We have several tickets:

https://fedorahosted.org/freeipa/ticket/433

https://fedorahosted.org/freeipa/ticket/3659

https://fedorahosted.org/freeipa/ticket/4498

If you see https://fedorahosted.org/freeipa/ticket/4498#comment:6 we 
discussed this use case.
And I was about to fork it as said but then I realized that there is not 
good way on the KDC to determine the host you are coming from.
So IMO it should be a policy decision on SSSD.
There are two options:
- short term solution: allow SSSD to have a local overwrite to require 
OTP if server offers different options.
- longer term solution: actually have a per host policy that is 
centrally managed that is fetched per host and enforced by SSSD.

Before filing tickets I would like to hear opinions on the matter.
