Classical mistake :-) Correct your "smtpd_sasl_auth_enable" to
"smtp_sasl_auth_enable" and it will work (if your postfix supports sasl).
Don't forget running "postmap sasl_passwd" in your shell before
restarting the server for creating a new postfix-database-file on your
sasl-account(s).

Hint: smtpd_..... is used for authentification for incoming requests.
