I fixed the version mis-match by installing sendmail-cf package and
recompiling sendmail.mc. saslauthd is running and conigured according to
your specs. So, I'm not sure what's missing.
Still googling around and found some things that appear to be missing
from the sendmail config, but when I test saslauthd it doesn't appear to
be working.
testsaslauthd -u username -p mypassword
0: NO "authentication failed"
