[Dovecot] setacl fails - does not find dovecot-acl file

[Michael Stilkerich]

Hi,

  I'm using dovecot 2.0.13 that ships with Ubuntu 11.10.




and group read/writable by the group mail (hence mail_access_groups=mail).

Relevant parts of my config:

mail_plugins = acl
mail_location = maildir:/home/dovecot/%u
mail_access_groups = mail

namespace {
  type = private
  separator = /
  prefix =
  inbox = yes
  hidden = no
  subscriptions = yes
}
namespace {
  type = shared
  separator = /
  prefix = shared/%%u/
  location = maildir:/home/dovecot/%%u:INDEX=/home/dovecot/%u/shared/%%u
  subscriptions = no
  list = children
}

protocol imap {
  mail_plugins = $mail_plugins imap_acl
}

plugin {
  acl = vfile
}
plugin {
  acl_shared_dict = file:/home/dovecot/shared-mailboxes
}










fcntl (also tried flock, same behavior).

I'm not using chroot.

I appreciate any help to get this sorted out.

Thanks,
  Michael

I tried setting up a shared namespace as documented in the wiki to enable the sharing of a mailbox between two users. I have a Maildir(++) directory for each user. Each user has a system account. The Maildir of each user is owned by the user's system account When I try to create an ACL in a telnet session, the command fails with an internal error. The log shows: dovecot: imap(michael): Error: fstat(/home/dovecot/michael/.test/dovecot-acl.lock) failed: No such file or directory dovecot: imap(michael): Error: file_dotlock_open(/home/dovecot/michael/.test/dovecot-acl) failed: No such file or directory The error occurs whether a (manually created) dovecot-acl file exists or not. The dovecot-acl.lock file is created by not removed afterwards. Subsequent setacl commands will timeout waiting for the lock to be released until I delete it manually. If I create the dovecot-acl file manually and provide access to another user, the getacl command will correctly show the permissions and the other user can access the folder. setacl will still fail to modify the acl file, however (same error). Another thing that irritates me is that dovecot seems to use the dotlock locking method, although I explicitly set lock_method to
