[Dovecot] LMTP auth problem

[Cor Bosman]

hey all,  im  getting the following error:

Apr 14 14:29:44 lmtpdirector1 dovecot: auth: Error: passdb(scorpio,127.0.0.1): Auth client doesn't have permissions to do a PASS lookup: /var/run/dovecot/auth-userdb mode=0666, but not owned by UID 112(dovecot)
Apr 14 14:29:44 lmtpdirector1 dovecot: lmtp(18298): Error: user scorpio: Auth PASS lookup failed


My config.  Director servers running both imap and lmtp with a matching set of real servers accepting imap/lmtp. Imap is working fine, and has been working fine for a while. Im trying to add lmtp to the director, but i cant seem to get that working.  We're passing passdb on to the real servers. How does this work with lmtp?

protocols = imap lmtp

protocol lmtp {
  auth_socket_path = director-userdb
}

lmtp_proxy = yes

# passdb check on real servers
passdb {
   driver = static
   args = proxy=y nopassword=y
}
