Failover question

[jonr@destar.net]

This is probably a stupid question but the docs I have been reading have forced
me to ask. If the master goes down the slave should automatically pick up the
authentication requests, correct?

So far, from what I have read, it says that I need to copy the db over, stop the
master, start a couple of services on the slave, the then bring up the slave to
be able to answer requests.

If this is the case, should I instead run two masters with one backing up the db
to the other?

Thanks for all the help,

Jon
