dovecot - Dec 2013 - Horde + dovecot metadata support

Hello,

Horde (http://horde.org) has the ability to store its preferences direct into a
users imap mailbox
using imap metadata extension.  There are two implementations of the imap
extension.
 1. a dovecot plugin: http://hg.dovecot.org/dovecot-metadata-plugin
 2. dovecot itself:
http://www.dovecot.org/list/dovecot/2013-November/093243.html

I setup Horde and dovecot-2.2.5 to use this extension and it works well using
1.)
Now, with dovecot-2.2.9, the plugin fail to compile (unrelated problem on my
side).
So I tried 2.) But here I get a Horde-Error "Error in IMAP command
GETMETADATA: Invalid arguments."

I enables mail_debug but saw no helpfull logging.

  mail_attribute_dict = file:/tmp/%Lu/dovecot-attributes
  remote horde.testserver.ip/32 {
    imap_metadata = yes
    mail_debug = yes
  }
Also I created directory /tmp/$my_login_id (mode 777) but dovecot also created
no files.
neither it logs anything about it.

This is a sample imap session generated by horde:
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE
AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
1 AUTHENTICATE PLAIN ***
1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT

3 LIST () "" (*)

3 OK List completed.
4 GETMETADATA "*" (/shared/vendor/kolab/folder-type)
4 BAD Error in IMAP command GETMETADATA: Invalid arguments.
5 LOGOUT
* BYE Logging out
5 OK Logout completed.

Are there any hints or is the metadata extension just not fully implemented in
dovecot?

Thanks,
Andreas

One bug: http://hg.dovecot.org/dovecot-2.2/rev/f64810b00b7f

Then also Horde isn't sending a valid RFC 5464 command. Mailbox wildcards
aren't supported by it. I think it was supported by the earlier drafts, but
removed later. Looks like the previous dovecot-metadata plugin also allows it.
So, I guess I can add it just as well:
http://hg.dovecot.org/dovecot-2.2/rev/0c3071ebe44b
(Noticed only after commit that this was Horde, not Kolab.)

Hello,

thanks to Timo to fix the issue in Version dovecot-2.2.10.
With minimal configuration? Horde-5.1.5 can now store its preferences in an IMAP
folder.

? in dovecot.conf:
imap_metadata = yes
mail_attribute_dict = file:Maildir/dovecot-metadata
