dovecot - Feb 2011 - Cannot subscribe to shared folders

Hi,

I am unable to subscribe to shared folders with Thunderbird although 
everything seems to be correct (dovecot 1.2).

What does not work? I click "Subscribe..." in Thunderbird. The shared 
mailboxes are listed, all with [ ] (no checkbox). Therefore I mark them 
[x], click "subscribe" and "OK". However, the folders do not
appear in
the folder tree. Furthermore, when I again click "Subscribe..." the 
folders do NOT have the mark [x] any more. This happens on different 
computers with *new* profiles.

My configuration is the following (maybe that is the problem?!):

namespace private {
    separator = .
    prefix =.
    inbox = no
    list = no
    hidden = yes
    location = maildir:~/Maildir-root
    subscriptions = yes
}

namespace private {
    separator = .
    prefix = INBOX.
    inbox = yes
    subscriptions = yes
}

namespace public {
    separator = .
    prefix = Shared.
    location = maildir:/var/mail/shared:INDEX=~/Maildir/shared:LAYOUT=fs
    subscriptions = no
}

The folder /var/mail/shared has appropriate permissions/form:
* Owner: $user:mailuser (all users are member of "mailuser")
* All files 0660, all folders 0770
* There exists a dovecot-shared in every folder
* There exists a dovecot-acl in each folder where each user has the 
permissions "lrwstie"

I switched on "mail_debug = yes" but no messages.

However, the file ~/Maildir-root/subscriptions contains the subscribed 
folders:

Shared.Group1
Shared.Group2
Shared.Group1/Test

Furthermore, I switched on rawlog. Everything seems to be OK as well:

.in-file:
2 subscribe "Shared.Group1"
3 lsub "" "INBOX.*"
5 lsub "" "Shared.*"
6 list "" "INBOX"

.out-file:
2 OK Subscribe completed.
[...]

I am pretty sure it already worked. But it stopped working. Does anybody 
have a hint what could be the problem?

Regards,
Luke

In this case the subscriptions for Shared. are saved in 
~/Maildir-root/subscriptions.

However, may be that this does NOT work in practice?

It works as soon as I set "subscriptions = yes" in the public
namespace :-(

However, then the subscriptions are saved in the shared folder and the 
users overwrite them themselves :-/

Hi,

I did further investigation on this issue (using raw IMAP commands) and 
I think that this is a bug...

In each case I make sure that all folders are subscribed, that is, the 
subscribe command returns OK and the subscribed folders are written into 
/var/mail/shared/subscriptions and ~/Maildir-root/subscriptions, 
respectively. Just to make sure:

# cat /var/mail/shared/subscriptions
NoSpamDrop
Public
SpamDrop
# cat /home/lukas/Maildir-root/subscriptions
Shared.NoSpamDrop
Shared.Public
Shared.SpamDrop
#

It turns out that if I set

1.) subscriptions = yes (in the public namespace above)
     the lsub command behaves correct:

     . list "" "Shared.*"
     * LIST (\HasNoChildren) "." "Shared.NoSpamDrop"
     * LIST (\HasNoChildren) "." "Shared.Public"
     * LIST (\HasNoChildren) "." "Shared.SpamDrop"
     . OK List completed.
     . lsub "" "Shared.*"
     * LSUB () "." "Shared.NoSpamDrop"
     * LSUB () "." "Shared.Public"
     * LSUB () "." "Shared.SpamDrop"
     . OK Lsub completed.
     . logout
     * BYE Logging out
     . OK Logout completed.
     closed

2.) ...but with subscriptions = no
     the lsub command returns an empty list ALTHOUGH the folders are
     subscribed:

     . list "" "Shared.*"
     * LIST (\HasNoChildren) "." "Shared.NoSpamDrop"
     * LIST (\HasNoChildren) "." "Shared.Public"
     * LIST (\HasNoChildren) "." "Shared.SpamDrop"
     . OK List completed.
     . lsub "" "Shared.*"
     . OK Lsub completed.
     . logout
     * BYE Logging out
     . OK Logout completed.

Now I am pretty sure that this is a bug. Maybe it is better to file a 
bug report?

Best regards,
Luke
