[Dovecot] vpopmail auth always return "unknown user"

[Toorop]

Hi,

I'm working on a setup of dovecot 2 + netqmail + vpopmail 5.5 but auth 
doesn't works :(

dovecot -n
# 2.0.1: /etc/dovecot/dovecot/dovecot.conf
# OS: Linux 2.6.35.1-rscloud x86_64 Ubuntu 10.04.1 LTS
auth_debug = yes
auth_debug_passwords = yes
auth_mechanisms = plain login cram-md5
auth_verbose = yes
auth_verbose_passwords = plain
disable_plaintext_auth = no
log_path = /var/log/dovecot/dovecot.log
login_greeting = Dovecot ready.
mail_debug = yes
passdb {
   driver = vpopmail
}
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
   driver = vpopmail
}
verbose_ssl = yes
