Where exacly should I "hack" the code to achieve this?
And how exactly can I tell cyrus to use a mailbox name diferent from  
the username, will a PTLOADER be able to do this?

To make things harder, I don't know C, I'm just reading documentation  
as need, although I might get some help from somewhone who knows but  
he's not that aquainted to cyrus, so any starting points would be  
wonderfull.

Perhaps another config var could be added to the ldap PTLOADER so that  
we can provide the maildrop ldap attribute name, besides maildrop of  
course(this might be another way).

Well, what I think the ldap ptloader could gain is give the user the  
ability to provide the atribute he wants to retain from an ldap query.  
Just some other ideas to improve your ptloader.

Thanks!
