Hi All,

I've pored over the wiki, read through the archive, and have what I believe should be a working set-up, but I can't seem to get my shared namespace to work correctly. Any guidance would be much appreciated.

I started off using a flat file for acl_shared_dict and ran into the same problem recently reported with the shared-database file getting chown'd to the first user to touch it with 0600 permissions. So I thought I'd give it a whirl with sqlite.

Here are the (hopefully) relevant bits from dovecot -n (the entire output is posted below). This is dovecot 1.2.9 running on a freshly installed ubuntu 10.4 server:

namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:/home/staff/%%n/Maildir:INDEX=~/Maildir/shared/%%u list: children plugin: acl_shared_dict: proxy::acl dict: acl: sqlite:/etc/dovecot/acl-shared-dict.conf

acl-shared-dict.conf looks like this:

connect = /home/staff/dovecot/acl-shared-ns.sqlite

map { table = acl_shared_ns pattern = shared/shared-boxes/user/$to/$from value_field = has_visible_folders fields { from_user = $from to_user = $to } }

/home/staff/dovecot/acl-shared-ns.sqlite is set 0666, and I can add records to it from the sqlite command line as a normal user. The table was created with:

CREATE TABLE acl_shared_ns (from_user, to_user, has_visible_folders, PRIMARY KEY (from_user) ON CONFLICT REPLACE);

When I attempt to SETACL from a telnet imap session, I get the following errors in mail.err:

Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: sqlite: exec(INSERT INTO acl_shared_ns (has_visible_folders,to_user,from_user) VALUES ('1','chobbs','IOchoa')) failed: file is encrypted or is not a database (26) Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): read(/var/run/dovecot/dict-server) failed: Remote disconnected Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): acl: dict commit failed Jun 9 22:10:23 imap2 dovecot: dovecot: child 8268 (dict) killed with signal 11 (core dumps disabled)

Running that same "INSERT INTO..." as the IOchoa user from the sqlite command line works just fine.

At this point any further deleteacl or setacl commands simply hang, presumably because there's no longer a running dict process.

Here is the entire output of dovecot -n:
