> *SYMPTOM*
>  With LDAP server which has hundreds of users and groups, Ranger Usersync never finishes
the initial sync or takes extremely long time, when Group Search First & Enable User
Search both are set to true.
>  The usersync.log shows similar to below repeatedly.
> {noformat}
> 19 Apr 2018 17:15:19 INFO LdapUserGroupBuilder [UnixUserSyncThread] - Updating username
for cn=xxxxx...
> {noformat}
>  
> *WORKAROUND:*
>  If deltasync (Incremental Sync) is enabled, do not see this symptom, because LdapUserGroupBuilder
calls getUsers() in the for loop, but LdapDeltaUserGroupBuilder doesn't use this method in
the loop in updateSink().
