##### Security considerations
# All FreeIPA server hosts need to be able to ssh to each other as root to copy replication configs
# That kind of sucks, but what are the real consequences?
# Since they are replicants of each other, this can be justified, since the data is already compromised.
# Can selinux help mitigate this?
#include_recipe "ohai"
include_recipe "sshroot2rootssh"
##### Replication
# We're going to have to
# a) detect any new freeipa_servers
# b) generate ipa-replica-prepare output for them
# c) copy the configs to them
### Behavor
# First node sets special attribute "master"
# First node configures itself with newly generated crypto
# Subsequent nodes comes up
# Subsequent nodes try to to scp their fqdn's configuration from master
# Subsequent nodes negotiate for master
# negotiate for master
freeipa_masters = search(:node, "freeipa_master:true")
if freeipa_masters.empty? then
##### Do master stuff
# write better tests to see if freeipa is already set up.
