This is sendmail *offering* authentication. It's not *requiring* it.

If you have FEATURE(`access_db') and a line:

127.0.0.1                       RELAY

in /etc/mail/access, it should relay mail for localhost without
requiring authentication (and these are default settings).

You don't have "M=a" or "M=Ea" in the DAEMON_OPTIONS line for your MTA,
do you?
