When installing ADFS I didn't see any option to link it to any particular domain. The only choices I saw were "Active Directory","LDAP", and "SQL" for the attribute store.
Windows 2008 R2 x64 with ADFS 2.0 on a multi-domain forest. ADFS server is joined to the chosen domain and the service account is in that chosen domain.
I finished the install and it's currently working, but how do I ensure that it will only work with one child domain in my forest and not other child domains or orther trusted external forests?
