Advice regarding ldap (building my tree)

Hello,

I'm setting up my openldap server and I would like an advice from experimented users.

My domain is dc=mycompany,dc=org

My company will have: - employees - clients - partners

How should I organise my tree ? for example ? o=MyCompany, dc=mycompany,dc=org o=Client1, dc=mycompany,dc=org o=Client2, dc=mycompany,dc=org o=Partner1, dc=mycompany,dc=org

Or can I group clients ? o=Client1, ??=Clients, dc=mycompany,dc=org o=Client2, ??=Clients, dc=mycompany,dc=org What would be "??" if I want to make a group called Clients ?

Or my approach is not good ? If someone has advices (or links that describe a real life case) I'll be more than happy to read them.

Thank you
