PEAP-EAPTLS or EAPTLS Single Sign On with Pre-Logon does not work

Single Sign-On (SSO) with the "Perform immediately before user logon" (pre-logon) option set with registry based certificates is not supported. Registry based certificates utilize either EAP-TLS or PEAP-EAP-TLS authentication methods.

This is because user registry certificates live in HKEY_CURRENT_USER, which does not get loaded until immediately after the user logs in.  Therefore, because we are doing "pre-logon", when the supplicant attempts to find credentials, there is no user context loaded hence no certificates available to the supplicant.
