[1]	Configure as a FreeIPA Client on the Host you'd like to set FreeIPA Replication Server, refer to here.
[2]	On FreeIPA Master Host, Add a replication Host to [ipaservers] group. Furthermore, it needs to resolve Address Resolution on Master Host and Replica Host. If you are using FreeIPA integrated DNS but not set reverse zone, Configure like follows.
