Enhancing Security and Integration: Amazon RDS for SQL Server Now Supports Kerberos Authentication with Self-Managed Active Directory
Amazon Web Services (AWS) is pleased to announce a significant enhancement to Amazon Relational Database Service (RDS) for SQL Server: the introduction of support for Kerberos authentication when integrated with self-managed Microsoft Active Directory (AD). This update, published on August 19, 2025, represents a vital step forward in providing customers with more robust security options and seamless integration capabilities for their database workloads running on RDS.
For organizations that have invested in and continue to manage their own on-premises or AWS-hosted Active Directory environments, this new feature offers a powerful way to leverage existing identity management infrastructure for their Amazon RDS for SQL Server instances. Kerberos, a widely adopted network authentication protocol, is known for its strong security features and its ability to provide single sign-on (SSO) capabilities across various network resources.
What This Means for You:
The integration of Kerberos authentication with self-managed Active Directory allows you to:
- Strengthen Security Posture: By utilizing Kerberos, you can enforce a centralized and highly secure authentication mechanism for your SQL Server databases. This helps to reduce the risk of unauthorized access and ensures that only authenticated and authorized users can connect to your database instances.
- Streamline User Management: Leverage your existing Active Directory user accounts and groups. This eliminates the need to manage separate sets of credentials for your database users, simplifying administration and reducing the potential for credential sprawl.
- Enable Single Sign-On (SSO): For users already authenticated within your Active Directory domain, Kerberos authentication can enable a smoother user experience by providing single sign-on access to your Amazon RDS for SQL Server databases. This means fewer logins and improved productivity.
- Meet Compliance Requirements: Many regulatory frameworks and industry standards mandate strong authentication and access control mechanisms. This new feature can help your organization meet these compliance obligations by providing a proven and widely recognized authentication protocol.
- Facilitate Hybrid Cloud Strategies: For businesses operating in a hybrid cloud model, this integration is particularly valuable. It allows for consistent security policies and user management across both on-premises and cloud environments, fostering a unified approach to identity and access.
How it Works:
With this new capability, you can now configure your Amazon RDS for SQL Server instances to authenticate users directly against your self-managed Active Directory domain. This involves establishing a trust relationship between your RDS environment and your AD domain, allowing RDS to leverage Kerberos tickets for user authentication. AWS has designed this integration to be as straightforward as possible, providing comprehensive documentation and guidance to assist you in setting up and configuring this advanced authentication method.
A Commitment to Enhanced Security and Flexibility:
AWS is continuously committed to providing customers with the tools and services they need to build and manage secure, scalable, and highly available applications. The introduction of Kerberos authentication for Amazon RDS for SQL Server with self-managed Active Directory is a testament to this commitment, offering enhanced security, improved operational efficiency, and greater flexibility for a diverse range of customer requirements.
We encourage you to explore this new feature and discover how it can benefit your organization’s database security and integration strategies. For detailed instructions on how to set up and configure Kerberos authentication, please refer to the official Amazon RDS for SQL Server documentation.
