dovecot - Jan 2011 - Question about lda & auth_socket_path

Hi all,

storing e-mails (using postfix) via dovecot-lda fails and I assume this
is related with a auth_socket configuration problem. But I am at a dead
end, so perhaps anybody has got a hint for me:

This is dovecot-2.0.8 on Solaris 10:


10-auth.conf and its include:
-----------------------------
...
userdb {
  driver = static
  args = uid=104 gid=104 home=/some/path/%u
}


Relevant parts of 10-mail.conf:
---------------------------------
...
auth_socket_path = /var/run/dovecot/auth-userdb



Relevant parts of 10-master.conf:
---------------------------------
...service auth {
  unix_listener auth-userdb {
    mode = 0644
    user = vmail
    #group   }
}

service auth-worker {
  user = root
}



Relevant parts of 15-lda.conf:
---------------------------------
...
protocol lda {
  # Space separated list of plugins to load (default is global
mail_plugins).
  #mail_plugins = $mail_plugins
}


# ls -l /var/run/dovecot/auth-userdb
srw-r--r--   1 vmail    root           0 Jan 12 15:49
/var/run/dovecot/auth-userdb


Using dovecot-lda for mail delivery or doveadm for user inquirement
fails:

via debug_log_path:
-------------------
Jan 12 16:04:14 auth: Debug: Loading modules from directory:
/dovecot/code/dovecot-2.0.8/lib/dovecot/auth

Jan 12 16:04:14 lda: Debug: auth input:

existence
Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.error] lda: Error:
user djahnke: Auth USER lookup failed
Jan 12 16:04:14 deliver1 dovecot: [ID 583609 local0.crit] lda: Fatal:
Internal error occurred. Refer to server log for more information.

When I use "allow_all_users=yes" everything works fine, so I think
somehow the communication with the socket fails. I cannot see what
I have missed :-(


Any suggestions what I should look for / configure ?

Any help appreciated,
cheers,
Drik

If static is the only userdb, dovecot has no way to know if a user exists or 
not when doing delivery (no auth/passdb involved). So delivery will fail 
unless you explicitly tell him to accept every user with allow_all_users=yes. 
What's wrong with that?
