dovecot - Oct 2012 - /var/run/dovecot/auth-userdb failed

Hi,
I work on test server and if I send an email on log i read

 lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed:
Permission denied (euid=8135(vmail) egid=8135(vmail) missing +r perm:
/var/run/dovecot/auth-userdb, euid is not dir owner)

This is my dovecot.conf:

auth_mechanisms = plain login
info_log_path = /var/log/dovecot
listen = 0.0.0.0
log_path = /var/log/dovecot
login_greeting = Dovecot IMAP Server ready.
mail_location = maildir:/home/vmail/%d/%u
mail_privileged_group = vmail
passdb {
  args = /etc/dovecot/dovecot-ldap.conf.ext.fabry
  driver = ldap
}
protocols = pop3 sieve imap
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
 unix_listener auth-userdb {
    mode = 0600
    user = root
    group = root
  }
}
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb {
  driver = ldap
  args = /etc/dovecot/dovecot-ldap.conf.ext.fabry
}
lda_original_recipient_header = X-Original-To
lda_mailbox_autocreate = yes
lda_mailbox_autosubscribe = yes
protocol lda {
  mail_plugins = $mail_plugins sieve
   info_log_path = /var/log/dovecot-lda.log
}
managesieve_notify_capability = mailto
managesieve_sieve_capability = fileinto reject envelope encoded-character
vacation subaddress comparator-i;ascii-numeric relational regex imap4flags
copy include variab
les body enotify environment mailbox date
plugin {
    sieve_dir = /home/vmail/%d/%u/sieve
    sieve = /home/vmail/%d/%u/sieve/.dovecot.sieve
}


What did I do wrong?

The problem is that LDA (local delivery agent or lmtp service)
is not able to look up the destination mailbox in userdb.

The socket /var/run/dovecot/auth-userdb is currently only
readable or writable by user root since mode is set to 0600,
not readable or writable by other groups.

http://wiki2.dovecot.org/LDA#Virtual_users

You'll need to set up a auth-userdb socket for dovecot-lda so it
knows where to find mailboxes for the users. LDA is running under
the virtual mailbox user and group "vmail", so you need to grant
this user or group access to /var/run/dovecot/auth-userdb.

You could do this by using group memberships and set mode = 0660
or simply make it world-readable-writable with mode = 0666:

unix_listener auth-userdb {
   mode = 0666
   user = root
   group = root
}
