[turba] Expand Names doesn't seem to work

[jonathan soong]

Hi

I have a setup which uses a local mysql database to hold addressbooks as 
well as a site-wide LDAP directory for address searching.

When a user clicks "Expand Names", it only searches their local 
addressbook... (if i put in a name that they don't have in their local 
address book but one that exists in the LDAP i get "Please resolve 
ambiguous or invalid addresses."*)*

According to https://webserver.brandeis.edu/pages/view/Network/ImpThree 
, there should be an option in Mail->Options->Addressbooks

This does not appear anymore (is this because Addressbooks were 
separated into Turba???)

Does anyone know where to specify which address books "Expand Names" 
should search?

Thanks in advance,

Jon
