[Dovecot] Syncing shared mailboxes

[Knud Dombrowsky]

Hi,
while trying to sync the mailboxes of several users who use and share
their mailboxes dsync prints this message:

dsync-local(user-who-uses-shared-mailbox): Warning: Subscriptions file
/home/user-who-uses-shared-mailbox/Maildir/subscriptions: Removing
invalid entry: shared/sharing-user/shared-folder

The problem is: Every user has to subscribe the shared folder again
after each run of dsync...
Is dsync capable of syncing shared mailboxes? Are there any
preliminaries to do so?

thanks in advance, Knud

[Dovecot] noaclright

[Knud Dombrowsky]

Hi,
I recently upgraded to openSuse 12.1 which comes with dovecot 2.0.14.
Because of mail-client-problems I am running one dovecot which requires
authentication via a client-certificate and another one which can be
used without a certificate. (Configurations can be found below.)
Since the upgrade our shared mailbox is no longer visible. I tried to
repair this by setting the ACLs once again (using imap-acl in
Thunderbird) but every time I try to set a new ACL the tool says
noaclright and dovecot logs the following messages:

Dec  7 14:31:14 mailbox dovecot: imap(sharing-user): Error:
fstat(/home/sharing-user/Maildir/.shared-folder/dovecot-acl.lock)
failed: No such file or directory
Dec  7 14:31:14 mailbox dovecot: imap(sharing-user): Error:
file_dotlock_open(/home/sharing-user/Maildir/.shared-folder/dovecot-acl)
failed: No such file or directory

Needless to say the file exists and its contents looks like it should.
(Every line is an ACL like user=testuser ilrws)
I took a look at the changelog from 2.0.14 onwards and since it says
nothing about my problem I am not looking forward to compiling dovecot
myself and installing it.

Any ideas why this is happening? Is this a known problem?

Any help is appreciated,
Knud
