Horde problem - Unable to synchronise

[Michal Juriš]

Hello,

I've just finished installing horde on our Kolab server machine following 
these instructions: 
http://wiki.kolab.org/index.php/Kolab2_Installation_-_Horde

But now I get lot of these errors on the top of horde's page. Only mail is 
working (only INBOX, no subfolders), but all other apps just display no data


Horde/Kolab: Unable to synchronise address book "xxx at xxx's Address Book": NO, 
Invalid mailbox name
Error  Horde/Kolab: Unable to synchronise shares: NO, Mailbox does not exist
Error  Horde/Kolab: Unable to synchronise address book "xxx at xxx's Address 
Book": NO, Invalid mailbox name
Error  Horde/Kolab: Unable to synchronise address book "xxx at xxx's Address 
Book": NO, Invalid mailbox name
Error  Horde/Kolab: Unable to synchronise shares: NO, Mailbox does not exist
Error  Horde/Kolab: Unable to synchronise calendar "xxx at xxx's Calendar": NO, 
Invalid mailbox name


I don't really know what can be the cause ..


Thanks for any hint ...
