[horde] sorting order of address

[steven.TSE]

Hi, I have added several LDAP entries in turba/config/source.php, however, i
found some of them are sorting by last name, but others are not...  How can
I set it sort on the first name?  Thankyou

Moreover, everytime i select the LDAP entry in address book, it need to
click "search" to make the query.  How can i make it search automatically
whenever i click on the drop down list?

Thankyou very much!

Best Regards,
Steven Tse
