Re: sasl seems to be ignoring my Sendmail.conf

I can only speak to the cyrus-sasl side of things (we use Postfix not 
Sendmail here),
but this smells like there's another config file that you're not editing 
because you don't know it exists.

Maybe your sendmail is running chrooted? If so, the socket that 
saslauthd is listening on
might not be visible to sendmail, or at least not be at the path you 
think it is. On Debian,
saslauthd listens in two locations, one for chrooted postfix and one for 
non-chrooted cyrus.

Maybe some exploratory breaking of things will help. Introduce a 
deliberate typo into a config
file to be sure that something is reading it. Run saslauthd under strace 
or equivalent and see
what files it is asking the OS to read. Stop saslauthd entirely and see 
if sendmail's behaviour
changes.

Also: saslauthd (auth server) doesn't itself read sendmail.conf; that 
looks like it's something
that the libsasl (auth client) library is doing under Sendmail. Make 
sure that you look at
saslauthd's config file (/etc/saslauthd.conf) too.
