Are you returning system_user userdb attribute? Extra groups from /etc/group are not applied without this. ---Aki TuomiDovecot oy -------- Original message --------From: Jason Perry <[email protected]> Date: 28/08/2018 04:27 (GMT+02:00) To: Aki Tuomi <[email protected]> Cc: [email protected] Subject: Re: Issue sharing folders with Thunderbird Hi Aki, they are. 3. 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.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.
