Enterprise NTAuth di Microsoft Active Directory (AD).

L'operazione crea un'autorità di certificazione (CA) principale privata utilizzando identificatori di oggetti (OID) personalizzati. Per ulteriori informazioni e un AWS CLI esempio di operazione equivalente, vedere Creare una CA per l'accesso ad Active Directory.

Se eseguita correttamente, questa funzione restituisce l'Amazon Resource Name (ARN) della CA.
