Ranger group sync authorization is not working

[#1]

We have configured group sync uisng LDAP for Ranger. Also on the OS level we have configured SSSD to sync with AD. Able to see the AD groups in Groups tab of Ranger. Also on running id <username>, we are able to see the groups the user is part of. But the output of hdfs groups is null. ALso the ranger authorization using AD groups is not happening
