Issue sharing folders with Thunderbird

[Jason Perry]

Trying to share folder "JasonAlerts" within mailbox operations to user u1.name
 
Issues:
1. Shared mailboxes do not appear under subscriptions in Thunderbird for another user
2. When I try to set permissions via IMAP commands I get in /var/log/dovecot.log
Aug 26 20:33:24 imap(operations): Error: nfs_flush_chown_uid: chown(/var/lib/dovecot/db) failed: Permission denied
3. The permissions for the file are:
root at dal-notify-01 Maildir]# ls -la /var/lib/dovecot/db/shared-mailboxes.db
-rw-rw-r--. 1 operations sharedusers 197 Aug 26 20:33 /var/lib/dovecot/db/shared-mailboxes.db
4. Users I'm testing with are part of the sharedusers group in /etc/group
5. IMAP commands DO write to the file:
[root at dal-notify-01 Maildir]# cat /var/lib/dovecot/db/shared-mailboxes.db
shared/shared-boxes/user/u1.name/u2.name
1
shared/shared-boxes/user/operations/u2.name
1
shared/shared-boxes/user/u1.name/operations
1
shared/shared-boxes/user/u1.name/operations
1
6. It will also write to the user's /home/operations/Maildir/.JasonAlert/dovecot-acl file
user=u1.name ilrw
 
However if I got into Thunderbird and try to subscribe, none of the shared folders are listed.  Can anyone help??  Thanks!!
