It is really different RSA on ISA2004 and ISA2006, is still a thing that I hate
but my taste about technology is not open to discussion :(
I was thinking to have a CAS on my DMZ and have that one published directly to
internet (by that way I will have RSA just one time), but Microsoft doesn't
support CAS on the DMZ, that is why I'm trying to have it working with ISA
asking the RSA credentials and passing it to the CAS, which is already
protected with RSA.

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).
