I have used 'posixGroup' objectClass for creating groups, and 'posixAccount' object class for creating users, which uses 'gidNumber' property to associate to a specific group (created by posixGroup).

I have to sync LDAP users/groups in Apache Ranger, that uses 'groupOfNames' object class and 'member/memberof' property in user object. But in 'groupOfNames' objectClass we have to add members at the time of creation of group.

Is there any way that we can add members to already created groups later on?
