Earlier this week I was attempting to create an Entra ID Kerberos server object, and I kept running into these errors: Set-AzureADKerberosServer : Failed to read secrets from the domain Set-AzureADKerberosServer : Failed to connect to domain Normally these errors occur for these reasons: The Microsoft.Online.PasswordSynchronization.Rpc.dll is missing from the server, or the server is missing a .dll from the AzureADHybridAuthenticationManagement module The cloud credentials and the domain credentials are entered incorrectly.
