I've copied an on-premise SQL database to Azure SQL for testing, using the Azure online migration process, which is done and the database is in ready to cutover mode..
From a local Windows 10 machine using ODBC driver 17, I can set up an ODBC connection to the Azure SQL database using Active Directory Integrated security and it works fine.
From the same machine, SSMS 17 connects to the Azure SQL database fine.
However when I try the same ODBC connection from an Azure VM (Server 2016, joined to the local domain via VPN) I cannot get it to authenticate even with the same domain user. On the VM, I've tried ODBC driver 13.1 and 17.2. Here is the error message I get:
"Microsoft ODBC Driver for SQL Server Version 13.00.4414
Running connectivity tests...
[Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Failed to authenticate the user '<user>' in Active Directory (Authentication option is 'ActiveDirectoryIntegrated').
Error code 0xCAA9001F; state 10
Integrated Windows authentication supported only in federation flow.
I'm not sure why this would be any different for an Azure VM than a local machine--both are domain joined.
-Azure AD Connect is synchronizing users to Azure.
-I have the firewall open on the Azure SQL database server to allow both local subnet and the Azure vNet the VM is on.
-I have the ADAL for SQL Server and the Microsoft Online Services Sign-in Assistant both installed on the VM.
Thanks for any help.
