[Dovecot] Auth wit multiple ldap configfiles

Hi,

trying to deliver local mails with exim over dovecot.

The problem is, that i logged in with a username from ldap to imap For this i created in dovecot.conf

auth imap { args = /path/to/dovecot-ldap.conf ...... }

And for delivery i use

command = /path/to/dovecot/deliver -d $local_part@$domain

in the exim.conf

$local_part is diferent to the loginname in the ldaptree

So i create in dovecot.conf

auth deliver { args = /path/to/dovecot-ldap_deliver.conf }

Sometime dovecot check the "auth deliver" section and sometimes the "auth imap" section i created.

I don´t understand why dovecot doesn´t check allways both sections?!?

P.S.: Sorry my english :)
