[Zope-CMF] change ownership on Zope objects

[Marie Robichon]

One of the administrators of our Plone site has changed services.  Given 
that our user authentication is via LDAP and that this person has write 
access to some parts of our site I now want to change the ownership of 
the pages he created in order to remove his write access.

What method is used to display the owner information in the manage_owner 
window?  I have written a script that queries the catalog and returns 
the Creator and owner_info() but this information is different again to 
the owner that is displayed in the manage_owner window.

Thanks in advance for your help
