Sorry, I should probably explain myself a little better:

When you do an "EHLO" the server should respond with the auth 
mechanisims it supports e.g. PLAIN, LOGIN etc


% telnet localhost 25
Connected to localhost
Escape character is '^]'.
220 local.sendmail.ORG ESMTP Sendmail 8.10.0/8.10.0; Thu, 9 Sep 1999 
10:48:44 -0700 (PDT)
ehlo localhost
250-local.sendmail.ORG Hello localhost [], pleased to meet you
250 HELP

Each of the modes supported has a corresponding security/cy2-* package.
So if for example you wanted to allow the PLAIN and LOGIN methods you 
would need to install cy2-plain and cy2-login. (Of course this is a "bad 
idea" (tm) unless you are implementing TLS as well).  This would then 
use saslauthd to auth the users against /etc/passwd.

In addition to this there are cf (mc) directives as to what mechanisms 
set advertised so I'd check your cf (mc) files as well. Specifically 
look for confAUTH_MECHANISMS and I'm pretty sure there are others as well.

So my questions to you should really have been what cy2-* packages do 
you have installed and what AUTH mechanisms is sendmail actually 
advertising ?

Also have a look at
