[Samba] Sendmail active directory authentication

[Mark Foley]

I'm trying to get Sendmail to authenticate with Active Directory. I have saslauthd configured
for Sendmail authentication, /etc/sasl2/Sendmail.conf:

pwcheck_method: saslauthd
mech_list: LOGIN PLAIN

and saslauthd is started as: /usr/sbin/saslauthd -a shadow

This fails when doing testsaslauthd on a domain user.

Is there a way to get sendmail to authenticate using domain credentials?

My distro (Slackware) does not provide PAM, but I can get it if needed.
