Active directory authentication in Sitecore 9.3 for on-premise AD

We are upgrading our solution from Sitecore 9.0.2 to Siteore 9.3. We are using Active directory module for authenticating the user. Since AD module is not supported by Sitecore 9.1.0 or later, Can someone please help me with some good articles which i can use to integrate On Premise Ad with Sitecore Idenityserver.

Appreciate your help.
