authenticated bits=0

I'm using Sendmail-8.13.4, and recently enabled SMTP-AUTH.

What is "authenticated bits=0" referring to?   The "bits" field in TLS 
refers to the keysize, I believe.

First, the headers I'm seeing are:

    Received: from [192.168.1.99] ([192.168.1.99])
    (authenticated bits=0)
    by forrie.com (8.13.4/8.13.4) with ESMTP id j8GI3HbH011192
    (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=OK)

The second portion is TLS.

Corresponding syslog:

    Sep 16 13:53:21 forrie sm-mta[79497]: AUTH=server,
    relay=[192.168.1.99],
    authid=forrie at forrie.com, mech=CRAM-MD5, bits=0

Sendmail, as I understand, allows relaying based on successful AUTH,
ie: you don't need special rules beyond that really.

Some providers (Sympatico?) have in their SMTP headers 
"Authenticated-User: username at domain.com" - (and this
is not SASL-specific).  I would like to place that in my Sendmail headers.

So basically, I'm tracing all steps to ensure I have this configured
and running properly.


Thanks.
