Code sounds good, but I haven't tested it.
We need to do release for 4.0 and 4.1 first thing tomorrow.
A possible workaround is to disable 2FA for users in mean time.
We should send a warning to freeipa-users mailing list that we are
preparing a release and they should consider disabling 2FA ion the
meanwhile if they are using it.
