I have updated design page https://www.freeipa.org/page/V4/Authselect_migration#Overview

Here is pull request for that change https://github.com/freeipa/freeipa/pull/1603
non-sssd installation will display and error, stating that this option is not supported any longer,
and offers to run ipa-advise

I did not have any specific Platform in mind in this case. I am not
aware of platform that has freeipa-client and does not have SSSD.

I see, thanks for info.

Reading this, I would be quite fine with removing all the --no-sssd
functionality from client installer and leaving people who want to
configure FreeIPA with nss-pam-ldapd for manual configuration. We have
some ipa-advise plugins for configuring nss-pam-ldapd "authconfig-free"
code already anyway.
