ADFS Home Realm Discovery - Active case

Oct 12, 2011 at 8:02 PM

Does anyone know how to enumerate the home realms associated with an ADFS R-STS server for the active client case?

I've been given a scenario where roaming users will have an active client on machines that are not necessarily part of a domain. However, they will attempt to access an RP using domain credentials. I need a way to create a dropdown that enumerates the available IP-STS's that have been trusted on the ADFS R-STS.

In the passive case, the ADFS site contains a home realm discovery ASPX page that serves this function. However, I am not sure how to do it in the active case and haven't gotten to the point where I use Reflector to figure out how the page generates its dropdown.
