That is a good resource (essentially a HTML-ized version of
/usr/share/sendmail/cf/README), but the original poster might find
this chunk out of /usr/share/doc/smm/08.sendmailop/paper.ascii.gz more

                [no short name] List  of  options  for  SMTP
                AUTH  consisting  of  single characters with
                intervening white space or commas.

                    A   Use the AUTH= parameter for the MAIL FROM
                        command only when authentication succeeded.
                        This can be used as a workaround for broken
                        MTAs that do not implement RFC 2554 correctly.
                    a   protection from active (non-dictionary) attacks
                        during authentication exchange.
                    c   require mechanisms which pass client credentials,
                        and allow mechanisms which can pass credentials
                        to do so.
                    d   don't permit mechanisms susceptible to passive
                        dictionary attack.
                    f   require forward secrecy between sessions
                        (breaking one won't help break next).
                    p   don't permit mechanisms susceptible to simple
                        passive attack (e.g., PLAIN, LOGIN), unless a
                        security layer is active.
                    y   don't permit mechanisms that allow anonymous login.

                The first option applies to  sendmail  as  a
                client, the others to a server.  Example:

                    O AuthOptions=p,y

                would  disallow  ANONYMOUS as AUTH mechanism
                and would allow PLAIN and LOGIN  only  if  a
                security  layer (e.g., provided by STARTTLS)
                is already active.  The  options  'a',  'c',
                'd',  'f',  'p', and 'y' refer to properties
                of the selected SASL  mechanisms.   Explana-
                tions  of  these  properties can be found in


                the Cyrus SASL documentation.

So the OP's file extract:

    define(`confAUTH_OPTIONS', `A p')dnl

is absolutely fine. Either commas or spaces can be used to separate
the options, so he could use the equivalent:

    define(`confAUTH_OPTIONS', `A,p')dnl
