Groups not visible in Ranger web UI

Good evening everyone, I have a problem on ranger, the users have access to the databases and everything works, but on the ranger web ui if I try to search for users belonging to the groups the following screen is shown. Even if checking in Unix the group contains several users:

I saw that there is a KB for the same problem after upgrade but I already upgraded to 7.1.7sp1. Can anyone help me? Thank you

Most likely, there was a synchronization error.
Where are users with groups stored - in Active Directory?
It is advisable to provide a fragment of the log and settings related to the synchronization of users and groups in ranger-ugsync-site.xml

which version of Apache Ranger is used?

Hello,

the ranger version is 2.1.0 and there are no error logs.

the ranger-ugsync-site.xml file contains:

<?xml version="1.0" encoding="UTF-8"?>
