It seems you can check both "passwords" and "2FA" under the user.
I was hoping I could create a HBAC such that certain hosts would
only allow 2FA, but I can't see an obvious way to do that.
Is it possible? Help on how would be great. If not, feature
We have several tickets:
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.
If we are using a FAST channel using the credentials of the host then
you may be able to know (probably requires changes in the KDC to
internally retain/convey the information).
This is possible via SSSD, but will not work via kinit done by a
generic user, so normal kinit's would require 2FA all the time.
Can kinit do FAST? Is there some kind of kinit flag to use FAST?
May be in such setup we will require all clients to use FAST for the
accounts that have several options configured.
Then we will know the principal used to armor the connection and can
make policy decisions based on it.
