By default, postfix runs in a chroot under /var/spool/postfix.  The 
path that is defined in smtpd_sasl_path in main.cf is relative to that 
path.  So make sure your SASL server is creating the socket file in the
correct place.

For example, in my /etc/postfix/main.cf, I have:

smtpd_sasl_path = private/auth

And in my Dovecot configuration, I have:

path = /var/spool/postfix/private/auth

The file is created by the SASL daemon when its running, and removed when
it isn't running.

Hope this helps!
