What might be more important is the cyrus imapd configuration.
>From what you reported so far I'm not certain if the delegation fails
within postfix or the IMAP server.
For Cyrus IMAPD you should have:
postuser: kolab
userprefix: user
sharedprefix: shared
For postfix you could also try the fix I suggested here:
