Issue sharing folders with Thunderbird

[Aki Tuomi]

Are you returning system_user userdb attribute? Extra groups from /etc/group are not applied without this.

Hi Aki, they are.
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.db4. Users I'm testing with are part of the sharedusers group in /etc/group
The dir /var/lib/dovecot/db has this for permissions:drwsrwsrwx.  2 root    sharedusers   33 Aug 27 21:12 db
the user operations is a member of “sharedusers” in /etc/group.  I even chmod’ed the permissions after to rw for global and I get the same error/result.
The file does appear to get written to.  For example, lets say user u2.name creates a folder called “starbucks” and uses the IMAP commands to share it out to user operations.  It seems to write to the acl_shared_dict file in /var/lib/dovecot/db/shared-mailboxes.db with an entry likeshared/shared-boxes/user/u2.name/operations1
And it writes to the ~/Maildir/.starbucks/dovecot-acl file for u2.user with an entry like:user=operations lrw
So it appears to be working.  However, if I log into Thunderbird with the user operations account and go to subscribe, I do not see “starbucks” in the list of available folders.  And I still get the nfs_flush_chown error.
Is there anything else I can be doing with the file/dir permissions?
Thanks.

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 user2. When I try to set
permissions via IMAP commands I get in /var/log/dovecot.logAug 26 20:33:24
imap(operations): Error: nfs_flush_chown_uid: chown(/var/lib/dovecot/db)
failed: Permission denied3. 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.db4. Users I'm testing
with are part of the sharedusers group in /etc/group5. IMAP commands DO
write to the file:[root at dal-notify-01
Maildir]# cat /var/lib/dovecot/db/shared-mailboxes.dbshared/shared-boxes/user/u1.name/u2.name1shared/shared-boxes/user/operations/u2.name1shared/shared-boxes/user/u1.name/operations1shared/shared-boxes/user/u1.name/operations16. It will also
write to the user's /home/operations/Maildir/.JasonAlert/dovecot-acl fileuser=u1.name ilrw However if I got
into Thunderbird and try to subscribe, none of the shared folders are
listed.  Can anyone help??  Thanks!! Dovecot version =
