You are not clear about what you really want.  If you want it to log to
auth.log instead of messages, then you can use the following in your
sudoers file:

   Defaults syslog=authpriv

The sample file that was mentioned earlier is one source for
information, but the best source is the sudoers(5) man page.  Just
search it for syslog and you will find several settings.
