The client settings are:

ipaclient_mkhomedir
ipaclient_no_ntp
ipaclient_ssh_trust_dns
ipaclient_no_ssh
ipaclient_no_sshd
ipaclient_no_dns_sshfp

ipaserver_password has been renamed to ipaadmin_password
ipaserver_dm_password has been renamed to ipadm_password

With using the name password for the password return it will be hidden
automatically and an error message will still be visible.

There is no way to repair a server installation like it is possible with a
client.

These global variables are initialized in the dns module in the
dns.install_check function. The settings are needed to be able to do a
proper dns setup in the ipaserver_setup_dns ansible module.

The support for external cert files is not complete yet.
