the postfix smtpd daemon cannot talk to saslauthd because postfix is
jailed. i had to edit /etc/init.d/saslauthd to include:

PARAMS="-m /var/spool/postfix/var/run/saslauthd"

keep in mind i'm not using sasl for anything other than postfix. this
might not be where you want things if sasl is used by other processes..

and of course setup the necessary directories to accommodate the above:

mkdir /var/spool/postfix/var/
mkdir /var/spool/postfix/var/run/
mkdir /var/spool/postfix/var/run/saslauthd
chown -R root:sasl /var/spool/postfix/var/

you might have to add postfix to the sasl group as well - i'm sure
someone will chime in if this is not necessary.
adduser postfix sasl

once things are working, you should see some *mux* files in
/var/spool/postfix/var/run/saslauthd/

i hope this helps.
