We have RSA authentication working properly. A custom theme with the 'Password 2' field renamed to 'Passcode'. All our external testing displays this field properly. All connectivity is with the Receiver for HTML5, and rather simplistic policies & profiles.
We have one client that does not see the 'Passcode' field at all when they access our NSG. They are running Windows 7 with IE11, and a very secured OS (I believe USGBC settings).
Any ideas why this might be happening?
(I did find VHDs from the NIST for testing purposes; will be trying to duplicate the issue with a VM.)
