<a name="User.SQLServer.ActiveDirectoryWindowsAuth"></a>

You can join an RDS for SQL Server DB instance to a Microsoft Active Directory (AD) domain. Your AD domain can be hosted on AWS Managed AD within AWS, or on a self-managed AD in a location of your choice, including your corporate data centers, on AWS EC2, or with other cloud providers.

You can authenticate domain users using NTLM authentication and Kerberos authentication with self-managed Active Directory and AWS Managed Microsoft AD.

In the following sections, you can find information about working with self-managed Active Directory and AWS Managed Active Directory for Microsoft SQL Server on Amazon RDS.
