VDI Access Policy

I've used the Horizon View iApp to secure access to our VDI environment but I have a query regarding the access policy. During the build I said 'no' to SecureID as although I do want 2FA we are using Radius. So now I want to add 2FA auth onto the access policy.

 

For the browser logons this is simple as I added a 3rd password field and used a variable assign to switch the fields as neccessary for either AD or Radius auth.

 

For the client logon page though there does not seem to be an option to add a 3rd password field. My only option is to select from a dropdown whether I want the form to support Windows, RSA, Disclaimer, Radius or Smart Card.

 

I could do the Radius auth, come back to a 2nd logon page for AD credentials, then to AD auth, but as with the browser logon I'd much prefer if this could be done on a single page. Is this possible?

 

As a side note - why on earth does the iApp tempalte only support SecureID as a 2FA method?
