Cyrus IMAP with pam_mysql?

OK, first off, my.cnf doesn't get created in the ports install on
FreeBSD, but if you check the startup script, all the parameters are
passed to the mysqld process at that time, if you have a play with the
mysql stuff you can modify that script so that it does read it. In fact
that is necessary if you wan to run with InnoDB tables anyway (you
probably don't for pam_mysql). This is what you can modify the script to
look like, where it also sets the log directories:
#!/bin/sh
DB_DIR=/data01/mysql40
PIDFILE=${DB_DIR}/`/bin/hostname -s`.pid
case "$1" in
start)
if [ -x /usr/local/bin/mysqld_safe ]; then
/usr/bin/limits -U mysql \
/usr/local/bin/mysqld_safe
--defaults-file=/usr/local/etc/my.cnf --user=mysql
--log-bin-index=${DB_DIR}/logs/ajax-logidx.log
--log-error=${DB_DIR}/logs/errlog.log --skip-bdb --pid-file=${PIDFILE}
--datadir=${DB_DIR} > /dev/null &
echo -n ' mysqld'
fi
;;
stop)
if [ -f ${PIDFILE} ]; then
/bin/kill `cat ${PIDFILE}` > /dev/null 2>&1 &&
echo -n ' mysqld'
else
echo "mysql-server isn't running"
fi
;;
*)
echo ""
echo "Usage: `basename $0` { start | stop }"
echo ""
exit 64
;;
esac
Default log directories are in the default data directory, which is
something like /var/db/mysql or somesuch (the location is in the
Makefile for mysql) They are changed in the above script prior to
starting the db server for the first time.
Incidentally, here is my version of the relevant section of pam.conf.
# Mail services
imap auth sufficient pam_unix.so
try_first_pass
imap auth optional pam_mysql.so user=mail passwd=*******
db=mail host=ajax table=mail_users usercolumn=user_col
passwdcolumn=pw_col crypt=2
imap account required pam_mysql.so user=mail passwd=*******
db=mail host=ajax table=mail_users usercolumn=user_col
passwdcolumn=pw_col crypt=2
imaps auth sufficient pam_unix.so
try_first_pass
imaps auth optional pam_mysql.so user=mail passwd=*******
db=mail host=ajax table=mail_users usercolumn=user_col
passwdcolumn=pw_col crypt=2
imaps account required pam_mysql.so user=mail passwd=*******
db=mail host=ajax table=mail_users usercolumn=user_col
passwdcolumn=pw_col crypt=2
pop3 auth required pam_unix.so
try_first_pass
sieve auth sufficient pam_unix.so
try_first_pass
sieve auth optional pam_mysql.so user=mail passwd=*******
db=mail host=ajax table=mail_users usercolumn=user_col
passwdcolumn=pw_col crypt=2
sieve account required pam_mysql.so user=mail passwd=*******
db=mail host=ajax table=mail_users usercolumn=user_col
passwdcolumn=pw_col crypt=2
It occurrs to me that if you haven't enabled the imap port in
/etc/services, that could cause this kink of problem - but seems an
unlikely scenario.
Lastly _MAY BE IMPORTANT______________
From the imapd.conf I have, I can't see the 'sasl_mech_list: PLAIN'
line, so this may be affecting it!
FWIW, I still get shed loads of errors in the logfiles at auth time -
never managed to sort that - and now can't be bothered!
Hope some of this helps! :-)
