[Dovecot] Stuck with authentication for my dovecot installation.

[Tru Pheenix]

Hello!

I have been following instructions from here to setup dovecot along with
postfix and postgresql and sasl2.

I try to login but I keep getting the following messages in
/var/log/mail.log

My doveconf -n gives the following output

# 2.0.19: /etc/dovecot/dovecot.conf
# OS: Linux 3.2.0-24-virtual i686 Ubuntu 12.04 LTS
auth_debug = yes
auth_verbose = yes
passdb {
  args = /etc/dovecot/dovecot-sql.conf
  driver = sql
}
passdb {
  driver = pam
}
protocols = " imap pop3"
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
  args = /etc/dovecot/dovecot-sql.conf
  driver = sql
}
userdb {
  driver = passwd
}

Please let me know what is wrong.
