Windows Authentication for Azure AD principals for SQL Managed Instance is now Generally Available

luistorres, that patch seems designed to resolve authentication errors; I am not nearly that far into the process. I can't figure out how to grant a local service account permission to delegate kerberos tickets to the Azure service principal. It's not that it doesn't work, it's that the Azure SP doesn't exist in my local AD.

GarryBargsleyI didn't encounter that specific error, but I'd guess that your Windows login is failing to match against a login in SQL Server.  Assuming that you're trying to connect as a member of the https://learn.microsoft.com/en-us/azure/azure-sql/database/authentication-aad-configure?view=azuresql&tabs=azure-powershell#provision-azure-ad-admin-sql-managed-instance group/user, I'd try removing and re-adding the admin group/user from your Managed Instance.
