saslauthd + PostFix producing password verification and authentication errors
- by Aram Papazian
So I'm trying to setup PostFix while using SASL (Cyrus variety preferred, I was using dovecot earlier but I'm switching from dovecot to courier so I want to use cyrus instead of dovecot) but I seem to be having issues. Here are the errors I'm receiving:
==> mail.log <==
Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed
Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure
==> mail.info <==
Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed
Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure
==> mail.warn <==
Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed
Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure
I tried
$testsaslauthd -u xxxx -p xxxx
0: OK "Success."
So I know that the password/user I'm using is correct. I'm thinking that most likely I have a setting wrong somewhere, but can't seem to find where. Here is my files.

Here is what I'm using for /etc/postfix/sasl/smtpd.conf
log_level: 7
pwcheck_method: saslauthd
pwcheck_method: auxprop
mech_list: PLAIN LOGIN CRAM-MD5 DIGEST-MD5
allow_plaintext: true
auxprop_plugin: mysql
sql_hostnames: 127.0.0.1
sql_user: xxxxx
sql_passwd: xxxxx
sql_database: maildb
sql_select: select crypt from users where id = '%u'
As you can see I'm trying to use mysql as my authentication method. The password in 'users' is set through the 'ENCRYPT()' function.
I also followed the methods found in http://www.jimmy.co.at/weblog/?p=52 in order to redo /var/spool/postfix/var/run/saslauthd as that seems to be a lot of people's problems, but that didn't help at all.
Also, here is my /etc/default/saslauthd
START=yes
DESC="SASL Authentication Daemon"
NAME="saslauthd"
# Which authentication mechanisms should saslauthd use? (default: pam)
#
# Available options in this Debian package:
# getpwent -- use the getpwent() library function
# kerberos5 -- use Kerberos 5
# pam -- use PAM
# rimap -- use a remote IMAP server
# shadow -- use the local shadow password file
# sasldb -- use the local sasldb database file
# ldap -- use LDAP (configuration is in /etc/saslauthd.conf)
#
# Only one option may be used at a time. See the saslauthd man page
# for more information.
#
# Example: MECHANISMS="pam"
MECHANISMS="pam"
MECH_OPTIONS=""
THREADS=5
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r"
I had heard that potentially changing MECHANISM to MECHANISMS="mysql" but obviously that didn't help as is shown by the options listed above and also by trying it out anyway in case the documentation was outdated.
So, I'm now at a loss... I have no idea where to go from here or what steps I need to do to get this working =/ Anyone have any ideas?
EDIT:
Here is the error that is coming from auth.log ... I don't know if this will help at all, but here you go:
