Hi,

 

Below are configuration for connecting Apache Ranger with LDAP/LDAPS. There's an important tool that will help to identify some settings in your AD AD Explorer - Windows Sysinternals | Microsoft Docs

 This configuration will sync LDAP users and link them with their LDAP groups every 12 hour, so you later from Apache Ranger you can give permission based on LDAP groups as well.

 

For connecting using LDAPS, make sure you have the proper certificates added in the same server that contains the Ranger's UserSync service.
