Postfix Saslauthd pam authenticate failed

Hi I'm running postfix with the Cyrus SASL authentication daemon.

I've had the system working in the past, but now for whatever reason I'm getting an authentication failure.  I'm using the PAM plugin for salsd to authenticate.  Here is the log of the error:

systemctl status saslauthd

I'm not sure what to make of the auth_pam: pam_authenticate failed: Module is unknown.  This doesn't look promising

Contents of /etc/conf.d/saslauthd

SASLAUTHD_OPTS="-a pam"

Here's the log from journalctl
