AWS SSO Access for Linux?

Looking to determine best method to access AWS Linux (RHEL 8) EC2 Instances via SSO. I have found this resource [here] (https://aws.amazon.com/blogs/security/configure-aws-sso-abac-for-ec2-instances-and-systems-manager-session-manager/), but it still requires the creation of local user’s in each target instance. Windows handles the incoming SSO users well via Systems Manager, but not Linux.

I can, but would like to authenticate using SSO - like you can using Windows via Systems Manage and SSO.

You can use SSO to federate into AWS, with the permission for SSO.

@Rodney Lester, yes I am using SSO to login to the subordinate AWS account console. After which, I can login to a Windows EC2 Instance using the same federated account by using the SSO option in Session Manager. Unfortunately, this option is not available for Linux.

How can I login using this federated user into the Linux EC2 Instance?

See here for how to add session manager permissions to your IAM Role: https://docs.aws.amazon.com/systems-manager/latest/userguide/getting-started-add-permissions-to-existing-profile.html
