##### 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?
|
|

|
|
|
|
##### 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 AND chef_environment:#{node.chef_environment}")

|

|
##### Do master stuff
|
|
|
|
# write better tests to see if freeipa is already set up.
