Has anyone successfully configured Identity Server 2.0.1 (SC 9.1.1) to use Active Directory? The only official documentation and examples I have seen are with Azure AD (not regular on prem AD). I found this very good blog post (https://sitecore.derekc.net/setting-up-azure-active-directory-integration-with-sitecore-identity-server-sitecore-9-1/) but that is for Azure AD.
It seems odd to me that Sitecore would not provide out of the box support with examples for regular Active Directory. Unless I am missing something and it is simple to set up for regular AD.
