[horde] Logout trouble

[jose antonio z.]

Hi:

I´ve installed horde 3, turba and Kronolith in Debian etch.
I use imp for authenticate my user and it´s work fine. When I logout 
from imp, logout icon menu  redirect me to 
http://miserver/horde3/imp/login.php?logout_reason=logout, but when I 
use turba or Kronolith the logout icon menu redirect me to 
http://miserver/horde3/login.php?logout_reason=logout so If I logout 
from turba or Kronolith I´ve to authenticate twice, on horde and imp too.

I need to know where I change logout menu icon in turba and Kronolith.

Thanks

jose a.
