Those are the defaults in Debian. Do you find 'cyrus' when you run
'postconf -A'?

The Debian default is empty (which is what I use), but I do find files
from sasl2-bin located there.

I have both of those set to "no" on my Debian system.

I use the Debian default of:
smtpd_sasl_mechanism_filter = !external, static:rest

On my Debian systems that file is located at
/etc/postfix/sasl/smtpd.conf and contains:
pwcheck_method: saslauthd
auxprop_plugin: sasldb
mech_list: digest cram-md5

Debian uses /etc/default/saslauthd for saslauthd startup options,
Here are the options I use in that file:
START=yes
DESC="SASL Authentication Daemon"
NAME="saslauthd"
MECHANISMS="sasldb"
MECH_OPTIONS=""
THREADS=5
OPTIONS="-c -m /var/spool/postfix/saslauthd"
File ownership/perms:
~$ ls -dl /var/spool/postfix/saslauthd
drwx--x--- 2 root sasl 4096 Jun 29 13:46 /var/spool/postfix/saslauthd
Postfix is a member of sasl group:
~$ grep sasl /etc/group
sasl:x:45:postfix
On Debian based systems you will need to edit
/usr/lib/postfix/configure-instance.sh
and append 'etc/sasldb' to the list of FILES
that postfix copies to the chroot when it starts:
~$ ls -al /var/spool/postfix/etc/sasldb2
-rw-r--r-- 1 root root 12288 Jun 22 23:36 /var/spool/postfix/etc/sasldb2
After all that is in place, I use the following
to add/list/delete accounts:
saslpasswd2 -c me@desktop
saslpasswd2 -c me@oldPC
sasldblistusers2
