If RSA works with ISA Server 2006 the same way it does with ISA Server 2004,
it won't work like it does when the RSA Agent sits on the OWA server (or in
this case the CAS server). This has to do with RSA not providing the
appropriate API calls (the ones the RSA Agent makes) in the SDK given to
Microsoft when it was used to incorporate RSA at the ISA Server 2004 level.
I had to work through this one a couple of years ago when we were trying to
get true two-factor authentication working with OWA but were doing RSA
authentication at the ISA Server. The information above came directly from
RSA.
Again, I'm not sure this still applies to ISA Server 2006 and Exchange 2007
but I think the best you might be able to hope for if you implement RSA at
the ISA Server is a single web page for RSA authentication at the ISA Server
and then a FBA page for OWA on the CAS server. You will probably also run
into the issue that the RSA hook in ISA Server does not check to make sure
that the RSA credentials and OWA credentials belong to the same person (i.e.,
User A can authenticate to RSA and User B can authenticate to OWA).
