Is that true? Did MS make an official statement regarding no support for
CAS in a DMZ?
What happend to SD3+C One of those D's is Secure in Deployment. Not
supporting the CAS in the DMZ violates the third D.

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 L
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).
