Hi @Harsha ,
As far as I know, AAD account is only used to connect to Azure SQL Database.
If you want to connect to SQL DB on pre in SSIS package, you could only use SQL Server authentication or Windows authentication like shown below.
Could you please have a check of the issue so that we could do more analysis.
Hi @Harsha ,
You can not pass other user account for the Windows Authentication.
If you are concerned about security, you may use ProtectionLevel which is an SSIS package property that is used to specify how sensitive information is saved within the package and also whether to encrypt the package or the sensitive portions of the package.
