./configure --with-sia

# ./dovecot --build-options
Build options: ioloop=poll ipv6 openssl
SQL drivers:
Passdb: checkpassword passwd passwd-file
Userdb: checkpassword passwd prefetch passwd-file static


# ./dovecot --version
1.0.8

# ./dovecot -n
# 1.0.8: /usr/local/etc/dovecot.conf
protocols: pop3
listen: *:10100
ssl_disable: yes
disable_plaintext_auth: no
login_dir: /usr/local/var/run/dovecot/login
login_executable: /usr/local/libexec/dovecot/pop3-login
mail_extra_groups: mail
mail_executable: /usr/local/libexec/dovecot/pop3
mail_plugin_dir: /usr/local/lib/dovecot/pop3
pop3_uidl_format: %08Xu%08Xv
auth default:
  passdb:
    driver: passwd
  userdb:
    driver: passwd


Configuration simplified to determine why authentication is [still] failing.

Any assistance would be greatly appreciated.
