Sendmail AUTH

[Justin Willmert]

OK, I tried one more alternative, and it worked for some reason. I 
changed /etc/sysconfig/saslauthd so that the 'MECH' line equaled 'pam' 
instead of 'shadow'. Then I changed /usr/lib/sasl2/Sendmail.conf to 
equal 'saslauthd' instead of 'pam'. I tried it with this system, and it 
worked.

Now I'd like to know *why* doesn't the Sendmail.conf file work alone if 
so many of the sites I've looked over only mentioned Sendmail.conf, 
never once hitting on the idea of saslauthd file. I've only found one 
site that suggested the method that worked for me. Could somebody tell 
me a reason, and if nobody can get me a reason, should this be reported 
as a bug to Bugzilla?
