Hello,

I have a user sharing a folder to me (and other users). This has worked 

for me for a time. And it is still working for some users, but not for me.

I'm using thunderbird (17.0.3, ubuntu 12.04 package). My server is 

dovecot 2.1.9 (it's the same since it works). The user sharing its mailbox is:

$ sudo doveadm user t userdb: t home : /home/generica/02/001002 uid : 1002

he is sharing its mailbox "cron". This is its dovecot-acl:

root@myotis31:/home/generica/02/001002/Maildir# cat dovecot-acl user=<other user> kxeilprwts user=<my user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts

I can subscribe to this folder:

# sudo doveadm mailbox subscribe -u <myuser> shared.t.cron # sudo doveadm mailbox list -u <myuser> -s INBOX ... ... shared.t.cron

but when I try to access to this folder through thunderbird (what I 

really do in TB is subscribe/unsubscribe to it, because it is not actually listed in the folder list), I get:

Feb 26 13:35:03 myotis32 dovecot: imap(<myuser>): Error: Couldn't create namespace 'shared.' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota

With doveadm commands I can access to the shared folder from my user 

(not the user sharing):

$ sudo doveadm search -u <myuser> mailbox shared.t.cron | wc -l 652

Other users can use this shared folder without any (apparent) problem.

I have attached my doveconf -n.

Any idea?
