SMTP-AUTH problem with vchkpw

I tried to migrate my mail service (qmail+vpopmail+mysql) to the
64-bit Gentoo platform and almost succeeded, but SMTP-AUTH problem
blocked me.

Right now I have no multilib 64-bit hardened Gentoo system with
netqmail-1.06, vpopmail-5.4.30-r2, dovecot-2.0.13 and some other
stuff. Everything seems working fine, except SMTP-AUTH function.

My mailer on this new server shows me:

SEND  - connected to SMTP server
SEND  - authenticating (plain)...
SEND  - Server reports error. The response is: authentication failed (#5.7.1)
SEND  - authenticating (login)...
SEND  - Server reports error. The response is: authentication failed (#5.7.1)
SEND  - WARNING: there were no compatible authentication mechanisms detected

Here goes my config /var/qmail/control/conf-smtpd:
-----------------------------------------------------------------------
TCPSERVER_OPTS="${TCPSERVER_OPTS} -R"
QMAIL_SMTP_PRE="${QMAIL_SMTP_PRE} spamdyke -f /etc/spamdyke/spamdyke.conf"
QMAIL_SMTP_CHECKPASSWORD="/var/vpopmail/bin/vchkpw"
[[ -n "${QMAIL_SMTP_CHECKPASSWORD}" ]] && {
        [[ -z "${QMAIL_SMTP_POST}" ]] && QMAIL_SMTP_POST=/bin/true
        QMAIL_SMTP_POST="${QMAIL_SMTP_CHECKPASSWORD} ${QMAIL_SMTP_POST}"
}
-----------------------------------------------------------------------

mail control # ls -la /var/vpopmail/bin/vchkpw
-rws--x--x 1 root vpopmail 129128 Jul  1 02:18 /var/vpopmail/bin/vchkpw

Dovecot using vpopmail driver working fine.

userdb {
  driver = vpopmail
}

May be someone knows how can I solve that problem with SMTP-AUTH?
