RDS - RDWeb and SSO

[Maxell]

Hello,

 

I am in the process of setting up a new RDS farm on Server 2012 R2.

 

Is it possible to set up Web SSO for users from external computers? If so, can anyone point me in the right direction?

 

Currently, users have to login to the initial form-based login, then login again when launching an application from the menu. I have found guides to achieve SSO from domain-joined computers, but not external ones.

 

Any ideas very gratefully received.

 

Mark.
