Dopo l'installazione delle patch di sicurezza di .NET per risolvere CVE-2018-8421, il crawler di SharePoint potrebbe avere esito negativo
SI APPLICA A:
2013 2016 2019 Subscription Edition 
SharePoint in Microsoft 365
Sintomi:
Dopo aver applicato gli aggiornamenti di settembre 2018 per .NET 4.6 o versioni successive, la ricerca per indicizzazione avrà esito negativo e verranno visualizzate voci simili:

Causa:
La sezione di configurazione per SqlColumnEncryptionEnclaveProviders non è definita, ma è richiesta da .NET Sql Client.
Soluzione 1:
Creare un file di configurazione per mssdmn.exe se non esiste già (per impostazione predefinita non esiste). Verificare che il contenuto del file di configurazione sia il seguente:
Contenuto di mssdmn.exe.config:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<configSections>
<section name="SqlColumnEncryptionEnclaveProviders"
type="System.Data.SqlClient.SqlColumnEncryptionEnclaveProviderConfigurationSection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</configSections>
</configuration>
In genere il file deve trovarsi qui:
SharePoint 2013: C:\Programmi\Microsoft Office Servers\15.0\bin\mssdmn.exe.config
SP 2016 e SP 2019: C:\Programmi\Microsoft Office Servers\16.0\bin\mssdmn.exe.config
Soluzione 2:
La soluzione 1 può risolvere il problema per la ricerca, ma è possibile che vengano comunque visualizzati i problemi relativi ad altri componenti. Se si riscontrano ancora problemi con altri componenti, è possibile modificare machine.config per includere la modifica.
Lo script seguente apporta automaticamente le modifiche. È necessario eseguire questa operazione in tutti i server che presentano il problema.
