- Configure the mail server as an NIS slave. I'm thinking that this will basically "copy" the user info (username, password, homedir, etc.) on a schedule and store it locally on the mail server (is this how it works?). This covers both issues - power outage and a server dying.
That is what we do here, both for performance and reliability reasons.
But I've read about problems getting password sync to happen quickly. I'd ideally like it to happen immediately (without any manual intervention) but I don't think this is possible.
You are supposed to register YP slaves with the master, who then prods the slaves to update any changed databases. The belt-and-suspenders solution is to additionally set up a cron job on the slave(s) that updates the yp databases every day or so with ypxfr(8).
