Hi, I am configuring Virtual domains and mailboxes on CentOS 5.5 using MySQL for data maps and SASL for SMTP Auth. As far as I can say, I have followed The Book of Postfix.
Dovecot and Postfix both use the same tables for authentication and POP authentication works perfectly. However any attempt at SMTP authentication gives the following (SASL?) error: May 7 01:02:23 Server1 postfix/smtpd[11760]: auxpropfunc error invalid parameter supplied May 7 01:02:23 Server1 postfix/smtpd[11760]: sql_select option missing May 7 01:02:23 Server1 postfix/smtpd[11760]: auxpropfunc error no mechanism available and then followed by: May 7 01:02:24 Server1 saslauthd[11666]: do_auth: auth failure: [user=XXXX] [service=smtp][realm=XXXXX] [mech=pam][reason=PAM auth error] My /usr/lib/sasl2/smtpd.conf reads: log_level: 8 pwcheck_method: auxprop mech_list: PLAIN LOGIN auxprop_plugin: sql sql_verbose: yes sql_engine: mysql sql_hostnames: localhost sql_user: XXXXXX sql_passwd: XXXXXX sql_database: postfix sql_select: select password from mailbox where username = '%...@%r' I would really appreciate your help in figuring whats wrong.
