[Evolution] Type in name in the To Field, doesn't search the working LDAP server(s). How to?

["Matthew Western" <mwestern affairs net au>]

hi People,
I have an LDAP connection to my Exchange server working fine...  I can in a
new message click the 'To' button and select the LDAP address book.  But,
the default is my contacts folder which is fine.

If I type in the name of a person on the server that i know exists in the
too (without having it in my Contacts list) it doesn't find it.  How can i
make my address book either have the LDAP server as the default or make it
search the LDAP directory somehow??  any help would be much appreciated.
Thanks
Matthew
