Amazon Redshift customers can now use the identities in their identity provider (IdP), such as Microsoft Entra ID, Okta, Ping, OneLogin, etc., to access Amazon Redshift in a single sign-on experience from Amazon QuickSight or Amazon Redshift Query Editor. Administrators can manage fine grained access to data in Redshift using the users and groups in the organization IdP, and can audit user access in AWS CloudTrail.
