[Dovecot] Shared subscription, acl-list and uidvalidity(s)
Hello,
I'm running dovecot-1.1.8/Maildir/ACL plugin. I sucessfully set up a Maildir shared between users of the unix group 'doveshared' via a public namespace, unix permissions and ACL files.
The location of my public namespace is /path/to/public. I tried 2 sub-setups :
First setup
drwxrws--- 4 root doveshared 4096 Jan 30 13:39 public -rw-r----- 1 root doveshared 18 Jan 30 13:38 public/subscriptions
I first connect (in Thunderbird) to dovecot with user 'hummel', then with user 'doveimap'. The following files are created in /path/to/public/ :
-rw------- 1 doveimap doveshared 40 Jan 30 14:03 dovecot-acl-list -rw------- 1 hummel doveshared 8 Jan 30 14:03 dovecot-uidvalidity -rw------- 1 hummel doveshared 0 Jan 30 14:02 dovecot-uidvalidity.4982fa7a
I've got my own idea about what they're used for, but can you explain what they are supposed to be ?
I guess the uidvalidity files are UIDVALIDITY, not for the mailboxes the namespace holds (since my understanding is that the uidvalidities of mailboxes are stored in the first line of dovecot-uidlist files), but for the namespace itself (in case it is destroyed and then recreated for instance). Am I right ? Why 2 files ?
Second setup
I follow the 'Shared subscriptions' section of the wiki :
drw-r-s--- 4 root doveshared 4096 Jan 30 14:19 public -rw-r----- 1 root doveshared 18 Jan 30 13:38 public/subscriptions
As expected, dovecot (and it shows in the logs), has not sufficient permissions to create the files above (dovecot-acl-list, dovecot-uidvalidity, dovecot-uidvalidity.4982fa7a). What are the consequences ?
Thanks.

Any idea, anyone ?

Sorry to insist, but I need this setup. Timo ?

dovecot-acl-list caches information about listable mailboxes. dovecot-uidvalidity* files are used to assign a unique UIDVALIDITY value when a new mailbox is being created (or actually opened for the first time).
If you want the files to be group-readable, make the /path/to/public directory also group-readable. At least I think that should do it.
I guess the uidvalidity files are UIDVALIDITY, not for the mailboxes the namespace holds (since my understanding is that the uidvalidities of mailboxes are stored in the first line of dovecot-uidlist files), but for the namespace itself (in case it is destroyed and then recreated for instance). Am I right ?
They're used for all the mailboxes that are created under that namespace.
Why 2 files ?
Implementation optimization issue. It helps to avoid locking.

Probably not good? Why not give it permissions?
