Question : OWA and ISA Issue

I have three SSL sites behind ISA 2006.  One is OWA 2003.  I can use a web listener with SSO installed to force users to use their RSA token (RADIUS) to get ACCESS to all three sites, but then I can't seem to use that same form for OWA (without losing the SSO functionality that presents all three sites to users once their RSA token is accepted).  I am OK with users heading on the the OWA site and authenticating to IT with ITs forms based auth rather than having ISA 2006 pass on authentication from the ISA 2006 form (since it HAS to be RADIUS anyway).  ISA is stubbon and treats OWA like OWA even when I set up a rule to treat it like a regular web site.  I have tried numerous options and shut off numerous filters.  Still the RADIUS SSO FORM on ISA 2006 works great and the other two sites work great but OWA fails during the /exchnage to /exchweb redirect and even putting in the URL manually fails.  Any ideas?  I know it's a goofy config-it was forced on me.

Answer : OWA and ISA Issue

You are going to have to use OWA on one listener with FBA.  I don't care if the FBA is from the OWA box or use the one from ISA,...but it is best to do it with the ISA and let it delegate to the OWA box.

Then the RADIUS can only be used with the other two sites using a different listener.   I don't see anyway to have RADIUS with all three sites on one listener unless you went totally without FBA
