Configurare un'applicazione Azure per OneDrive

Per creare un'applicazione Microsoft Azure nel portale Azure, segui questi passaggi. Se utilizzi il metodo di importazione avanzata dei dati per copiare i dati di OneDrive nei tuoi account Google Workspace, hai bisogno dell'applicazione Azure per garantire un'importazione sicura dei dati. Puoi scegliere uno dei due metodi seguenti:

Utilizza uno script PowerShell per configurare una connessione automatica

Per completare questi passaggi, devi essere un amministratore con un ruolo globale o con privilegi.

Opzione 1: utilizza Azure Cloud Shell

  1. Accedi al portale Azure come amministratore.
  2. Fai clic su Cloud Shell e poi Powershell.
  3. Se ti viene richiesto, crea un account di archiviazione e accetta le impostazioni predefinite.
  4. Per creare l'applicazione, inserisci il seguente comando e poi fai clic su Invio :

    Install-Module Microsoft.Graph -Scope CurrentUser

  5. Se ti viene richiesto di installare da un repository non attendibile, inserisci Y e poi fai clic su Invio.
  6. Copia il seguente blocco di codice, incollalo in PowerShell e fai clic su Invio.

Utilizza Microsoft Azure per configurare una connessione manuale

I passaggi specifici di Microsoft potrebbero variare a seconda della versione del portale Azure e degli aggiornamenti apportati da Microsoft. Per le indicazioni più recenti sulla registrazione e l'autorizzazione delle app, consulta la documentazione di Microsoft.

Passaggio 1: registra una nuova applicazione

  1. Accedi al portale Azure come amministratore.
  2. In Servizi Azure, vai a Registrazioni app.
  3. Fai clic su Nuova registrazione e inserisci un nome per l'applicazione (ad es. App di importazione avanzata).
  4. In Tipi di account supportati, fai clic su Solo account in questa directory dell'organizzazione per creare un'applicazione a tenant singolo.
  5. Fai clic su Registra.

Passaggio 2: configura le autorizzazioni API

Scegli una delle seguenti opzioni:

Opzione 1: aggiungi manualmente le autorizzazioni

  1. A lato, nella sezione Gestisci, fai clic su Autorizzazioni API.
  2. Fai clic su Aggiungi un'autorizzazione e nella scheda API Microsoft fai clic su SharePoint.
  3. Fai clic su Autorizzazioni applicazione e nel menu a discesa Siti seleziona la casella Sites.FullControl.All.
  4. Fai clic su Aggiungi autorizzazione.
  5. Torna ad Aggiungi un'autorizzazione e seleziona Microsoft Graph.
  6. Fai clic su Autorizzazioni applicazione e concedi le seguenti autorizzazioni:
    • LicenseAssignment.Read.All
    • Application.Read.All
  7. Fai clic su Aggiungi autorizzazione.
  8. Fai clic su Concedi il consenso amministratore per la tua organizzazione per assicurarti che l'applicazione abbia l'autorità per accedere ai dati.

Opzione 2: modifica il manifest dell'applicazione

  1. Apri il manifest dell'applicazione.
  2. Vai a “resourceAccess” : [ ] e scegli un'opzione:
    • Se “resourceAccess” : [ ] ha già un valore, aggiungi una virgola e poi incolla il seguente blocco di codice.
    • Se “resourceAccess” : [ ] non ha un valore, copia e incolla il seguente blocco di codice. 
         "requiredResourceAccess": [
    {
        "resourceAppId": "00000003-0000-0000-c000-000000000000",
        "resourceAccess": [
            {
                "id": "e2f98668-2877-4f38-a2f4-8202e0717aa1",
                "type": "Role"
            },
            {
                "id": "9a5d68dd-52b0-4cc2-bd40-abcf44ac3a30",
                "type": "Role"
            }
        ]
    },
    {
        "resourceAppId": "00000003-0000-0ff1-ce00-000000000000",
        "resourceAccess": [
            {
                "id": "678536fe-1083-478a-9c59-b99265e6b0d3",
                "type": "Role"
            }
        ]
    }
]
  3. Fai clic su Concedi il consenso amministratore per la tua organizzazione.

Passaggio 3: genera il client secret

  1. A lato, in Gestisci, fai clic su Certificati e secret e poi Nuovo client secret.
  2. Inserisci una descrizione, seleziona un periodo di scadenza e fai clic su Aggiungi.
  3. Copia il valore del client secret e conservalo in un luogo sicuro. Il valore viene visualizzato una sola volta.

Passaggio 4: raccogli le credenziali dell'applicazione

Importante: conserva le credenziali dell'applicazione in un luogo sicuro. Se le credenziali trapelano, gli hacker potrebbero accedere a tutti i tuoi dati di OneDrive.

Fai clic su Panoramica e prendi nota in modo sicuro delle seguenti credenziali:

  • ID applicazione (client)
  • ID directory (tenant)
