I've dug through all the cyrus-sasl distributions that seem like they would have the distrubution. Searching the net turns up that there is a cyrus-sasl-authd package, but it doesn't show up in a yum list on my machine.
It seems like this should just be there, according to everything I've found on the web. But it doesn't turn up.
CentOS 7 is not using sysv init, but systemd, so there is no use for init scripts. Instead there are service files available under /lib/systemd/system/saslauthd.service.
You can start saslauthd by running systemctl start saslauthd and to make it start automatically, you need to run systemctl enable saslauthd, if it is your concern.
