I had the same problem and couldn't find this anywhere, except in the source code for databricks-cli at PowerShell:https://www.powershellgallery.com/packages/DatabricksPS/1.11.0.8/Content/Public%5CWorkspaceConfig.ps1Hope this helps someone else too.
Are you sure what you're talking about? There is no Terraform Resource for Databricks SSO Config at any workspace or account level. Could you provide more information about this?
