Hullo Users,
I setting up a mailserver with smtp authentication and the backend
database is mysql 5.1.53 with pam_mysql and cyrus-sasl2 2.1.23 on
slackware linux 13.1.When i telnet to test my server side
authenication it gives me the error
below:

rootxxxxxx:/etc/postfix# postconf -a
cyrus
dovecot

***@xxxx:/etc/postfix# saslauthd -v
saslauthd 2.1.23
authentication mechanisms: getpwent pam rimap shadow ldap

Error from maillog file
xxxxx postfix/smtpd[1475]: xsasl_cyrus_server_next: decoded response:
xxxxx postfix/smtpd[1475]: warning: SASL authentication failure:
All-whitespace username.

xxxxx postfix/smtpd[1475]: > localhost[127.0.0.1]: 535.5.7.8 Error:

on doing a testsaslauthd :

#testsaslauthd -u ***@mydomain -p password -f
/var/state/saslauthd/mux -s smtp
0: OK "Success."

When i do a Check for server-side SMTP AUTH configuration. I get the
output below:

You are using this chain:

postfix -> libsasl -> saslauthd -> pam -> pam_mysql

However you configured /usr/lib64/sasl2/smtpd.conf to go this way:

postfix -> libsasl -> mysql

Try this in /usr/lib64/sasl2/smtpd.conf:

pwcheck_method: saslauthd
mech_list: plain login

remove /usr/local/lib/sasl2/smtpd.conf. You should not need it.
