I thank you very much for these hints. What suggested by Jan is very 
useful and fully working.

I only have to notice what follow. I experience very difficult in 
kronolith using preauthenticate hook in horde. If I enable 
preauthenticate hook, kronolith can't find free/busy time during meeting 
subscriptions. It shows the same error of freebusy url not found.
And I can't open "remote" calendar of other users.

My preauthenticate hook is very simple, it only set this variable:

   $_SESSION['imp']['server'] =$information[0]['mailhost'][0];

where $information[0]['mailhost'][0] has read by LDAP.
