The handbook seems to be missing some instructions.  I tried what it  
says and sendmail does not accept authentication requests.  There is an  
error in the maillog about /usr/local/etc/sasldb.db having group  
permissions.  Changing that to  700 changes the error to one where it  
can't access the file.  Changing the owner of that to root eliminates  
the error messages.  Sendmail then acknowledges that it has auth  
capability.  But it doesn't authenticate anything.  A ktrace shows that  
it tries to access a pipe in /var/pwcheck/pwcheck.  The directory  
exists, but it is completely empty.  Something else is needed to get  
whatever its trying to communicate with up.
