Trying to get ACLs working, very basic setup:
Virtual users are put into different acl_group via passdb.
u:{PLAIN}B::::::userdb_acl_groups=g
The global acl file restricts what they can do.
- group-override=g
- group=g lr
Shouldn't this mean, that the group rights override the user rights?
The effect that I see though is, that the user "u" then may not do anything, not even lookup and read.
Further to this experiment, I made the ACLs to not use any group settings at all, only trying to lock down the server for anybody, like that:
root@xxx:/etc/dovecot# cat dovecot-acl
- user=archiv lr
- owner lr
- authenticated lr
- anyone lr
Yet, I still can delete messages from anywhere - What am I missing?
Below system setup info (dovecot from bigmichi1 ppa):
root@xxx:/etc/dovecot# doveconf -n # 2.2.13 (6bb26098a45c): /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-64-generic x86_64 Ubuntu 12.04.4 LTS mail_debug = yes mail_location = maildir:~/Maildir mail_log_prefix = "%s(%{auth_user}): " mail_plugins = " acl fts fts_solr mail_log notify" namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/passwd driver = passwd-file } plugin { acl = vfile:/etc/dovecot/dovecot-acl fts = solr fts_autoindex = yes fts_solr = url=http://localhost:8983/solr/ mail_log_events = save copy delete undelete expunge mailbox_create mailbox_rename mailbox_delete mail_log_fields = uid box msgid from subject } protocols = " imap" ssl_cert =
The virtual users all act as the system user, their names are just icing for auditing.
