ADFS and ASP.NET

Question

Hello

Just looking for clarification on the above topics.

• There are a number of domains with their own AD
• The domain where my ASP.NET application is running hosts the ADFS server (the root domain)
• there are TRUSTs established between each domain and the root domain

Then there shouldn't be a problem? I don't use Forms authentication, instead I explictly need to say in the web.config that I'm using ADFS, am I right?

How does ADAM fit into all of this? I don't see that I need it, as each domain has their own AD. ADAM is a separate user-store to AD?

Is this right, or am I waaaaay off?

Thanks
