I have installed postfix, courier-imap, and saslauthd with mysql authentication based on this tutorial: http://www.howtoforge.com/virtual-users-and-domains-postfix-courier-mysql-centos5.1
My system is CENTOs 5.2 and I get this error when I try to authenticate with SMTP:
Nov 10 19:29:56 newinstance postfix/smtpd: sql_select option missing
Nov 10 19:29:56 newinstance postfix/smtpd: auxpropfunc error no mechanism available
Nov 10 19:33:58 newinstance saslauthd: do_auth : auth failure: [user=jon] [service=smtp] [realm=mydomain.com] [mech=pam] [reason=PAM auth error]
I am able to send mail unauthenticated through telnet, but mysql authentication is not working. There are no mysql queries being executed by authdaemond. Can someone guide me through a debugging/fix process?
