Is it possible to have more than one digital certificate in the "Authentication" certificate slot with the YubiKey 4? I am testing a YubiKey NEO and seems I am only able to use one digital certificate for smart card logon so thought perhaps a YubiKey 4 would allow multiple certificates to be used as authentication such as RDP to a remote Windows Server using digital certificate stored on the YubiKey 4. Thanks! If only one certificate can be used for SCL RDP on the YubiKey 4 is this a PIV limitation, associated with not having a mini driver, or something else?
