OK... I found it.

In Dovecot master.conf, I enabled smtp-auth. Under that, it seems you 
must set the user to postfix or each time you restart dovecot the auth 
file is recreated and is owned by root... resulting in the failure. I 
looked for the file earlier and it was not there. It seems to have 
appeared due to enabling smtp-auth, but I did make other edits before 
restarting the service.

Inside of service auth I have the following:

   # Postfix smtp-auth
   unix_listener /var/spool/postfix/private/auth {
     mode = 0666
     user = postfix
    }

I am considering adding group = postfix as well as the file is now group 
root.

Thanks,
