dovecot - Oct 2009 - Error: userdb lookup

Hi list,

I am trying to get rid of the "Error: 
file_dotlock_create(~/.dovecot.lda-dupes) failed: No such file or 
directory" by adding home directories to my virtual users (ldap).
I want this home dir' to be specified like this:
/var/vmail/$USER/home/
and the sieve scripts to go to:
/var/vmail/$USER/home/sieve/

So as suggested before in this list, I have replaced:
user_attrs = mailMessageStore=mail,mailQuotaSize=quota_rule=*:bytes=%$
by
user_attrs = mailMessageStore=mail,mailQuotaSize=quota_rule=*:bytes=%$, 
=home=/var/vmail/%u/home

But then the userdb lookup fail and it tells me this in the log:
deliver(user at mydomain): Error: userdb lookup: 
connect(/usr/local/var/run/dovecot/auth-master) failed: No such file or 
directory

This is strange because:
a. the socket is at /var/run/dovecot/auth-master
b. it is working flawlessly with the original user_attrs value

So I am thinking that this setting is totally ignored by dovecot at some 
point.

I must be missing something.
Any help please ?

My postfix's master.cf with the deliver relevant line:
dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f 
${sender} -d ${recipient}

My postfix's main.cf with the deliver relevant line:
mailbox_command = /usr/local/libexec/dovecot/deliver

I suppose you added -d parameter to deliver also.

Change either that from auth { socket { .. } } path or change
auth_socket_path setting.

Changing user_attrs can't cause this error. Adding -d parameter to
deliver does.

If you're using dovecot transport, you should probably remove the
mailbox_command since it only causes confusion.

Also one more possibility to fix this instead of using deliver -d
parameter is to set:

plugin {
  home = /var/vmail/%u/home
}
