I need to find a solution where I can use two-form authentication for OWA
and RPC over HTTP.  I am new to RSA and new to ISA.

It seems that I can use ISA in conjunction with a RSA systems to provide RSA
authentication.
1) Can I use RSA auth with OWA? (It sounds like from reading others posts
that this configuration works. What is the users experience? Does a user use
forms based authentication using RSA and then again using Domain account
login or just the RSA auth?)

2) Can I use RSA auth with Outlook RPC over HTTP? If no, is there any other
solution for Outlook RPC over HTTP that provides two-form authentication?

The only other way I can think of to deploy a full Outlook client would be
to use a VPN solution that can use RSA auth instead of using the new
Exchange/Outlook 2003 RPC over HTTP solution. It seems like Microsoft
Outlook would support RSA auth.

Could someone give me a brief description of this scenario and/or any
pertinent articles?

Thanks
Ken
