Amazon RDS for SQL Server now supports Kerberos authentication with self-managed Active Directory

Amazon Relational Database Service (Amazon RDS) for SQL Server now supports Kerberos authentication with self-managed Microsoft Active Directory (AD). With this launch, your applications can use Kerberos authentication to connect to your Amazon RDS for SQL Server instances joined to self-managed AD.

Previously, customers integrating Amazon RDS for SQL Server with Microsoft Active Directory had to use AWS Managed AD for Kerberos authentication. Now, customers can setup Kerberos authentication when integrating Amazon RDS for SQL Server with Microsoft AD without having to use AWS Managed AD. For customers that are migrating on-premises SQL Server databases to Amazon RDS for SQL Server, this feature simplifies migration by removing the requirement to adopt Amazon Managed AD to use Kerberos authentication. Customers who use Amazon RDS for SQL Server with AWS Managed AD can continue to use their existing integration.

To join your Amazon RDS for SQL Server instance to a self-managed AD and setup Kerberos authentication, refer to the Amazon RDS for SQL Server User Guide. This feature is available in all AWS Commercial and AWS GovCloud (US) Regions.
