Since I don't have a map over your system, I can only do what Ian G
did (reading between the lines), and unfortunately I come to the
conclusion that your scheme indeed may be a bit flawed.  Please note
that this may be due to lack of information!!!  So how should it be then?

Users (maybe also machines) authenticate to a local AD or similar
using whatever mechanism the actual organization can support.  This is
based on the assumption that users (employees) are locally known
etc.  After successful authentication the result is a SAML assertion
redirecting to the application (cloud service?). 

What's the point with that you may wonder?  Administration becomes
a breeze and you may also have different authentication schemes in
different places.  The latter may seem bad but if banks have plotted
with the idea that all clients should have the same security solution,
we wouldn't be able to send money from bank A to bank B.  That's
the true power of federation versus an all-mighty directory that is
always filled wth incorrect information.

I would also not completely overlook the fact that maybe 75% of all EU
banks use some kind of OTP solution for their on-line services.  OTP
sure has warts but it doesn't require middleware and card-readers.
