Major Description
As part of RANGER-2986, group search is made mandatory. This is breaking an usecase to sync users and all the corresponding groups from AD/LDAP.
Previously, this could be achieved by setting ranger.usersync.group.searchenabled to false and configure ranger.usersync.ldap.user.groupnameattribute=memberof. That way, usersync used to sync the users based on the user search base and user search filter and use the "memberof" attribute of the user to sync all the groups each user belongs to.
Now, if you want to achieve the same functionality, group search base and group search filter have to be configured with appropriate filters for sync'ing the groups which might be an extra configuration overhead.
This is same for both full sync and incremental sync.
Note:- When incremental sync is enabled, it is highly recommended to enable group search and configure group search base and group search filter accordingly. (Refer to RANGER-1211 for more details)
