Hi All,
We've abandoned previous efforts to use pam_mysql with postfix and
cyrus-sasl (see previous post...), and have decided to make use of our
own Ruby libraries to access the DB. Therefore, we're now attempting to
use pam_ruby. I started out with the example implementation found here:
http://ruby-pam.sourceforge.net/pam-ruby.html.
Not having any luck so far telnet'ing to our SMTP server on port 2525
and authenticating, so I'm wondering what could be wrong.
I ran saslfinger -s on the server and got this output:
-bash-3.2# saslfinger -s

Also looked a bit at the sasl2-sample-server and -client (with ln -s
/usr/lib/sasl2/smtpd.conf /usr/lib/sasl2/sample.conf):
sasl2-sample-server -s rcmd -p 8000
then in another terminal
-bash-3.2# sasl2-sample-client -s rcmd -p 8000 -m PLAIN 127.0.0.1

And if it matters, /etc/sysconfig/saslauthd has "mech=PAM" in it.
Any ideas? Am I even testing this out correctly?
