Hi All, I have a mailing list I'd like to archive and share with a handful of users. The users are all in OpenLDAP.

10-auth-system.conf.ext is setup with "driver=pam" so it appears anyone in LDAP who already is able to SSH into the server may also connect to dovecot with same username/password they use in LDAP.

I have a shared mailbox directory called LISTS_Archive. The system directory is /home/shared_imap. I can connect to dovecot using LDAP credentials (using Thunderbird) and this shared folder (LISTS_Archive) is grayed out. I assume I have acls wrong?

What I want is for users in LDAP to access the LISTS_Archive imap folder as a shared folder for everyone. Only R/O access however (which is 'lr' in acl file I think).

Would someone please point out what I've missed? Thank you.
