I think the part your missing is the PAM mechanism. If you're going to
use
"rcmd" as the service, then you need to have an /etc/pam.d/rcmd to tell
SASL
w/ PAM where to look for authentication information. Better yet, use '-s smtp' to have sasl2-sample-server look at /etc/pam.d/smtp for PAM configuration instead of 'rcmd'. This should just work for you.
Are you stuck elsewhere with the postfix+SASL stack or is this as far as you've gotten? Let me know.
Thanks very much for the time to help Jason.
That was as far as I got. I diligently stopped right there wanting to get that right before proceding to take my working mail down <smile>.
Someone else also pointed out my misunderstanding as you described above. I swapped rcmd to smtp and all was well. I was following the Book of Postfix examples literally, but I didn't see anything to make me think to do otherwise. With the help I got from the other person and now you, too, I was able to get it going. So I have that part behind me and working.
Thanks again for the help.
Best, Scott
