Creating/deleting folders stopped working

[Vladislav Tchernev]

Hi all,
Since recently, I am having a weird problem. When I create a new user via the 
web GIU, kolab reports that the operation is successfull but it doesn't 
create a mailbox for the new user. When I try to delete the newly created 
user the the process hags showing "User Deleted, awaiting cleanup..." in the 
web interface. If I try to create an imap folder manually via cyradm it's 
working. Trying to delete the same folder via the kolab GUI still fails. So 
for some reason kolab is not able to perform any disk related operations. The  
permitions for /kolab/var/imapd/spool/domain/****/user/ looks right. 
Any ideas?
