object-type resource - cant create new / broken after rename

[Matthias Busch]

Hey,

after renaming one of the object-types (for example car) in the 
webadmin, it lost some attributes (ou, owner, ...) which can not be 
added manually (missing from dropdown list)

so i looked in another kolab instance where the resources are untouched, 
the object classes seem right
additionally, I can not create a new object type (for example boat) 
because even when I add the object classes top, mailrecipient, 
kolabsharedfolder) I will still be missing ou and owner to add to attributes

am I missing an objectclass? if so which one?
how can i fix the other object types (car, conference room, tickets, 
projector) - i have ldap-utils if need be

and how am I supposed to create new classes? or is it currently bugged?

thanks
