I have two aws accounts and I could establish a peering of two VPCs belonging to each account. Also, I was able to launch an EC2 instance one account joining to the AD domain on the other account. The problem is I can't find a way to do the same for RDS-SQL Server, I was trying to do it from AWS console.

This what I have configured on both accounts:

AWS Account1

  • VPC1 - 172.32.0.0/16
  • ADS1 - Active Directory Service is configured in this account

AWS Account2

  • VPC2 172.33.0.0/16 - VPC2 is peered to VPC1
  • EC2 launched and join ADS1
  • RDS-SQL launched, but could not find a way to join ADS1

Please advise,

This mode is not supported directly.

See:

Using Windows Authentication with a Microsoft SQL Server DB Instance

Specifically:

Windows Authentication is only supported for SQL Server DB instances in a VPC, and the DB instance must be in the same VPC as the directory.

However you could deploy a second AD instance into the same VPC as the RDS instance and establish a trust relationship at the AD level.

See:

When to Create a Trust Relationship
