[Dovecot] Connection refused with auth-master after upgrading to Dovecot 1.0 rc 28

[Jason Warner]

Fedora pushed out an update to Dovecot 1.0 rc 28 today. After
upgrading, mail isn't delivered to local recipients. My log file is
full of error messages similar to the following:

Apr  2 12:56:32 mail deliver(user at domain.com):
net_connect(/var/run/dovecot/auth-master) failed: Connection refused

I'm including some snippets from my dovecot.conf file that pertain to
the auth-master file:

protocol lda {
  # Address to use when sending rejection mails.
  postmaster_address = postmaster at brashers.com

  mail = maildir:/home/vmail/mail/%n

  # Hostname to use in various parts of sent mails, eg. in Message-Id.
  # Default is the system's real hostname.
  #hostname =

  # Support for dynamically loadable plugins. mail_plugins is a space separated
  # list of plugins to load.
  #mail_plugins =
  #mail_plugin_dir = /usr/lib/dovecot/lda
  mail_plugins = cmusieve
  mail_plugin_dir = /usr/lib/dovecot/lda

  # Binary to use for sending mails.
  #sendmail_path = /usr/lib/sendmail

  # UNIX socket path to master authentication server to find users.
  auth_socket_path = /var/run/dovecot/auth-master
  #auth_socket_path = /home/vmail/mail/auth-master
}

  socket listen {
    master {
      # Master socket provides access to userdb information. It's typically
      # used to give Dovecot's local delivery agent access to userdb so it
      # can find mailbox locations.
      path = /var/run/dovecot/auth-master
      #path = /home/vmail/mail/auth-master
      mode = 0600
      # Default user/group is the one who started dovecot-auth (root)
      user = vmail
      group = mail
    }
    #client {
      # The client socket is generally safe to export to everyone. Typical use
      # is to export it to your SMTP server so it can do SMTP AUTH lookups
      # using it.
      #path = /var/run/dovecot/auth-client
      #mode = 0660
    #}
  }

I have been beating my head against this trying to change the
permissions to 0777, changing the directory of the socket, changing
the auth user, and just about anything else I can find in any thread
that relates to this error. Any help would be greatly appreciated.
