saslauthd, sendmail, and AUTH

[Eric Ewanco]

I am having a heck of a time getting Sendmail 8.13.1 to authenticate 
using Cyrus saslauthd 2.1.13.  I need help isolating my problem to 
either saslauthd or Sendmail.

Saslauthd has worked fine with Cyrus imapd for years.  If I test it 
using testsaslauthd, it authenticates fine with a service name of smtp 
or imap. 

Sendmail, however, refuses to provide the AUTH command and complains

Jul 12 14:11:49 polycarp sendmail[1322]: AUTH warning: no mechanisms

I have followed several sets of instructions for configuring Sendmail 
for saslauthd and none have worked. 

I am invoking saslauthd with the -a shadow option.

Is there a way to determine which mechanisms are available?  I did this:
[root at polycarp eje]# /usr/local/sbin/saslauthd -v
saslauthd 2.1.13
authentication mechanisms: getpwent pam rimap shadow

How come the "mechanisms" cited by the -v option don't match up with the 
mech_list in the configuration file (below), but rather match the 
"methods"?  Which type of mechanism is Sendmail complaining about?

/usr/lib/sasl2/Sendmail.conf says:

#pwcheck_method: saslauthd
pwcheck_method: shadow
mech_list: PLAIN CRAM-MD5 DIGEST-MD5

I tried running saslauthd in debug mode but it printed out nothing when 
I invoked Sendmail.

sendmail.mc contains:
define(`confAUTH_MECHANISMS',`LOGIN PLAIN DIGEST-MD5')
define(`confAUTH_OPTIONS',`y,p,a')
TRUST_AUTH_MECH(`LOGIN DIGEST-MD5 PLAIN')
...
LOCAL_CONFIG
ESASL_PATH=/usr/lib/sasl2

Thanks!
