[Freeipa-users] IPA installation and SSHD configuration - What is being configured?

[J N]

When I have a look at either ipa-client-install or Ansible role 'ipaserver' I come
across the options for OpenSSH:

ipaclient_no_ssh
ipaclient_no_sshd <--- What I'm interested in.

I want to install a IPA server and my question is: 
What exactly is being configured, and should I use this option?
