Failed to get group from OpenLDAP

I am using OpenLDAP to evaluate Mendix, installed ldap module with Studio Pro.  At LDAP server side                 I have created Both groupOfNames & groupOfUniqueNames, added a user into both group.   At mendix LDAP module side               If ‘Sychronize by path’ I can get users from LDAP, but group doesn’t show up, therefore I failed to map imported user to Mendix roles.                If ‘Sychornize’ by group, Nothing is imported                I didn’t see any errors from console  My  questions are, why failed to import groups from OPENLDAP?

It seems OpenLDAP doesn’t work with LDAP Synchronization Module.
