I have an existing OSX Server running both Active Directory/Open Directory/LDAP/and Window Services. I would like to be able to also install Zimbra on this box and have it run seamlessly with the existing Active Directory/Open Directory and LDAP. Is there ANY way of installing this and having it use the existing data so my existing services can keep running? Or do I need to install it on a new box and have that new box slaved to the old box Master for LDAP?
