Remote Desktop Web Access and Remote Desktop Gateway SSO Through APM

If you are going to 11.6, we are going to be publishing an iApp template that uses the new VDI profile to replace the RDG functionality. I've tested with RDWA publishing resources that go through this new proxy and it seems to work fine.

As far as trying to pre-auth connections to the RDG servers, I wouldn't recommend disabling APM for requests for the RPC proxy, as that leaves a giant security hole that defeats the purpose of using APM. Although I haven't tested it, it should be possible to pre-auth the RDP clients by creating an NTLM machine account (aka, joining the BIG-IP to the domain), creating an NTLM auth config that references that machine account, manually attaching an ECA profile to the APM virtual server, and creating an iRule to enable clientless mode for the RD client connections. You wouldn't be getting SSO with the credentials used in RDWA, however you shouldn't get prompted for credentials either as long as the client machines are joined to the domain.

Basically, if you are going to 11.6 anyway, I recommend going with the new VDI profile iApp, since it will take care of all the configuration for you.
