[Dovecot] Shared mailboxes errors

[Nikita Koshikov]

Hello list,

I'm implementing shared mailboxes on live system and after enabling acl plugin I got errors in my log: 

Jun 17 15:50:33 dict: Error: sql dict iterate: Invalid/unmapped path: shared/shared-boxes/anyone/

I have no clue why this happening, users don't know about new functionality they just use imap as before. Also dict database begin to fill up by records like:

select * from user_shares;
user at domain.com|admin at domain.com|1

But user don't use setacl command.

Searching for the list gave http://www.dovecot.org/list/dovecot/2009-April/038664.html , but question seemed still open. So, can someone give point how to fix\avoid this ?


One more question, on live system it's hard to debug dovecot with mail_debug=yes for all users, can this option be turn on for individual user? or maybe mail_debug stream can be redirected also for individual user ?
