AUTH confirmation with SENDMAIL

[Michael]

If you have any experience with configuring SENDMAIL and AUTH - and
willing to share - I'd appreciate some hints.

Just to get things started:

a) I am building sasl and sendmail myself - errors are likely
self-inflicted.

b) when I start sendmail (-OLogLevel=14) I see:

syslog output: date-string... AUTH: available mech=SCRAM-SHA-1
SCRAM-SHA-256 DIGEST-MD5 OTP CRAM-MD5 PLAIN ANONYMOUS, allowed
mech=EXTERNAL GSSAPI KERBEROS_V4 DIGEST-MD5 CRAM-MD5

FYI: no special attention to mechanisms I recall when building SASL (v1.27)

My sendmail.mc file contains:

dnl # FEATURE(genericstable)dnl
dnl # FEATURE(mailertable)dnl
dnl # FEATURE(virtusertable)dnl
dnl # FEATURE(domaintable)dnl
dnl # FEATURE(access_db)dnl
dnl # FEATURE(blacklist_recipients)dnl

dnl ### AUTH CONFIGURATION
define(`confAUTH_OPTIONS', `A')dnl
TRUST_AUTH_MECH(`LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `LOGIN PLAIN')dnl

The generated sendmail.cf file contains:

root at x066:[/data/prj/aixtools/git/sendmail/sendmail-8.15.2.1/cf/cf]grep
Auth /tmp/sendmail.cf
C{TrustAuthMech}LOGIN PLAIN
O AuthMechanisms=LOGIN PLAIN
# Authentication realm
#O AuthRealm
#O DefaultAuthInfo=/etc/mail/default-auth-info
O AuthOptions=A
#O AuthMaxBits
R$*                     $: $1 $| $>"Local_Relay_Auth" $&{auth_type}
R$* $| $={TrustAuthMech}        $# RELAY

While I do not expect to run as "PLAIN", I am using these values to
verify my understanding of the setup. Suggestions on how to activate
PLAIN/LOGIN are welcome!

Michael
