[horde] Sort names in shared address books

[Dominik Erdmann]

Hello,

I'm using a shared address book for an user. If I creat a new message 
and open the address book window the names are sorted by "lastname, 
firstname" and displayed as "firstname lastname". How can I change the 
option for sorting the names? The Preferences => Address Book => Name 
Format will be ignored.

Best regards,
Dominik
