I've been using this guide to set up a custom 2-factor authentication provider: VMware View 5.1 RADIUS Authentication Setup
When using Access-Challenge packets to request additional data from the user, would it be possible to display contents of Reply-Message (attribute 18) to the user in View Client?
For example, instead of the text "next $ProviderName response", display the contents of the Reply-Message field. Or better yet, display a form similar to the one that is shown when RSA SecurID requires a PIN change.
The latter is probably a long shot, but I'd be pretty happy with just displaying some custom text. I'm using View 5.1.0.
