Two factor auth for one pool only

Hi,

We have a running VMware Horizon View 5.2 environment with one connection server and a paired security server

All is working well.

Now we are planning to introduce two-factor (smsotp) authentication, but only for one pool

Is this possible?

Can we add a second connection server and enable two factor for example?

But what about security server(s)

Thanks.
