dovecot - Feb 2012 - Passdb disconnected unexpectedly when trying to do Director with LMTP

Hi there,

I'm running Dovecot 2.0.16 just set up the director with cut&paste from 
the wiki. It's working & running fine for pop/imap connections (as 
verified by doveadm director status user), however when I specify 'RCPT 
TO' for a (tcp) lmtp connection straight away I get:

451 4.3.0 <xxx at yyy.com> Temporary user lookup failure

and in the logs:
2012-02-11T14:22:54+00:00 xxx dovecot: lmtp(27997): Error: passdb 
lookup(xxx at yyy.com): Disconnected unexpectedly

I'm sure this is an obvious issue for someone who's come across it 
before. The /var/run/dovecot/director-userdb socket is on the system; 
exactly the same permissions as the standard auth-userdb

Here are the relevant bits of my config (I'm setting lmtp to listen on a 
different port than normal). Backend password database is mysql if that 
makes any difference.

lmtp_proxy = yes

service lmtp {
   inet_listener lmtp_test {
     port = 2450
   }
}
protocol lmtp {
   auth_socket_path = director-userdb
}

Thanks,

Mark

Aren't there any other errors logged? I think there should be some error
logged from either auth or director process.

Although director is missing one error, but auth should have also logged an
error in that case. Anyway, fixed by
