[Dovecot] Multiple authentication databases

[Alexander Shikoff]

Hello,

I'm trying to setup multimple auth. databases with Dovecot 1.0 alpha2.
I wrote in dovecot.conf next lines 
(as was described at http://wiki.dovecot.org/moin.cgi/MultipleAuth)

auth_debug = yes
auth_verbose = yes
auth default {
        mechanisms = plain
        user = root
        passdb sql {
                args = /usr/local/dovecot/etc/dovecot-mysql.conf
        }
        passdb pam {
                args = pop3
        }
        userdb sql {
                args = /usr/local/dovecot/etc/dovecot-mysql.conf
        }
        userdb passwd {
        }
}

If user is virtual and placed in SQL database all works perfectly.
But system users can not login:

Sep 23 12:27:58 orion dovecot: auth-worker(default): mysql: Connected to 127.0.0.1 (exim)

How can I setup multiple auth. databases correctly? Please, help!
Thanks in advance, 
	Alexander
