Hi Aki, they are.
- The permissions for the file are: root@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
- 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 like
shared/shared-boxes/user/u2.name/operations 1
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:
- Shared mailboxes do not appear under subscriptions in Thunderbird for another user
- 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
- The permissions for the file are: root@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
- Users I'm testing with are part of the sharedusers group in /etc/group
- IMAP commands DO write to the file: [root@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
- 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!!
