Thank you for the reply p@rick. By your recommendation I did add the postfix
user to sasl:
sudo adduser postfix sasl
Adding user `postfix' to group `sasl' ...
Adding user postfix to group sasl
Done.
I ran "saslfinger -c" and "saslfinger -s" and it does appear that many of the
relevant services are chrooted.
I wasn't quite sure, however, so I attached the full output of both commands.
Of interest was the error message (not sure if it's relevant though):
Cannot find the smtp_sasl_password_maps parameter in main.cf.
Client-side SMTP AUTH cannot work without this parameter!
I then changed the OPTIONS of /etc/default/saslauthd to what you reccomended:
#OPTIONS="-c -m /var/run/saslauthd"
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd"
Restart went fine:
sudo service saslauthd restart
Stopping SASL Authentication Daemon: saslauthd.
Starting SASL Authentication Daemon: saslauthd.
And the socket does appear to be changed (auth.log):
Sep 7 11:50:25 saslauthd[8695]: detach_tty : master pid is: 8695
Sep 7 11:50:25 saslauthd[8695]: ipc_init : listening on socket:
/var/spool/postfix/var/run/saslauthd/mux
However there are still curious errors (I don't think I've seen the auxpropfunc
error before):
Sep 7 11:25:02 gpasswd[8432]: user postfix added by root to group sasl
Sep 7 11:26:18 postfix/smtpd[8489]: auxpropfunc error invalid parameter
supplied
Sep 7 11:26:18 postfix/smtpd[8489]: _sasl_plugin_load failed on
sasl_auxprop_plug_init for plugin: ldapdb
And an attempt at localhost telnet still fails:
telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 ComputerName ESMTP Postfix (Debian/GNU)
auth plain {my-hash-here}
535 5.7.8 Error: authentication failed: authentication failure
Further, postfix is still giving similar errors when authentication fails:
Sep 7 11:53:20 postfix/smtpd[8821]: connect from
localhost.localdomain[127.0.0.1]
Sep 7 11:53:37 postfix/smtpd[8821]: warning: SASL authentication problem:

Sep 7 11:53:37 postfix/smtpd[8821]: warning: localhost.localdomain[127.0.0.1]:
SASL plain authentication failed: authentication failure
Not entirely sure how to proceed from here; advice appreciated :)
