Where is KAddressBook LDAP configuration stored

Hi,

In trying to add an LDAP host to KAddressBook, (Settings>Configure 
KAddressBook>Add Host ), the dialog box that pops up will not accept entries.  
(I.e., one can't type in any data -- or even get the cursor to work).

I figure there must be a place to store the data:  perhaps I can edit it 
manually.  So far I've not been able to discover it, and net searches haven't 
helped.  

Could some kind and knowledgeable soul on this list help direct me to 
appropriate help?

KMail 4.9.2 
Fedora 17 (64-bit)

Thanks in advance.
   James
