Sendmail + Cyrus-Sasl2 (SMTP Authentication)

[shuajoh]

Hello guys,

I'm trying to get SMTP Authentication to work on my el6 server which is running Sendmail. Below are the configs/output from the server.

# sendmail -d0.1
Version 8.14.4
Compiled with: DNSMAP HESIOD HES_GETMAILHOST LDAPMAP LOG MAP_REGEX
MATCHGECOS MILTER MIME7TO8 MIME8TO7 NAMED_BIND NETINET NETINET6
NETUNIX NEWDB NIS PIPELINING SASLv2 SCANF SOCKETMAP STARTTLS
TCPWRAPPERS USERDB USE_LDAP_INIT

sendmail.mc:
define(`confAUTH_OPTIONS', `A')dnl
TRUST_AUTH_MECH(`LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `LOGIN PLAIN')dnl
DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
LOCAL_CONFIG
ESASL_PATH=/usr/lib/sasl2
define(`confENVDEF', `-DSASL')dnl
define(`conf_sendmail_LIBS', `-lsasl')dnl

# cat /etc/sasl2/Sendmail.conf
pwcheck_method: saslauthd
mech_list: LOGIN PLAIN
saslauthd_path: /var/run/saslauthd/

# cat /etc/sysconfig/saslauthd
SOCKETDIR=/var/run/saslauthd
MECH=pam
FLAGS=

# cat /etc/sasl2/Sendmail.conf
pwcheck_method: saslauthd
mech_list: LOGIN PLAIN
saslauthd_path: /var/run/saslauthd/

# testsaslauthd -u xxxxx -p xxxxxx -s smtp
0: OK "Success."

Here's a log of a failed SMTP Auth

I'll really appreciate any assistance i can get.
