OK, gurus, I've spent the last 2 days crawling through all of the posts
and web postings regarding shared folders, and I simply cannot get it to
work. I'm sure that there is something simple that I've overlooked, but
cannot for the life of me see it :)
Here's my current config:
# 2.2.9: /etc/dovecot/dovecot.conf
# OS: Linux 3.16.0-46-generic x86_64 Ubuntu 14.04.3 LTS xfs

All of our users are "real" (no virtual users or domains) and only a
single domain supported. We have a user, rself, that is attempting to
share his inbox with a few others that also need access to it. So the
corresponding ACL files:
root@srv56:/mail/data/shared/rself# ls -la /mail/data/shared/rself/
total 20
drwx------ 4 rself mail 79 Aug 24 15:22 .
drwxrwx--- 7 mail mail 71 Aug 24 16:01 ..
-rw------- 1 rself mail 17 Aug 24 15:22 dovecot-acl-list
drwx------ 10 rself mail 130 Aug 24 12:28 mailboxes
drwx------ 2 rself mail 12288 Aug 25 16:25 storage
-rw------- 1 rself mail 70 Aug 24 12:28 subscriptions
And the contents of dovecot-acl-list:
root@srv56:/mail/data/shared/rself# cat dovecot-acl-list
1440447778 INBOX
root@srv56:/mail/data/shared/rself#
And the mailbox-specific files:
root@srv56:/mail/data/shared/rself/mailboxes/INBOX/dbox-Mails#
ls -la
total 4
drwx------ 2 rself mail 24 Aug 25 08:16 .
drwx------ 3 rself mail 23 Aug 24 12:28 ..
-rw------- 1 rself mail 24 Aug 24 15:22 dovecot-acl
root@srv56:/mail/data/shared/rself/mailboxes/INBOX/dbox-Mails#
Content:
root@srv56:/mail/data/shared/rself/mailboxes/INBOX/dbox-Mails#
cat dovecot-acl
user=musrey akxeilprwts
root@srv56:/mail/data/shared/rself/mailboxes/INBOX/dbox-Mails#
Now, the global ACL dictionary (just a flat file, not enough users to
justify SQL :)
root@srv56:~# ls -la /mail/dict/
total 12
drwxrwxr-x 2 root mail 4096 Aug 24 18:05 .
drwxr-xr-x 5 root root 4096 Aug 23 08:51 ..
-rw-r--r-- 1 rself mail 40 Aug 24 18:05 shared-mailboxes
And contents:
root@srv56:~# cat /mail/dict/shared-mailboxes
shared/shared-boxes/user/musrey/rself
1
root@srv56:~#
So, as far as I can tell from my RTFM activities, I think the
configuration is correct. Now, I go to attempt to check the ACL using
doveadm, and I get this:
root@srv56:~# doveadm acl debug -u musrey Shared/rself/INBOX
doveadm(musrey): Error: Can't open mailbox Shared/rself/INBOX:
Mailbox doesn't exist: Shared/rself/INBOX
root@srv56:~#
WTH, over? So, not thinking this is an ACL issue, but simply a
namespace issue - either I have the shared namespace configured
incorrectly, or I'm using it incorrectly in attempting to identify
rself's INBOX when trying to verify that the ACL is working. So, I
thought to myself, let's try a mailbox list, so I executed
root@srv56:~# doveadm mailbox list -u musrey
ACT!
ACT!/General
AES Outdoors
AES Outdoors/Christy
AES Outdoors/Gwen
.... (many, many mailboxes in here - I should probably eliminate
some of them :)
VMWare
Watchguard
Xata Corporation
Xata Corporation/Mike Brossman
Xata Corporation/Mike Uremovich
INBOX
root@srv56:~#
But no "Shared" or "rself" to be found.
Help, please. I'm quickly going bald over this one.
