Now I'm more confused.  I changed Dovecot to listen only on a specific 
IP address - and I still see localhost log lines:

Jun 27 12:03:27 bubba dovecot: auth: 
ldap(SomeUser at MyDomain.com,127.0.0.1): invalid credentials

The only other thing I can think of - Postfix runs on this server and 
uses Dovecot SASL.  Is it possible the Dovecot auth log line is caused 
by a Postfix connection attempt?
