First I have to say that I agree with Dmitri. It would be better to get
proper groups here which are independent of the user entries. The risk
with your approach is that you introduce a prototype solution here that
later on has to be supported for ever.

Nevertheless it might be possible. You have to redefine a couple of
ldap_group_* attributes. E.g. I would suggest to set
ldap_group_object_class to the name of the object class which contains
the directReports attribute. The this attribute just holds user names
you have to set ldap_schema to rfc2307, if it contains DNs than
rfc2307bis is the right choice. If the manager attribute contains DNs
then you can set ldap_user_member_of to it to speed up group membership
lookups, but please do not use it if there are only names.

But even if is works, please make sure you have a good idea how to
migrate this to a proper solution.
