We want to have consistent naming for this group, we already have 'Trust Admins' so we should use the same style for this group and use 'Default SMB Group'.
Also we want to force this group to have no members, we can achieve that by simply not adding the groupofnames/ipausergroup/nestedgroup objectclasses on the object.

In order to do both these things we need to create the group from an ldif file, we can't do that via the framework.
