I am facing an issue while running ranger user sync. It's able to sync groups but not users. I am not getting any errors also.
Not sure if this older solution will help but it's worth a look.
Hi, Are you able to see the users in the usersync logs ? can you please share the usersync logs from ranger and also some users which are not synced to check logs.
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.
