I've installed Windows 2012 R2 and enabled the ADFS (3.0?) feature. After installation, it asks to configure ADFS, but this step requires a user account that is a domain administrator, as it wants to create certificate containers and SPN records. In ADFS 2.0, you could install in standalone mode which required only local admin rights, storing everything in the Windows Internal Database. If this still possible with the latest version? If so, how do I configure ADFS in standalone mode?
