Re: ACLs, shared, public, virtual mailboxes not working

15 Feb 2018

      Hello,
The user1 is my original user, user2 is the second user that I want to
have access to the public and shared folder.
I am not seeing a subcommand rights for doveadm
Thanks.
DAve.

Since you have obfuscated your data it is hard to tell what's going on,
especially as in your previous log you have 'user=user' and now you have
user1 and user2.
You can try
doveadm rights -u victim folder
to see what sort of rights dovecot thinks it's seeing.

Hi!
It seems you are running 2.2.33.2 =)
Also,
Feb 12 08:48:40 imap(user@example.com): Debug: Mailbox
'public/TestFolder' matches global ACL pattern 'public/TestFolder'

/home/vmail/public/TestFolder/dovecot-acl
Feb 12 08:48:40 imap(user@example.com): Debug: acl vfile: reading file
/home/vmail/public/dovecot-acl
it seems there are some folder specific ACLs, can you check these?

Hello,
I'm running Dovecot 2.2.3, and am having issues with my public
folders, shared folders, and virtual/ALl folders apparently ACLs are
on that list as well.
I was debugging an unrelated problem with my smtp server and got the
following dovecot debug log output. Below is also a doveconf -n output
as well as my shared-folder definition file and my global-acls file.
What I'm trying to accomplish is:

Have a public folder that any user on the system can put messages
into and respond to.
Have a shared folder in which user1@example.com and
user1@example2.com can exchange messages.
For each user on the system give them a Virtual/All folder for *all
of their messages.

I'd appreciate any help. As an aside if anyone sees an issue with my
SSL ciphers list i'd appreciate knowing that as well, in brief I'm
trying to get the most secure list, pfs, and not worrying about
backware compatibility. If it's not TLS 1.2 I don't touch it.
Thanks.
Dave.
